Abstract:

Despite the important role of antimicrobial use in companion animals in the global challenge presented by antimicrobial resistance (AMR), very few studies have quantified pet owner factors that can contribute to suboptimal veterinary antimicrobial use. We conducted an online survey of pet owners, asking about their experiences with veterinarians, their opinions on antibiotic use and knowledge of antibiotics, and their communication preferences regarding judicious prescribing. Just over half (54%) of the 558 pet owners had received antibiotics for their pet at their last non-routine veterinary consultation and most owners were happy (83%) with the antibiotic prescribing decision of their veterinarian. A quarter (25%) indicated that they had been surprised, disappointed or frustrated when a veterinarian had not given their pet antibiotics; 15% had explicitly requested them. Owners placed a higher priority on their pet receiving the most effective treatment than on treatment being cheap or convenient. Most respondents recognized the limitations of antibiotic therapy and the risks associated with antibiotic use, but 50% believed the risks were confined to the treated animal; only a minority was aware of inter-species transfer of bacteria. Pet owners indicated that they would find judicious prescribing messages focused on the direct risks of antibiotics to their pet more compelling than those about public health. Our findings suggest that veterinary communications about responsible antibiotic use should focus on pet owners’ priorities and address or bypass their gaps in understanding regarding antibiotic resistance.

Abstract:

The phenomenon of antibiotic resistance is a global problem that affects the use of antibiotics by humans and animal husbandry. One of the primary reasons for the growing phenomenon of antibiotic resistance is the over-prescription of antibiotics by doctors in human medicine and the overuse of antibiotics in industrial animal farming. Adequate education of veterinary medical students on the use of antibiotics in animal husbandry may reduce antibiotic resistance. For this reason, a survey was conducted among students at four primary research and didactic centers teaching veterinary medicine in Poland. The survey aimed to find out the knowledge and attitude of students towards the use of antibiotics and antibiotic resistance. The survey was conducted in May/June 2021. Four hundred and sixty-seven students participated in the study. The study positively verified that antibiotics and antibiotic resistance knowledge increase with successive years of veterinary studies/education. For most students (82.2%), antibiotic resistance is a significant problem, but only 58.7% believe it is global, and one in three respondents heard about the One Health approach.

Abstract:

Antimicrobial resistance (AMR) is an urgent and complex problem worldwide, exacerbated by the frequently inappropriate use of antibiotics. The purpose of this study was to survey the levels of knowledge and awareness about antibiotic use and stewardship, among human and veterinary health professionals or students in Portugal, and the associations between antibiotic knowledge factors and socio-professional groups. In cross-sectional survey design, a total of 449 online structured questionnaires were completed in 2018–2019. The statistical analysis was performed dividing the respondents into four groups, A (undergraduate students), B (PhD students and researchers), C (lecturers), and D (technicians and other occupation). Among all respondents, 17% (n = 75) revealed some gap in knowledge about antibiotic resistance and the antibiotics that should be administered for different infection types (bacterial, viral, or fungal). Of the 159 pet owners among the respondents, only half had administered antibiotics to their animal and 64% (n = 102) knew that veterinary prescription is mandatory when administering antibiotics to animals. All groups statistically agreed that the AMR is a major public health problem and the antibiotics should be administrated for bacterial infections and used until the whole pack has been finished (p = 0.00). As expected, only groups B and C demonstrated a higher level of knowledge to recognize the antibiotic name and their active ingredient than undergraduate students (p = 0.00). About the antibiotic use on pets, only group B was statistically significant to no used antibiotics on their pets (p = 0.00). However, groups A, C, and D were statistically significant for the knowledge about the mandatory veterinarian prescription and groups C and D were significantly statistics for fully aware of the transmission of bacteria between animals and humans. In conclusion, in matters related to AMR, the behavior, education, and training of the general public and health professionals, including those who prescribe antibiotics for humans and animals, need to be improved.

Abstract:

Use of low dose, prophylactic antibiotics contributes to the emergence of antibiotic resistant bacteria. In one study, goat meat in Missouri was found to have a higher percentage of antibiotic residues at slaughter than the national average, so we attempted to identify factors related to goat production that may contribute to this issue. Using the knowledge, attitude, and behavior (KAB) model, we interviewed 11 Missouri goat farmers about factors affecting antibiotic use. Most of the farmers did not have specific protocols for managing illnesses and only relied on veterinarians for major health issues. Many felt veterinarians lacked knowledge about goat medicine so instead relied on other farmers’ or their own experiences for treatment modalities. While most agreed that antibiotic resistance was a concern, only 4 of the 11 indicated that they only used antibiotics when prescribed by the veterinarian. Veterinarians should be relied on and valued for their medical expertise, but they are not always being utilized in this manner. Therefore, veterinary education should emphasize goat health management to a greater extent than it currently does, and soft skills to build collaborative relationships with farmers should be taught to promote preventative health measures and more judicious use of antibiotics.

Abstract:

Une enquête transversale a été faite pour évaluer l’utilisation des antibiotiques dans les élevages de production de lait de vache des communes de Natitingou, Kérou, Pehunco, Kouandé et Djougou au nord-ouest du Bénin. Sur 452 éleveurs enquêtés, 347 (76,7%) utilisaient des antibiotiques sans assistance vétérinaire pour le traitement des affections respiratoires (19,0%), les entérites néo natales (19,0%), les dermatoses (18,0%), les plaies (17,0%), les mammites (17,0%) ou d’autres maladies (10,0%). Les tétracyclines (100,0%), les pénicillines (100,0%), les sulfamides (47,1%) et les macrolides (16,8%) étaient les familles d’antibiotiques les plus utilisées. 35,6% des éleveurs achetait les antibiotiques au marché contre 84,4% chez un vétérinaire et 35,1% les achetait sans le conseil d’un vétérinaire. Plus de 50% des éleveurs ne consulte pas un vétérinaire pour l’administration des antibiotiques ou n’adapte jamais la posologie selon le poids des bovins traités. Enfin, 83,6% des éleveurs faisaient traire les vaches sous traitement antibiotiques tout comme les vaches sans traitement. Les services vétérinaires du Bénin devraient mieux contrôler de l’utilisation des antibiotiques en production de lait de vache et sensibiliser les éleveurs sur le risque représenté par la présence de résidus d’antibiotiques dans le lait de vache consommé. ABSTRACT A cross sectional survey was conducted to assess the use of antibiotic in dairy farms in the municipalities of Natitingou, Kérou, Pehunco, Kouandé and Djougou in northwestern Benin. Three hundred and Forty seven 347 (76.7%) of the 452 surveyed farmers used antibiotics without veterinary assistance against neonatal enteritis (19.0%), dermatitis (18.0%), wounds (17.0%), mastitis (17.0%) or others diseases (10.0%). Tetracyclines (100.0%), penicillins (100.0%), sulfonamides (47.1%) and macrolides (16.8 %) and were the most used families of antibiotics. 35.6% of breeders bought antibiotics at the market against 84.4% at a veterinarian and 35.1% bought them without the advice of a veterinarian. More than 50% of breeders do not consult a veterinarian for the administration of antibiotics or never adapt the dosage according to the weight of the treated cattle. Finally, 83.6% of breeders milked cows under antibiotic treatment as cows without treatment. Benin veterinary services should more control the use of antibiotics in dairy farms and inform the farmer about the risk associated with the presence of antibiotics residues in consumed cow milk.

Abstract:

Small-scale food animal production has been celebrated as a means of economic mobility and improved food security but the use of veterinary antibiotics among these producers may be contributing to the spread of antibiotic resistance in animals and humans. In order to improve antibiotic stewardship in this sector, it is critical to identify the drivers of producers’ antibiotic use. This study assessed the determinants of antibiotic use in small-scale food animal production through simulated client visits to veterinary supply stores and surveys with households that owned food animals (n = 117) in Ecuador. Eighty percent of households with food animals owned chickens and 78% of those with chickens owned fewer than 10 birds. Among the households with small-scale food animals, 21% reported giving antibiotics to their food animals within the last six months. Simulated client visits indicated that veterinary sales agents frequently recommended inappropriate antibiotic use, as 66% of sales agents recommended growth promoting antibiotics, and 48% of sales agents recommended an antibiotic that was an inappropriate class for disease treatment. In contrast, few sales agents (3%) were willing to sell colistin, an antibiotic banned for veterinary use in Ecuador as of January 2020, which supports the effectiveness of government regulation in antibiotic stewardship. The cumulative evidence provided by this study indicates that veterinary sales agents play an active role in promoting indiscriminate and inappropriate use of antibiotics in small-scale food animal production.

Abstract:

Objectives The aim of this study was to explore owners’ knowledge of antibiotics, experience of antibiotic use in their cats and involvement in decision-making regarding antibiotic prescriptions. Methods Cat owners were recruited via social media and veterinary practices to complete a survey designed to evaluate general knowledge of antibiotics, attitudes to antibiotic stewardship and experiences of antibiotic use in their own cat between November 2017 and March 2018. Data were analysed descriptively. Results A total of 1436 surveys were completed; 247 respondents (17.2%) had a veterinary background. The majority of the remaining respondents correctly identified that antibiotics treat bacterial infections (84.0%; n = 999) but do not treat viral infections (72.8%; n = 865). A minority (n = 338; 28.4%) agreed that antibiotic resistance was a problem in cats in the UK; 92.3% (n = 1097) identified that resistance was a problem in human medicine. Seventy percent (n = 832) of the respondents’ cats had received antibiotics; 29.6% (n = 246) received a long-acting injectable antibiotic (14 days’ duration). Diagnostic tests were performed before antibiotic prescription in 38.7% (n = 322) of cats; 1.4% (n = 7) of respondents reported declining suggested tests and 65.8% (n = 778) indicated that they would be happy to pay for diagnostic tests to allow selection of the most appropriate antibiotic. Most respondents (95.8%; n = 792) indicated that they were happy to follow their veterinarian’s advice and recommendations; however, 49.2% (n = 405) had expected antibiotics to be prescribed. Conclusions and relevance Cat owners demonstrated good knowledge of antibiotic action; however, greater owner education regarding the potential for veterinary antibiotic resistance, requirement for diagnostic testing and training in the administration of oral medication with first-line antibiotics, as well as the use of veterinary antibiotic guidelines, will improve antibiotic stewardship. Good communication between veterinarians and owners is necessary for rational antibiotic use.

Abstract:

Smallholder farms are the predominant livestock system in India. Animals are often kept in close contact with household members, and access to veterinary services is limited. However, limited research exists on how antibiotics are used in smallholder livestock in India. We investigated antibiotic supply, usage, and their drivers in smallholder livestock production systems, including crossover-use of human and veterinary antibiotics in two rural sites in West Bengal. Qualitative interviews were conducted with key informants (n = 9), livestock keepers (n = 37), and formal and informal antibiotic providers from veterinary and human health sectors (n = 26). Data were analysed thematically and interpreted following a One Health approach. Livestock keepers and providers used antibiotics predominantly for treating individual animals, and for disease prevention in poultry but not for growth promotion. All providers used (highest priority) critically important antimicrobials for human health and engaged in crossover-use of human antibiotic formulations in livestock. Inadequate access to veterinary drugs and services, and a perceived efficacy and ease of dosing of human antibiotics in animals drove crossover-use. Veterinary antibiotics were not used for human health due to their perceived adverse effects. Given the extent of usage of protected antibiotics and crossover-use, interventions at the community level should adopt a One Health approach that considers all antibiotic providers and livestock keepers and prioritizes the development of evidence-based guidelines to promote responsible use of antibiotics in animals.

Abstract:

The complex issue of antibacterial resistance (ABR) requires actions taken with the One Health approach, involving both human and veterinarian medicine. It can spread from animals to humans through the food chain or through direct contact. Health profession students, as the future antibiotic providers, can greatly impact antibiotic-related issues in the future. The study was conducted to evaluate knowledge, attitudes and practice of future antibiotic prescribers in relation to judicious use of antibiotics. This cross-sectional, questionnaire-based study was performed on 400 students of health professions who were allowed to prescribe antibiotics of the University of Novi Sad, Serbia. Students of medicine and students of dentistry showed a significantly higher knowledge score compared to students of veterinary medicine (p = 0.001). Multivariate regression identified predictors of adequate antibiotic knowledge: being a female student (B = 0.571; p = 0.020), higher grade average (B = 1.204; p = 0.001), students of medicine (B = 0.802; p = 0.006) and dentistry (B = 0.769; p = 0.026), and students who used a complete package of antibiotics during the last infection (B = 0.974; p = 0.001) or for the period recommended by the doctor (B = 1.964; p = 0.001). Out of the total sample, self-medication was reported among 42.8% of students. The identified predictors of self-medication were: more frequent (B = 0.587; p = 0.001) and irregular (B = 0.719; p = 0.007) antibiotic use, taking antibiotics until symptoms disappeared (B = 2.142; p = 0.001) or until the bottle was finished (B = 1.010; p = 0.001) during the last infection. It seems prudent to reevaluate the educational curricula regarding antibiotic use and ABR of prospective prescribers in Serbia.

Abstract:

Widespread use of antibiotics in U.S. livestock operations has been identified as a potential contributor to the rising rates of antibiotic-resistant bacterial infections. In response, the U.S. Food and Drug Administration (FDA) issued new rules in January 2017. GFI (Guide for Industry) #213 banned use of antibiotics for growth promotion and required veterinarian permission, via a revised Veterinary Feed Directive (VFD), to deliver antibiotics through feed. Many stakeholders expressed pre-implementation concerns regarding the rules’ potential adverse effects on production and profitability. Our study employed qualitative and quantitative methods to investigate how implementation of GFI #213/VFD impacted Ohio cattle operations. We interviewed over fifty cattle farmers and eight large animal veterinarians to document changes in farm antibiotic use, management practices, and profitability. We also examined published government data for possible effects on overall meat production at the state and national levels. We found that the great majority of Ohio farmers reported little difficulty in complying with the VFD with minimal adverse impacts. Farm responses to the feed directive varied with operation size, type (beef or dairy), and whether producers had previously used fed antibiotics. The most commonly reported changes, by both producers and veterinarians, were more veterinary-client interactions, more paperwork/record-keeping, and decreased use of fed antibiotics. All veterinarians, many beef operators, but no dairy operators reported perceiving the VFD as beneficial; however, dairy operations reported less difficulty with compliance due to established working relationships with veterinarians. We found no evidence that the rules impacted the trajectory of state or national livestock output. In conclusion, GFI #213 was reported as not burdensome enough to prevent compliance, but inconvenient enough to incentivize reduced use of fed antibiotics (when previously used) without significant adverse effects, consistent with its goal of promoting judicious use of medically important antibiotics in order to preserve their effectiveness.

In the upper Midwest, subsurface tile drainage water is a major contributor of nitrate (NO[subscript]3–N) coming from fertilizers and animal manure. Movement of NO[subscript]3-N through tile drainage into streams is a major concern as it can cause eutrophication and hypoxia conditions, as in the Gulf of Mexico. Denitrifying bioreactors is one of the pollution control strategies to treat contaminated tile drainage water. These bioreactors require four conditions which are: 1) organic carbon source, 2) anaerobic conditions, 3) denitrifying bacteria and 4) influent NO[subscript]3-N. This research focuses on investigating fate of veterinary antibiotics in woodchips commonly used in in-situ reactors. Tylosin (TYL) and sulfamethazine (SMZ) are two veterinary antibiotics which are most commonly used in the United States and can be found in tile water after manure is land applied. Partition coefficients of TYL and SMZ on wood were determined by sorption experiments using fresh woodchips and woodchips from an in situ reactor. It was concluded that the woodchips were an effective means to sorb the veterinary antibiotics leached into the tile water after application of animal manure. Linear partition coefficients were calculated and phase distribution relationships were established for both the chemicals. The fresh woodchips gave inconclusive data but predictions could be made by the information determined in the experiments using woodchips from a ten year old woodchip bioreactor. Desorption was also studied and the likelihood of desorption was predicted using the Apparent Hysteresis Index. Overall, it was found that the old woodchips allowed for quick sorption of both antibiotics. It was also found that SMZ had reversible sorption on old woodchips. Thus, it was concluded that the woodchip bioreactor would not be effective for removal of veterinary antibiotics from tile drainage. More research is required for the fate of TYL and to confirm the conclusion.

The objective of this study was to evaluate the prevalence of Salmonella spp. and their antibiotic resistance profiles in swine slaughtered in abattoirs under federal inspection located in the state of São Paulo. For both types of samples, such as feces and mediastinal, mesenteric and submandibular lymph nodes, 50 samples of each type being possible to evaluate the relevance of the type of material analyzed in relation to the actual status of the animal against the contamination by the pathogen were used. Based on positive samples, serotyping of the strains and antibiotic resistance test was performed. The prevalence of the pathogen was 10% of total samples (20/200) wich the highest positivity found in the submandibular lymph nodes with 20% positive (10/50) and mesenteric with 18% (9/50) and lower found in the feces with 2% positive (1/50) and mediastinal lymph nodes with no positive sample. The predominant serotypes were S.Typhimurium with 55% of the samples (11/20) followed by S. enterica subspecies enterica 4,5,12: i: -, 35% (7/20) and the serotypes S. Brandenburg and S. derby 5% (1/20) each. All isolates were resistant at least one of the antimicrobials tested, among them 90% (18/20) showed resistance to at least four drugs simultaneously and 15% (3/20) were classified as multi drug resistant. The highest rates were found for Ciprofloxacin and Tetracycline resistance with 90% (18/20) each, followed by Nalidixic Acid with 80% (16/20), Sulfonamides 75% (15/20), Chloramphenicol and Streptomycin with 70% (14/20) each, Trimethoprim-Sulfamethoxazole 65% (13/20), Ampicillin 25% (5/20), Cefotaxime 10% (2/10) and Ceftriaxone and Gentaminicine with 5% (1/20) each.

AN ABSTRACT OF THE THESIS OF Elizabeth Schroedl, for the Master of Science degree in Chemistry, presented on June 26, 2017, at Southern Illinois University Carbondale. TITLE: DETERMINATION OF VETERINARY ANTIBIOTICS VIA POLAR ORGANIC COMPOUND INTEGRATD SAMPLING (POCIS) MAJOR PROFESSOR: Dr. Gary Kinsel A growing concern in the environment is the occurrence of antibiotics in our water systems. Antibiotics are used extensively in veterinary practices on mass production animal farms. The primary mode of transport of antibiotics into the water systems is waste-water runoff from animal lots and agricultural fields. Passive sampling systems can be deployed to monitor the amount of antibiotics entering the water systems. This paper compares the use of a commercially available passive sampling device to a home-built device using Oasis HLB sorbent disks in order to validate a less expensive method of monitoring antibiotics in water systems. The home-built device was exposed to water spiked with various concentrations of antibiotics lincomycin and oxytetracycline over a period of 10 days. Disks were extracted and sampled at days 3, 7 and 10 using LCMS detection. The mean (n=9) result for lincomycin percent recovery using HLB disks was 86% with a sampling rate of 0.02550 mL/day and 62% for oxytetracycline with a sampling rate of 0.01745 mL/day. The commercial device was exposed to various concentrations of the antibiotics for 7 days. The mean (n=3) percent recovery for lincomycin was 104% with sampling rate of 0.03204 mL/day, and 74% for oxytetracycline with a sampling rate of 0.02262 mL/day. Results between days were inconsistent; however both devices followed the same trend at each concentration. With additional investigation, the home-build device is a valid alternative to the commercially available device for monitoring antibiotics in water systems.

Abstract:

Veterinary pharmaceuticals are routinely used in livestock production to treat diseases, prevent infections, and promote growth. However, the potential release of pharmaceuticals from agricultural activities has raised concerns because they may pose detrimental effects to the ecosystems and human health, for example fostering the evolution of antibiotic-resistant bacteria in the natural environment. A better understanding of the environmental fate of veterinary pharmaceuticals is critical to properly assess and mitigate their risks. This dissertation focuses on a major group of veterinary pharmaceuticals, ionophore antibiotics (IPAs), which is sold at over 4 million kilograms per year and constitutes more than one third of the total antibiotic consumption by the livestock industry in the U.S. Despite the extensive usage of IPAs, their environmental fate was not well-understood. Therefore, this study aimed at achieving a comprehensive understanding of the occurrence, persistence, and transformation of IPAs from poultry litter before and after applications to the agricultural lands. Three of the most commonly used members of IPAs were investigated in this study: monensin (MON), salinomycin (SAL), and narasin (NAR). Based on the common management practices of poultry litter, the potential abiotic and biotic transformation reactions of IPAs were examined under varying conditions relevant to the water-soil-litter systems. This dissertation consists of three sections. First, a robust analytical method was developed to quantify IPAs in various environmental compartments, especially in high organic-containing matrices such as poultry litter, and soil and runoff from litter-fertilized lands. Efforts were made to optimize the analytical method with respect to improving extraction recovery, reducing matrix effects, and validating a surrogate standard. Second, lab-scale experiments were set up to determine the chemical properties of IPAs in aqueous environments and to study the abiotic transformation of IPAs, including hydrolysis and photolysis. The results showed that IPAs are prone to hydrolytic transformation in acidic environments, which are likely to be encountered in acidic soils, alum-amended litter (alum: Al₂(SO₄)₃•12H₂O), and acidic runoff. Multiple transformation pathways were proposed based on the identified hydrolysis products. It is also noteworthy that the hydrolysis products of MON still exhibited a toxic effect on the selected microorganism (Bacillus subtilis). SAL and NAR were found to undergo direct photolysis under both UV light and sunlight irradiation. In natural water matrix, IPAs were also degraded by indirect photolysis with hydroxyl radicals generated by light-excited nitrate. Dissolved organic matter can shield IPAs from light and slow down their photolysis. Third, the biodegradation potential of IPAs was first tested in litter and soil microcosms. Factor analysis was conducted to delineate the interaction of water and temperature on IPA degradation in the litter. Litter-fertilized and non-fertilized soil microcosms were compared on the degradation of MON and SAL. Furthermore, the inhibition and biotransformation potential of IPAs were assessed under different redox conditions with litter-enriched cultures. Inhibition tests focused on examining IPAs’ impact on microbial community functions, including denitrification, sulfate-reduction, and methane production. Biodegradation tests were conducted with different electron acceptors, including oxygen, nitrate, sulfate, and organic carbons, with efforts to elucidate primary biotransformation products. On the basis of the results obtained in this study, several recommendations on litter management and IPA selection were made to help mitigate the release and transport of IPAs, as well as enhance their degradation. Overall, this study significantly improved the understanding of the environmental fate of IPAs and the obtained knowledge can aid proper selection of IPAs and management strategies in future applications to minimize the risks of antibiotic micropollutants in the environment.

Abstract:

Pollution of aquatic ecosystems with antibiotic-resistant genes originating from human medicine and veterinary is an urgent problem due to the potential threaten to public health. Antibiotic-resistant genes enter surface waters and wastewater through vertical and horizontal water runoff. At the same time, heavy metals and biogenic substances often presented in aqueous ecosystems often exacerbate the problem since the drive the horizontal transfer of antibiotic-resistance genes. To solve the problem of purification of waters from antibiotic-resistant genes, the adsorbing agents, such as biochar, might be used. In this work, we studied the effect of biochar on the dynamics of the content of tetracycline-resistant genes in a liquid LB medium with a microbial community transferred to the medium from compost. The following additives were used - Cu (600 �g*l-1), Cd (130 �g*l-1), Ni (70 �g*l-1), Fe (1500 �g*l-1), humic acids (6%), oxytetracycline (300 mg/l). Real-time PCR revealed the absence of the tet(O) gene both in all variants with and without biochar. The highest excesses over control were found for the tet(M) and tet(C) genes. The introduction of biochar made it possible to reduce the content of antibiotic-resistant genes in all samples with different additives. Thus, in the variant with Cd, the content of the tet(A), tet(B), tet(C) � tet(S) gene was eliminated. The tet(�), tet(E) � tet(S) genes were completely absent in the sample with antibiotic.

Abstract:

Ultrasound examination is widely used in many areas of veterinary medicine, including in the diagnosis of endometritis and pregnancy in cows. However, visual diagnosis of the udder in cows has not been widely used in practice, as it does not allow to make a final diagnosis. At the same time, using ultrasound, we have the opportunity to get a clear visualization of structures, understand the severity of changes in tissues, and ultrasound is also a good method of assessing the quality of treatment in dynamics, especially for scientific purposes. In the study, patients with cow mastitis were treated with platelet autoplasm (TAP) and the healing time was compared with the use of standard antibiotic therapy.

Abstract:

Data and experiences in Sweden show that it is possible to combine high productivity in animal production with the restricted use of antibiotics. The major key factors that explain Sweden’s success in preventing AMR are: Swedish veterinary practitioners were aware of the risk of AMR as early as the 1950s, and the need for prudent use of antibiotics was already being discussed in the 1960s. Early establishment of health services and health controls to prevent, control and, when possible, eradicate endemic diseases reduced the need for antibiotics. Access to data on antibiotic sales and AMR made it possible to focus on areas of concern. State veterinary leadership provided legal structures and strategies for cooperation between stakeholders and facilitated the establishment of coordinated animal health services that are industry-led, but supported by the State.

Abstract:

Control of agro-associated pathogens is becoming increasingly difficult due to increased resistance and mounting restrictions on chemical pesticides and antibiotics. Likewise, in veterinary and human environments, there is increasing resistance of pathogens to currently available antibiotics requiring discovery of novel antibiotic compounds. These drawbacks necessitate discovery and application of microorganisms that can be used as biocontrol agents (BCAs) and the isolation of novel biologically-active compounds. This highly-synergistic one year project implemented an innovative pipeline aimed at detecting BCAs and associated biologically-active compounds, which included: (A) isolation of multidrug-resistant desert soil bacteria and root-associated bacteria from medicinal plants; (B) invitro screening of bacterial isolates against known plant, animal and human pathogens; (C) nextgeneration sequencing of isolates that displayed antagonistic activity against at least one of the model pathogens and (D) in-planta screening of promising BCAs in a model bean-Sclerotiumrolfsii system. The BCA genome data were examined for presence of: i) secondary metabolite encoding genes potentially linked to the anti-pathogenic activity of the isolates; and ii) rhizosphere competence-associated genes, associated with the capacity of microorganisms to successfully inhabit plant roots, and a prerequisite for the success of a soil amended BCA. Altogether, 56 phylogenetically-diverse isolates with bioactivity against bacterial, oomycete and fungal plant pathogens were identified. These strains were sent to Auburn University where bioassays against a panel of animal and human pathogens (including multi-drug resistant pathogenic strains such as A. baumannii 3806) were conducted. Nineteen isolates that showed substantial antagonistic activity against at least one of the screened pathogens were sequenced, assembled and subjected to bioinformatics analyses aimed at identifying secondary metabolite-encoding and rhizosphere competence-associated genes. The genome size of the bacteria ranged from 3.77 to 9.85 Mbp. All of the genomes were characterized by a plethora of secondary metabolite encoding genes including non-ribosomal peptide synthase, polyketidesynthases, lantipeptides, bacteriocins, terpenes and siderophores. While some of these genes were highly similar to documented genes, many were unique and therefore may encode for novel antagonistic compounds. Comparative genomic analysis of root-associated isolates with similar strains not isolated from root environments revealed genes encoding for several rhizospherecompetence- associated traits including urea utilization, chitin degradation, plant cell polymerdegradation, biofilm formation, mechanisms for iron, phosphorus and sulfur acquisition and antibiotic resistance. Our labs are currently writing a continuation of this feasibility study that proposes a unique pipeline for the detection of BCAs and biopesticides that can be used against phytopathogens. It will combine i) metabolomic screening of strains from our collection that contain unique secondary metabolite-encoding genes, in order to isolate novel antimicrobial compounds; ii) model plant-based experiments to assess the antagonistic capacities of selected BCAs toward selected phytopathogens; and iii) an innovative next-generation-sequencing based method to monitor the relative abundance and distribution of selected BCAs in field experiments in order to assess their persistence in natural agro-environments. We believe that this integrated approach will enable development of novel strains and compounds that can be used in large-scale operations.
