Resumen

Background: The objectives of the present study were to clinically evaluate the effectiveness of chitosan mouthwash on Plaque formation and to evaluate the antimicrobial activity against salivary Streptococcus mutans (SM) and Lactobacillus (LB).Methods: A total of 20 participants with decay-missing-filled index ≥4 and simplified oral hygiene index score >1.3 were recruited for the study after taking informed consent. All the participants were provided a bottle of chitosan mouthwash in addition to their usual oral hygiene procedure. Baseline salivary SM and LB levels were determined, using chair-side CRT® bacteria test prior giving chitosan mouthwash and after 14 days, during which children are advised to use 10 ml of mouthwash for 60 seconds two times daily. Plaque index score recorded using Silness and Loe plaque index. Paired t-test (or corresponding non-parametric) and percentage comparison method using cross tables were used for statistical analysis.Results: The baseline plaque index score of 0.758 and after 14 days of mouthwash use, it reduced to 0.434. The mean difference in the plaque index showed significant reduction in the plaque score (i.e., with the difference of 0.324). The results showed the antiplaque effects with a short duration of 14 days use of chitosan (CH) mouthwash. The antibacterial activity demonstrated a range of inhibitory effect on salivary SM and LB.Conclusions: CH showed an evident strong effect against salivary SM and LB levels and controlling the plaque biofilm formation. So water soluble CH can be used in new formulations for oral applications not only as antimicrobial agent but also for plaque biofilm control.

Resumen

This report is part of a project to characterize cotton gin emissions from the standpoint of total particulate stack sampling and particle size analyses. In 2006 and again in 2013, the United States (U.S.) Environmental Protection Agency (EPA) published a more stringent National Ambient Air Quality Standard for particulate matter with nominal diameter less than or equal to 2.5 µm (PM2.5). This created an urgent need to collect additional cotton gin emissions data to address current regulatory issues, because EPA AP-42 cotton gin PM2.5 emission factors were limited. In addition, current EPA AP-42 emission factor quality ratings for cotton gin PM10 (particulate matter with nominal diameter less than or equal to 10 µm) data are questionable, being extremely low. The objective of this study was to characterize particulate emissions for mote trash systems from cotton gins across the cotton belt based on particle size distribution analysis of total particulate samples from EPA-approved stack sampling methods. Average measured of PM2.5, PM6, and PM10 emission factors based on the mass and particle size analyses of EPA Method 17 total particulate filter and wash samples from two gins (6 total test runs) were 0.00031 kg/227-kg bale (0.00068 lb/500-lb bale), 0.0023 kg/bale (0.0051 lb/bale), and 0.0042 kg/bale (0.0093 lb/bale), respectively. The mote trash system particle size distributions were characterized by an average mass median diameter of 23.9 µm (aerodynamic equivalent diameter). Based on system average emission factors, the ratio of PM2.5 to total particulate was 1.75%, PM6 to total particulate was 13.3%, and PM10 to total particulate was 24.2%.

Resumen

Background: Our previous standardized postoperative pain management plan for AIS patients undergoing PSF included the placement of an epidural (EPI) catheter by the spine surgeon prior to fascial closure. The epidural was used for 24 hours, in conjunction with a multi-modal post-operative pain protocol. Local Problem: The 2020 COVID-19 pandemic highlighted the need for our surgical AIS patients and their families to have private rooms/bathrooms. Epidural catheters require arterial line blood pressure monitoring to ensure safety. Unfortunately, the arterial lines could not be utilized in the private rooms due to lack of appropriate monitors, therefore we transitioned away from epidurals. Liposomal bupivacaine (LB) is an encapsulated local anesthetic that has a duration of action up to 72 hours. Specific Aims: This quality initiative (QI) focused on the enhancement of the standardized postoperative care pathway for AIS patients undergoing PSF. The aims of the initiative were to 1) minimize narcotic usage, and 2) allow for earlier mobilization. Intervention: The (2020) LB cohort had a mixture of LB, bupivacaine HCL and normal saline injected into the fascial and subcutaneous layers of the incision prior to fascial closure. The (2019) control cohort had an epidural (EPI) catheter placed prior to fascial closure. The epidural infusion consisted of ropivacaine 0.1% (0.1-0.2 ml/kg/hr.) The cohorts received the same pain protocol (intravenous opioid with transition to oral opioid, as well as dexmedetomidine, acetaminophen, ketorolac, and diazepam). Measures and Analysis: Two cohorts of prospective AIS patients that underwent PSF were retrospectively reviewed. They were compared regarding age, BMI, average preoperative major Cobb angle, average preoperative kyphosis, VAS pain scores and narcotic consumption. Time to ambulation, and length of stay (LOS) were also evaluated. Results: 159 AIS patients were reviewed. There were no preoperative differences between the 2020 LB cohort (n =101) and the 2019 EPI cohort (n = 58) when comparing age (14.3 vs.15.0 years), average BMI (21.7 vs.20.8 kg/m2), preoperative major Cobb (60.7° vs.60.3°), or average preoperative kyphosis (25.7° vs. 27.1°). The LB cohort consumed similar morphine equivalents during the initial 24 hrs. (37.8mg vs.37.3mg), but less at 24-48 hrs. (37.2mg vs 41.0mg) (p=0.031), and 48-72hrs (23.3mg vs. 29.6mg) (p=0.015). The LB cohort ambulated 6.8 hrs. sooner (17.1 vs 23.9 hrs.) (p=.0001). Summary: LB associated with less consumption of post-operative morphine equivalents and earlier ambulation.

Resumen

Abstract BACKGROUND The DNA repair gene ATM is remarkable for its roles across the spectrum of neoplastic biology, including inherited risk of multiple malignancies, somatic tumor biology, and clonal hematopoiesis (CH). We hypothesized that comparison of liquid biopsy (LB) versus tumor tissue (TT) from germline ATM pathogenic mutation carriers (gATM+) might offer additional insights into the role of ATM in CH. METHODS 34,825 LB samples and 384,847 TT specimens were sequenced for up to 324 genes during routine clinical care and analyzed for all classes of genomic alterations (Frampton 2013, Woodhouse 2020). Individual variants were assessed for germline versus somatic origin using the validated somatic-germline zygosity algorithm (Sun 2018). RESULTS Germline ATM mutations were observed in 0.9% (113/12,217) of LB and 0.8% (3,029/384,847) of TT (P<0.001). Up to 27 ATM mutations were identified per gATM+ sample, with a range of 1-27 in LB and 1-8 in TT. Co-occurrence of 3+ ATM mutations in a single sample was 18-fold higher among gATM+ subjects undergoing LB versus TT (23.9% vs. 1.2%, P<0.001). In LB, the incidence of 3+ ATM mutations increased with age for all groups, but the frequency in gATM+ subjects diverged as patient age advanced. In the age 80+ subgroup, 57.1% (28/49) of gATM+ subjects had 3+ ATM mutations, compared to 3.3% (133/4,055) of gATM− subjects (P<0.001). A significant difference was maintained after correcting for the contribution of the germline ATM mutation to the total number of ATM mutations in gATM+ subjects. We hypothesized that multiple ATM variants per sample could be caused by high TMB or positive selection for multiple subclonal hits in the ATM gene. In TT, observation of 3+ ATM mutations was associated with high TMB in 80.5% (513/637) of cases. In contrast, 88.5% (555/627) of LB samples with 3+ ATM mutations had low TMB (Pdiff<0.001), a pattern consistent with positive selection in LB. LB from gATM+ cases with 3+ ATM mutations all had one variant with ~50% variant allele fraction (VAF), while 80.0% (546/682) of the co-mutations had VAF <1%. Co-mutations included 32.0% (793/2,485) truncating alterations and 68.1% (1,692/2,485) missense alterations. Low VAF missense co-mutations were clustered in the FAT and PIKKc domains, which are known pathogenic missense mutation hotspots. This distribution suggests that some missense alterations within these hotspots that are currently classified as VUS are under positive selection and therefore warrant consideration for reclassification. CONCLUSION The finding of numerous ATM mutations under positive selection in gATM+ subjects was specific to LB, increased in incidence with age, and co-mutations tended to have low VAF. All these features are consistent with polyclonal hematopoiesis (polyCH) involving ATM co-mutations in gATM+ subjects. Additional investigation is needed to extend our understanding of this phenomenon. Citation Format: Brennan Decker, Angela A. Kou, Tyler Janovitz, Douglas A. Mata, Ethan S. Sokol, Dexter X.

Resumen

During the last decade, Europe was confronted with the emergence of two Culicoides-borne viruses, bluetongue virus and Schmallenberg virus. Both diseases caused economic losses in cattle, sheep, and goats. Despite their importance, only limited knowledge is available on the developmental stages of Culicoides obsoletus complex midges, and a lab-reared colony has not yet been established. Therefore, this experimental study aims to compare the emergence patterns from field-collected C. obsoletus complex from egg to adult that were exposed to different combinations of temperature and larval substrates (T1: 1% liquid broth (LB) agar at 24 °C; T2: 1% LB agar with dung patches at 24 °C; T3: 1% LB agar at 28 °C). The rearing dishes were kept in an environmental chamber under an 8 h/16 h dark–light regime and 80%–85% humidity. Algae and nematodes were provided as a food source. The average period required to develop from egg to adult was 24 days and varied strongly in each of the conditions (T1: 15–47 days; T2: 14–35 days; T3: 20–37 days). A bias of sex ratio was observed towards the production of males in all three treatments with only 23.9% (T1), 23.5% (T2), and 0% (T3) females. Larval mortality was highest in T3 (25.9%), followed by T2 (8.6%), and T1 (1.8%). All pupae produced adults within 1 to 10 days, and the emergence rates for pupae varied strongly between treatments: 49.5% (T1), 71.6% (T2), and 38.5% (T3). This study shows that the C. obsoletus complex can be reared under laboratory conditions from blood-fed, wild-caught females to emerged progeny. More larval substrates and food sources should be tested with the aim of obtaining a 1:1 sex ratio to bring us one step closer to a viable lab-reared colony.

Resumen

In 2009, the Manual for Assessing Safety Hardware (MASH) was adopted as an updated replacement of NCHRP Report 350. Under MASH, the impact severity of Test Level 4 (TL-4) (Test 4–12) was increased by 56%. Test vehicle mass was increased from 17,640 to 22,050 lb. Impact speed was increased from 50 to 56 mph. Although this is a significant increase in the amount of lateral energy imparted to the barrier, the 54-kip design impact load currently suggested by the AASHTO load and resistance factor design (LRFD) bridge specifications has not been updated to meet MASH TL-4 requirements. Similarly, the AASHTO LRFD specifications require all TL-4 railings to have a minimum height of 32 in. However, because of the increase in test vehicle mass and impact velocity under MASH, the minimum height for TL-4 railings is expected to be greater than 32 in. This height was verified by a recent unsuccessful MASH Test 4–12 of a New Jersey profile rigid concrete barrier 32 in. tall. The research presented in this paper used finite element analysis and subsequent crash testing to determine the minimum rail height for MASH TL-4 impact conditions. The researchers also determined the appropriate lateral impact design load for use with AASHTO LRFD bridge specifications for the design of TL-4 bridge rails.

Resumen

Abstract The Southeast (SE) Hay Contest was started by a group of Extension agents from across the SE with the objective of increasing producer knowledge of the relative forage quality (RFQ) index. Since its inception, the program has grown to over 350 hay and baleage samples annually. Forage samples were categorized into warm-season perennial grass hay (WSPGH), alfalfa hay (AH), perennial peanut hay (PPH), cool-season perennial grass hay (CSPGH), mixed annual grass, or other hay (MAG), grass baleage (GB), and legume baleage (LB). Samples were analyzed for RFQ and crude protein (CP) using near infrared reflectance spectroscopy (NIRS) at the UGA Forage Testing Center (Athens, GA). The following summary includes data from 2009–2018 analyzed using Proc Glimmix of SAS 9.4 (SAS Inst., Cary, NC) with category and year as fixed effects and α = 0.05. Alfalfa hay had the greatest RFQ, followed by LB (P ≤ 0.004; 199 and 186, respectively). Perennial peanut and GB had median RFQ values (P ≤ 0.001; 169 and 150, respectively), and WSPGH had the least (P ≤ 0.008; 117). With the exception of 2017, the years 2013 to 2018 had the greatest RFQ (P < 0.001; 165). 2017 had a greater amount of rain than average, likely resulting in its lower average RFQ. Alfalfa hay had the greatest (P < 0.001) CP of all categories (23.9%; P < 0.001). Crude protein concentrations did not differ among WSPGH, CSPGJH, and MAG (P ≥ 0.192; 14.5%). While these forage samples were likely greater quality than samples not submitted, we conclude that outreach efforts, including the SE Hay Contest, have increased knowledge of the hay and baleage production process leading to increased hay quality from 2009 to 2018.

Resumen

Background: Lymphadenopathy refers to one or more lymph nodes that are abnormal in size, consistency or number. There are various causes for lymphadenopathy which range from benign conditions to malignant either primary or secondary from draining primary tumour. Lymphadenopathy can be localised to a single group or generalised.Methods: Prospective observational study was performed for the patients attending outpatient department of general surgery at Kamineni academy of medical sciences, LB nagar Hyderabad, Telangana with complaints of enlarged or swollen lymph nodes in the neck. This study included 46 cases. In cases where fine needle aspiration cytology was inconclusive and there was need for excision biopsy, only these cases were included in the study. After biopsy lymph node was sent for gross and microscopic examination for expert opinion from department of pathology.Results: The present study includes 46 patients in a period of two years from 01-8-2015 to 31-7-2017. Of these case tuberculosis lymphadenopathy (n=25,54.3%) was the most common aetiology followed by nonspecific chronic lymphadenopathy (n=16,34.7%) followed by some relatively rare cases and unusual presentation Schwannoma, pleomorphic adenoma, Kikuchi disease, non-Hodgkin’s lymphoma and secondaries from carcinoma tongue (n=1,2.1%).Conclusions: In the present prospective study tubercular lymphadenopathy was the most common cause for cervical lymphadenopathy followed by chronic nonspecific lymphadenopathy.

Resumen

Background: Umbilical hernias can cause distress to the patients not only because of their complications but also because of the cosmetic angle, therefore this study was undertaken mainly to study the outcomes of preperitoneal mesh repair and on-lay mesh repair in the management of umbilical hernias.Methods: The present study was a prospective, observational and comparative study undertaken in the department of general surgery, who had been operated in Kamineni hospital LB Nagar, Hyderabad, Telangana, during a study period from November-2020 to September-2021.Results: Of 30 patients who underwent on-lay mesh repair, the mean hospital stay was 3.83±1.8 days; wound infection, seroma, hematoma, flap necrosis was seen in 1, 4, 2, 1 respectively and with no recurrence in 6 months follow-up. Of 30 patients who underwent pre-peritoneal mesh repair, the mean hospital stay was 2.13±0.63 days; Wound infection, seroma, hematoma, flap necrosis was seen in 0, 2, 1, 0 respectively and with no recurrence in 6 months follow-up.Conclusions: On-lay mesh repair can be replaced with preperitoneal mesh repair. Overall mesh related complications, including wound infection, seroma, hematoma, flap necrosis is quite rare. Less Hospital stay and low recurrence rate was observed in preperitoneal method. As wound complication increases risk of recurrence, procedures that do not result in formation of de-vascularizing flaps may be recommended.

Resumen

The aim of this study is to evaluate the Turkish Language Teaching Program for Foreigners at Minsk State Linguistic University in Belarus. The study aims to answer the following two main questions: 1) what are the discrepancies between the current status and the desired outcomes of the Turkish program at MSLU? 2) What aspects of the Turkish program should be maintained, strengthened or added? In order to answer these questions, data were collected from students who were attending the program in the 2002-2003 academic year, instructors who were teaching in the program in the same academic year, the graduates of the program, former instructors of this program, the parents of the students who were currently attending the program, the authorities at the institution, the employers of the graduates of this program in Minsk. Both qualitative and quantitative data were collected in the study. The quantitative data were collected through questionnaires. The qualitative data were collected through interviews and written document analysis. The results of the data showed that the Turkish Language Program at Minsk State Linguistic University partially meets the needs and demands of all the involved parties. However, it was observed that enthusiasm and interest for the Turkish language among the current students, graduates and the University authorities were high. Some changes and additions could be made in the program to make it better suited to the needs and demands of its under goers and institution.

, Ferda M.S. Department of Educational Sciences Supervisor: Assoc. Prof. Dr. Cennet Engin DEMiR January 2010, 110 pages This study aimed to evaluate the effectiveness of Ankara University Preparatory School program through the perspectives of instructors and students. To this end, the CIPP (context, input, process, and product) evaluation model developed by Stufflebeam (1971) was utilized. 406 students attending the preparatory school in the 2008-2009 academic year and 12 instructors teaching in the program participated in the study. The data were gathered through a self-reported student questionnaire and an interview schedule which was designed for the instructors. Besides, in order to obtain more detailed information about the preparatory school, written documents were examined. While the data based on the questionnaire were analyzed through descriptive and inferential statistics, content analysis was carried out to analyze the qualitative data. Multivariate Analysis of Variances with Pillai&rsquo
s Trace test was employed to investigate whether the significant differences among dependent variables across independent variables existed. Results of the study indicated that the program at Ankara University Preparatory School partially served for its purpose. The findings revealed that some improvements in the physical conditions, content, materials and assessment dimensions of the program were required to make the program more effective.

Resumen

This study examined the impact of learner-centered teaching and learning process on pre-advanced first year medical students&rsquo
performance, attitudes, and retention in medical English through a pre-test/post-test experimental research design.The sample of this study included 180 first year medical students of a state medical university, Gazi University, Medical Faculty, Ankara, Turkey. The subjects were assigned to experimental and control groups. Before the experiment, an achievement test and an attitude test were given as pre-test to both groups. The subjects in the control group (n=90) continued with traditional instruction while the subjects in the experimental group (n=90) studied using the learner-centered instruction. The treatment lasted 14 weeks. At the end of the treatment, the same achievement and the attitude tests were given as post-tests. One month after the post-test, the same achievement test was given to both groups as retention test.The post-test results of the study indicate no statistically significant difference between the control and experimental groups immediately after the experiment. However, retention test results show significant difference between the two groups in favor of the experimental group. The attitude post test results toward the experimental instruction show significant difference between the two groups in favor of the experimental group as well.

interest questionnaire, were developed by the researcher. These instruments were implemented on 75 English language learners studying at TOBB ETU Preparatory School. The results obtained from the instruments were analyzed through SPSS 15.0. In analyzing the data, descriptive statistics as average and standard deviation besides inferential statistics as one-way ANOVA and Spearman&rsquo
s correlation test were used. The results of the study revealed that there is a significant difference among the three reading performance scores of the language learners. Besides, the correlation of topic background knowledge and interest is highlighted for each of three reading comprehension tests, so are the significant relationships of (a) background knowledge and reading performance as well (b) topic interest and reading performance also among the results for the moderate-interest &
background knowledge and high- interest &
background knowledge tests.

ABSTRACT COMPARISON OF 2002 AND 2004 ELEMENTARY SCIENCE CURRICULA WITH RESPECT TO COGNITIVE AND AFFECTIVE CHARACTERISTICS OF STUDENTS Oruç
, Akif M.S., Department of Secondary Science and Mathematics Education Supervisor: Prof. Dr. Giray Berberoglu June 2009, 116 pages The purpose of this study is to investigate the effect of 2004 elementary science and technology curricula at grade level 7. For this purpose, the effect of 2004 curricula on the (1) achievement of the students in knowledge, conceptual understanding and higher order thinking skills clusters, (2) attitude toward science and technology, (3) teachers&rsquo
classroom activities were evaluated. This study was conducted on 290 7th grade students at six elementary schools in 2006-2007 spring term. These schools were located in Sincan, Yenimahalle and Mamak in Ankara. Two schools were administering 2004 curricula as pilot group and four of them were teaching science with 2002 curricula. Grade level 7 was selected for the study since both 2002 and 2004 curricula were being implemented in the schools only at this particular grade level. The achievement test questions were selected from TIMMS science achievement tests and the researcher&rsquo
s own questions written in line with the test plan. The questions include the common objectives of both 2002 and 2004 curricula. The Test of Science Related Attitudes was developed by Chaerul (2002). As a result of the factor analysis it was decided that, the scale contains five sub categories: Social implication of science, Scientist lifestyle, Enjoyment of learning in science lesson, Leisure interest in science, and Career interest in science. Teachers&rsquo
Classroom Activities Scale was taken from Pekiner (2007). It was decided that, the scale contains five sub categories
New Approach, Care of Teacher, Use of Equipment by teachers, Classical Classroom Activities and Processing the Subject category. The data were analyzed by using multivariate analysis of variance (MANOVA). The results of this analyses indicated no major difference between two science curricula. On the other hand, significant differences were found in leisure interest of students and use of equipment by teachers in favor of 2004 curricula. Knowledge and conceptual understanding level learning, the enjoyment of learning in science lesson and teachers&rsquo
classroom activities with reference to new approaches indicated significant results in favor of 2002 curricula.

Resumen

This study aimed to conduct an evaluation based on stakeholders&rsquo
perceptions of the effectiveness of the English Language Teaching Program at Atilim University, Preparatory School. Moreover, the study wanted to find out to what extent the program meets students&rsquo
expectations and whether there are any differences in stakeholders&rsquo
perceptions with regard to their ideal language teaching-learning environment and their real (classroom) practices. The sample included 62 instructors, including three administrators, and a teacher trainer and 216 students attending Prep. School in the academic term of 2008-2009. The data were collected through two questionnaires, developed by the researcher: one was designed for instructors and administrators
the other was designed for students. To support the close-ended items in the questionnaires, each questionnaire included some open-ended items. Data based on the questionnaires were analyzed through descriptive statistics. While, the qualitative data were analyzed through content analysis. Lastly, to validate the data and increase the credibility of the data, triangulation procedure was carried out. The findings of the study showed that the program at Atilim University Prep. School needs some improvements in the following areas: (1) the goals and objectives need to be clearly identified
(2) the content of the instruction needs to include all language skills
(3) the resources and materials need to be revised in terms of their content and compatibility with the goals of the school, and the proficiency exam
(4) the goals and the content of the testing means, especially proficiency exam, need to be redefined and made compatible with the content of the books and instruction.

Resumen

This study examines the implementation of the theme-based curriculum in the 2003-2004 academic year to meet the goals and objectives of DBE students at METU. The research design of the study includes questionnaires and focus group interviews with former DBE students and DBE teachers. At the first stage, 231 students and 60 teachers took the questionnaire. Then, 19 students (in groups) and teachers (individually) were interviewed. The results indicated that there was a big difference between the perceptions of teachers and students and teachers were more negative about the program. Especially, pre-intermediate group teachers were quite dissatisfied with the program. Implementation and quality of the materials and lack of communication between teachers and administrators were considered as probable reasons. In terms of materials, reading was the skill most successfully developed. Moreover, students found handouts much more useful than the books. Writing seemed to be the most problematic area in the program. Finally, as a result of time limitation, teachers were perceived to be more active in class and pair/group work were considered as ineffective.

Resumen

Abstract The presence of formation water under strong water drive will support the oil production in the early life of the well then will become an issue, which is difficult to control with time. With the need of sustain and increase oil production in North Kuwait year after year, it become impassable to keep producing oil wells with low rate and rate below critical coning rate. Using Chaperone method calculation, the critical coning rate require for lower Burgan is ± 300 BLPD, to avoid coning LB well should be produce with rate less than 300 BOPD. With the high target oil rate required from NK, it is impossible to produce wells with rate below 300 BLPD. Coning control completion (CCC) is a new technology that have been used in NK to control the coning issue in Lower Burgan, the completion contain a reverse ESP located below the oil water contact (OWC). Reverse ESP will create a counteractive pressure drawdown below the OWC to control the progression of the water cone within the oil zone. The reverse ESP will take the water below the OWC of the target zone, dump water into under-lying reservoir to minimize produced water at surface. CCC have helped NK to reduce WC from 90% to 30%. Coning has always been an uncontrolled issue in lower Burgan, with the high pressure in LB all wells produce naturally with low WC with time coning rise-causing WC to reach 80-90%. With the increase of WC the well can't produce naturally, and it need an ESP to lift the fluid, with ESP the conning increases causing WC to increase more than 90%. CCC have helped to in reduce excessive produced water on the gathering centers and improve the Recovery Factor in partial and strong water drive Reservoirs by reducing the coning effect. This paper will discuss the mechanism, application and the successful result of using CCC in NK and how implementing this new type of completion helped NK to improve lower Burgan reservoir.

Resumen

This research project was performed in context of the apparent probiotic effect of selected lactic acid bacteria (LAB) silage inoculants on the performance of ruminants (improved feed intake, faster live-weight gain, higher milk yields and improved feed efficiency). The overall objective was to find out how LAB affect ruminant performance. The project included several “chapters” as follows: 1. The effect of LAB silage inoculants on the survival of detrimental bacteria in rumen fluid, in vitro study (Weinberg et al., The Volcani Center). An in vitro model was developed to study the interaction between selected LAB and an E. coli strain tagged with green fluorescence protein (GFP) in buffered RF. Results indicated that both LAB inoculants and E. coli survived in the RF for several days; both LAB inoculants and LAB-treated silages did not affect survival of E. coli in rumen fluid in vitro. The effect of feeding baled wheat silages treated with or without three selected LAB silage inoculants on the performance of high-lactating cows (Weinberg et al., The Volcani Center). Treatments included control (no additive), Lacobacillusbuchneri40788 (LB), Lactobacillus plantarumMTD1 40027 (LP) and Pediococcuspentosaceus30168 (PP), each applied at 10⁶ cfu/g FM. The silages were included in the TMR of 32 high milking Holstein cows in a controlled feeding experiment. All baled silages were of good quality. The LB silage had the numerically highest acetic acid and were the most stable upon aerobic exposure. The cows fed the LB silages had the highest daily milk yields, percent milk fat and protein. The microbiome of baled wheat silages and changes during ensiling of wheat and corn (Sela et al., The Volcani Center). Bacterial community of the baled silages was dominated mainly of two genera in total, dominated by Lactobacillus and Clostridium_sensu_stricto_12 with 300 other genera at very low abundance. Fungal community was composed mainly of two genera in total, dominated by Candida and Monascuswith 20 other genera at very low abundance. In addition, changes in the microbiome during ensiling of wheat and corn with and without addition of L. plantarumMTD1 was studied in mini-silos. Overall 236 bacterial genera were identified in the fresh corn but after 3 months Lactobacillus outnumbered all other species by acquiring 95% of relative abundance. The wheat silage samples are still under analysis. The effect of applying LAB inoculants at ensiling on survival of E. coli O157:H7 in alfalfa and corn silages(Adesogan et al., University of Florida). E. coli (10⁵ cfu/g) was applied to fresh alfalfa and corn at ensiling with or without L. plantarumor L. buchneri. The pathogen was added again after about 3 moths at the beginning of an aerobic exposure period. The inoculants resulted in faster decrease in pH as compared with the control (no additives) or E. coli alone and therefore, the pathogen was eliminated faster from these silages. After aerobic exposure the pathogen was not detected in the LAB treated silages, whereas it was still present in the E. coli alone samples. 5. The effect of feeding corn silage treated with or without L. buchnerion shedding of E. coli O157:H7 by dairy cows (Adesogan et al., UFL). BARD Report - Project 4704 Page 2 of 12 Five hundred cows from the dairy herd of the University of Florida were screened for E. coli shedding, out of which 14 low and 13 high shedders were selected. These cows were fed a total mixed ration (TMR) which was inoculated with E. coli O157:H7 for 21 days. The TMR included corn silage treated with or without L. buchneri. The inoculated silages were more stable upon aerobic exposure than the control silages; the silage inoculant had no significant effect on any milk or cow blood parameters. However, the silage inoculant tended to reduce shedding of E. coli regardless of high or low shedders (p = 0.06). 6. The effect of feeding baled wheat silages treated with or without three selected LAB silage inoculants on the rumen microbiome (Mizrahi et al., BGU). Rumen fluid was sampled throughout the feeding experiment in which inoculated wheat silages were included in the rations. Microbial DNA was subsequently purified from each sample and the 16S rRNA was sequenced, thus obtaining an overview of the microbiome and its dynamic changes for each experimental treatment. We observed an increase in OTU richness in the group which received the baled silage inoculated with Lactobacillus Plantarum(LP). In contrast the group fed Lactobacillus buchneri(LB) inoculated silage resulted in a significant decrease in richness. Lower OTU richness was recently associated in lactating cows with higher performance (Ben Shabatet al., 2016). No significant clustering could be observed between the different inoculation treatments and the control in non metric multi-dimentional scaling, suggesting that the effect of the treatments is not the result of an overall modulation of the microbiome composition but possibly the result of more discrete interactions. Significant phylum level changes in composition also indicates that no broad changes in taxa identity and composition occurred under any treatment A more discrete modulation could be observed in the fold change of several taxonomic groups (genus level analysis), unique to each treatment, before and after the treatment. Of particular interest is the LB treated group, in which several taxa significantly decreased in abundance. BARD Report - Project 4704 Page 3 of 12
