Abstract (sommario):
Resumo: A extensão universitária tem por objetivo instituir práticas cidadãs de pesquisa e ensino. Nesse contexto, o Núcleo de Estudos em Microbiologia Agrícola (NEMA), da Universidade Federal de Viçosa (UFV), tem desenvolvido atividades de extensão junto à comunidade de Viçosa e região, para o intercâmbio de experiências em pesquisa, ensino e extensão relacionadas à Microbiologia Agrícola. O presente artigo apresenta os primeiros resultados do projeto de extensão universitária desenvolvido pelo NEMA junto à Escola Família Agrícola (EFA) Puris, que adota a Pedagogia da Alternância e tem a Agroecologia como eixo norteador, visando à articulação de atividades práticas e teóricas, em tempos e espaços que se alternam entre a escola e a comunidade na qual os educandos estão inseridos. As três intervenções realizadas até o presente momento abordaram os seguintes temas: demonstração dos micro-organismos no ambiente e o papel das micorrizas; produção, comercialização e consumo de cogumelos; compostagem e produção de alimentos fermentados. No total, as atividades envolveram cerca de 65 educandos do Ensino Médio, 5 monitores da EFA e 24 acadêmicos, dentre os quais professores, técnicos, graduandos e pós-graduandos da UFV. Essas intervenções têm proporcionado um estímulo à curiosidade, antes pouco ofertada, sobre o mundo microbiano e suas aplicações, além de instigar o interesse pelo conhecimento científico e proporcionar novos desafios de ensino e extensão para os acadêmicos envolvidos. Palavras-chave: Agricultura familiar, Microbiologia agrícola, Universidade Federal de Viçosa The microbiology in the context of the agroecology: extension activity in the Puris Agricultural Family School Abstract: The university extension aims to establish citizen practices in research and teaching. In this context, the “Núcleo de Estudos em Microbiologia Agrícola (NEMA)”, from Universidade Federal de Viçosa – UFV(Viçosa, Minas Gerais State, Brazil), has developed extension activities in Viçosa and region for the exchange of experiences in research, teaching and extension related to Agricultural Microbiology. This paper presents the first results of the university extension project developed by NEMA at the Puris Agricultural Family School (EFA), which adopts the Pedagogy of Alternation for articulating practical and theoretical activities, in times and spaces concatenated between the school and the community in which students are inserted. The three interventions carried out until here were related to the demonstration of microorganisms in the environment and the role of mycorrhizae, the production, marketing and consumption of mushrooms, and the composting and production of fermented foods. In total, about 65 high school students, 5 EFA’s monitors and 24 academics and staffs from UFV were involved in the activities. These interventions have provided a stimulus to the curiosity, barely offered before, about the microbial world and their applications. Also, it has instigated the interest for the scientific knowledge and enabled new teaching and extension challenges for the academics involved.

Abstract (sommario):
Conhecimentos sobre Microbiologia promovem o cuidado pessoal, para com a saúde e o meio ambiente. Isso contribui, em uma perspectiva mais ampla, para a formação de seres mais conscientes de sua realidade. A extensão configura-se como uma das finalidades da Universidade, por meio da qual institui práticas cidadãs de pesquisa e ensino direcionadas à comunidade em geral. O presente estudo teve como objetivo analisar o perfil das ações de extensão universitária que abordam temas da Microbiologia, baseando-se na produção científica nacional das últimas duas décadas. Tais ações de extensão foram encontradas em 109 publicações deste período. Predominaram ações na área da Microbiologia Clínica (40/109), destacando-se temas como Educação e Promoção da saúde (32/109 e 22/109, respectivamente). Entre as doenças abordadas nestas ações, as Viroses (13/109) foram preponderantes frente às Parasitoses (3/109) e as Micoses (2/109). O ensino também tem sido o foco das ações de extensão em Microbiologia, uma vez que a maior parte delas desenvolveu ou aprimorou Práticas educativas (29/109), atendendo majoritariamente ao público escolar (42%). As universidades públicas participam massivamente destas ações, representando 91% das iniciativas. As informações geradas retornaram aos participantes em 74% das ações analisadas, demonstrando a importância da extensão para veicular conhecimentos científicos em diferentes públicos. Este estudo pode contribuir para que as ações voltadas à Microbiologia cresçam, se fortaleçam e aumentem ainda mais a sua significância social. Palavras-chave: Ensino de microbiologia; Educação; Saúde; Ambiente The microbiology and the university extension Abstract: Knowledge about Microbiology promotes personal and health care, in addition to the care for the environment. This knowledge contributes, in a broader perspective, to the formation of beings more aware of their reality. One of the purposes of the University, the extension is the set of research and teaching practices directed to the community in general. This study aimed to analyze the profile of university extension actions involving Microbiology themes, based on the national scientific production of the last two decades. These extension actions were found in 109 publications of this period. Actions in the ​​Clinical Microbiology area predominated (40/109), highlighting topics such as Education and Health Promotion (32/109 and 22/109, respectively). Among the diseases addressed in these actions, Viruses (13/109) were preponderant against Parasitic infections (3/109) and Mycoses (2/109). Teaching has also been the focus of extension actions in Microbiology, since most of them have developed or improved educational practices (29/109), supporting mainly the students (42%). Public universities participate massively in these actions, representing 91% of initiatives. The information generated returned to the participants in 74% of the actions analyzed, demonstrating the importance of extension to convey scientific knowledge in different audiences. This study may contribute to the actions aimed at Microbiology to grow, strengthen, and further increase their social significance. Keywords: Microbiology teaching; Education; Health; Environment

Abstract (sommario):
A reactor microbial sensor device and a membrane microbial sensor device are low-cost and convenient analytical tools, which are useful for assessment of constitutiveness and inducibility of enzyme systems for transport and initial metabolism of substrate in microbial cells. By means of these devices, it was shown for fusaric acid (5-butilpicolinic acid) and Bacillus subtilis cells that an inducible protein-transporter system without enzyme system of initial metabolism of fusaric acid exists in cells of Bacillus subtilis.

Abstract (sommario):
Infected aneurysms of the aorta were first described as a result of septic emboli or contiguous spread from bacterial endocarditis and are usually caused by Staphylococcus or Salmonella species. We report a case of Nocardia-associated infected aneurysm of the native suprarenal aorta in an immunocompromised host. Surgical management consisted of placement of an interposition cryopreserved aortic homograft. Nocardia asteroides was identified on a microbiology specimen of the aorta and both microbiology and pathology specimens of the splenic tissue. To the best of our knowledge, this represents the first carefully documented, unique case of a Nocardia-infected aneurysm treated with homograft interposition. In addition, pathologic and microbiologic data are included from the postmortem examination 10 months later.

Abstract The proficiency testing program in food microbiology (Réseau d' Analyses et d'Echanges en Microbiologie des Aliments; RAEMA), created in 1988, currently includes 440 participating laboratories. The program establishes proficiency in detection of Salmonella and Listeria monocytogenes, as well as quantitation of aerobic microorganisms, Enterobacteriaceae, coliforms, Escherichia coli, Clostridium perfringens, coagulase-positive Staphylococcus, and Listeria monocytogenes. Twice a year, 5 test samples are sent to participants to assess their precision and trueness for enumeration and detection of microorganisms. Results show an increasing involvement of food microbiology laboratories in quality assurance programs and use of standard and validated analytical methods. However, the percentage of laboratories obtaining questionable and unsatisfactory microbiological results remains relatively onstant.

Abstract (sommario):
Context.— Specimen quality is paramount for microbiology culture in order to ensure the testing is performed appropriately and the results, generated accurately, reflect the patient's clinical situation and guide proper treatment. Several factors play a critical role in guaranteeing the accuracy of the culture results, including adequate specimen collection by the surgeon, proper labeling, and timely transport to the laboratory. Objective.— To educate pathologists, surgeons, and other medical personnel involved in the collection and processing of surgical specimens submitted for microbiologic culture. To assure the pathogen is correctly identified, proper protocols must be followed. The accurate identification of the infectious microorganisms from surgical specimens is vital for the treating clinician to ensure the correct antimicrobial therapy is administered. Data Sources.— An analysis of relevant literature was performed by using PubMed. Articles were selected on the basis of their relevance to the topic as well as their date of publication. Articles published between 2000 and 2018 were deemed sufficient for inclusion, while older references, regardless of relevance, were excluded. Conclusions.— The process of properly obtaining specimens for microbiology culture from the operating room is a complex process that requires collaboration between the collecting surgeon and the pathologist and microbiology laboratory in order to provide the highest quality of results from which important treatment decisions are then implemented. Engaging leadership to develop mutually agreed-upon institutional best practices will help not only to standardize practices but also to improve the quality of microbiology results reported.

Abstract (sommario):
BACKGROUND: Microbiologic screening of extrapulmonary TB (EPTB) patients could inform recommendations for aerosol precautions and close contact prophylaxis. However, this is currently not routinely recommended in India. Therefore, we estimated the proportion of Indian patients with EPTB with microbiologic evidence of pulmonary TB (PTB).METHODS: We characterized baseline clinical, radiological and sputum microbiologic data of 885 adult and pediatric TB patients in Chennai and Pune, India, between March 2014 and November 2018.RESULTS: Of 277 patients with EPTB, enhanced screening led to the identification of 124 (45%) with concomitant PTB, including 53 (19%) who reported a cough >2 weeks; 158 (63%) had an abnormal CXR and 51 (19%) had a positive sputum for TB. Of 70 participants with a normal CXR and without any cough, 14 (20%) had a positive sputum for TB. Overall, the incremental yield of enhanced screening of patients with EPTB to identify concomitant PTB disease was 14% (95% CI 12–16).CONCLUSIONS: A high proportion of patients classified as EPTB in India have concomitant PTB. Our results support the need for improved symptom and CXR screening, and recommends routine sputum TB microbiology screening of all Indian patients with EPTB.

Abstract Objectives Printculture is a method of microbiologic assessment previously described for use in the autopsy setting. We sought to compare printculture of surgical and autopsy pathology specimens to standard microbiology culture using matrix-assisted laser desorption/ionization–time of flight (MALDI-TOF)–based colony identification. Methods Printculture was performed on 18 frozen samples with corresponding standard culture results. The results of MALDI-TOF identification of colonies recovered by printculture were compared with standard cultures, and percent concordance was calculated. Results There was 95.8% concordance to standard culture methods for cases with infections and 100% concordance for cases without infection. The pattern of growth was found to aid in the distinction between contamination and true infection. Conclusions Printculture allows the identification of microorganisms from routinely frozen tissues and provides a bridge between microbiology and histomorphology through the identification of associated histologic features of infection. This technique can be successfully integrated into autopsy and surgical pathology workup of potentially infected tissues.

Abstract (sommario):
Objectives The study’s aim is to assess if vulvar psoriasis and candidiasis may be distinguished by clinical presentation and histopathologic appearance. Methods The pathology database identified biopsies with corneal or subcorneal neutrophils, acanthosis, and dermal lymphocytic infiltrate. Exclusions were age younger than 18 years and unavailable or uninterpretable slides. Clinical data included demographics, comorbid conditions, symptoms, examination, microbiology, treatment, and response. Histopathologic review documented site, thickness, and characteristics of stratum corneum and epidermis, distribution of neutrophils, and infiltrate. Cases were stratified by microbiologic presence or absence of Candida albicans. Results Biopsies from 62 women with median age of 60 years were associated with C. albicans on vulvovaginal culture in 28 (45%), whereas 26 (42%) were negative, and 8 (13%) lacked microbiologic assessment. Swab-positive women were more likely to have diabetes, receive prereferral estrogen, and report vulvar pain. Specialist clinical impression was candidiasis in 33 (53%), psoriasis in 11 (18%), comorbid candidiasis and psoriasis in 7 (11%), dermatitis in 10 (16%), and unknown in 2 (3%). Visible fungal organisms occurred in 16 (26%) cases and were associated with diabetes and satellite lesions. Other than presence of organisms, there were no histopathologic differences stratified by microbiologic result. Conclusions The histopathologic triad of corneal/subcorneal neutrophils, acanthosis, and dermal lymphocytic infiltrate is common to vulvar psoriasis and candidiasis, and clinical features do not reliably distinguish between them. Microbiologic assessment and single-agent treatment are useful strategies to clarify the diagnosis.

Abstract (sommario):
Atypical mycobacteria that cause disseminated disease result in significant morbidity and mortality among patients with advanced human immunodeficiency viral infection. Although significant progress has been made with respect to our understanding of the epidemiology, microbiology, and pathogenesis of Mycobacterium avium complex (MAC) infections in patients with the acquired immunodeficiency syndrome (AIDS), treatment and prevention strategies are still emerging. A series of case‐controlled studies and clinical trials evaluated various combinations of traditional and investigational antimycobacterial agents, and demonstrated modest clinical and microbiologic success in the treatment of disseminated MAC infection. Prevention studies proved rifabutin and clarithromycin to be rational prophylaxis agents. Continued identification of optimum combination regimens remains essential to curtail the increasing frequency of disseminated MAC disease in patients with AIDS.

Abstract (sommario):
Abstract Background Urine cultures to confirm a urinary tract infection (UTI) are not consistently collected in the primary care setting; thus estimates of the prevalence of resistance in uropathogens may be biased. As part of an ongoing study, microbiologic cultures were collected for all patients presenting with uncomplicated UTI at primary care clinics over a six-month period to assess the potential misclassification in frequency of resistance. Methods Data from an electronic health record repository were used to identify clinic encounters for women with a diagnosis code for unspecified UTI or cystitis from six primary care clinics between October 1, 2015 and February 28, 2017 in this cross-sectional study. Prior to August 22, 2016, urine microbiology cultures were collected at the discretion of the provider (usual care period), and from August 22, 2016 to February 28, 2017 urinary microbiology cultures were collected from all patients suspected of having uncomplicated UTI (full culturing period). Urinary microbiology culture and pharmacy data occurring within three days of the encounter were collected. Antibiotic susceptibility data was summarized for isolated Enterobacteriaceae. Frequency of susceptibility to trimethoprim-sulfamethoxazole (TMP-SMX), nitrofurantoin, and fluoroquinolones were compared between usual care vs. the full culturing periods using a chi-square test. Results We identified 131 urine microbiology cultures in the usual care period and 104 in the full culturing period with 61.1% and 55.8%, respectively, being positive cultures. Enterobacteriaceae were isolated from 85.0% of positive cultures in the usual care period and 86.2% in the full culturing period. Between the usual and full culturing periods, antibiotic susceptibility in the Enterobacteriaceae did not differ statistically for TMP-SMX (85.1% vs.. 88.0%; P = 0.65), nitrofurantoin (98.5% vs. 94.0%; P = 0.19), and fluoroquinolones (89.6% vs. 90.0%; P = 0.94). Conclusion Full culturing did not significantly change estimates of the prevalence of antibiotic resistance among Enterobacteriaceae isolated from urine samples. Current urine culturing practices provide adequate susceptibility information to inform empiric prescribing for women with uncomplicated UTIs. Disclosures J. C.

Abstract (sommario):
Context Use of reference laboratories for selected laboratory testing (send-out tests) represents a significant source of laboratory costs. As the use of more complex molecular analyses becomes common in the United States, strategies to reduce costs in the clinical laboratory must evolve in order to provide high-value, cost-effective medicine. Objective To report a strategy that employs clinical pathology house staff and key hospital clinicians in the effective use of microbiologic send-out testing. Design The George Washington University Hospital is a 370-bed academic hospital in Washington, DC. In 2012 all requisitions for microbiologic send-out tests were screened by the clinical pathology house staff prior to final dispensation. Tests with questionable utility were brought to the attention of ordering clinicians through the use of interdisciplinary rounds and direct face-to-face consultation. Results Screening resulted in a cancellation rate of 38% of send-out tests, with proportional cost savings. Nucleic acid tests represented most of the tests screened and the largest percentage of cost saved through screening. Following consultation, requested send-out tests were most often canceled because of a lack of clinical indication. Conclusions Direct face-to-face consultation with ordering physicians is an effective, interdisciplinary approach to managing the use of send-out testing in the microbiology laboratory.

Abstract (sommario):
The use of culture-independent methods has deepened our appreciation of the complexity of the bacterial communities that typically reside in the airways of persons with cystic fibrosis (CF). New insights into how changes in the structure of these communities relate to lung disease progression will likely raise expectations for more in-depth microbiologic analysis of CF respiratory specimens. An article in this issue of theJournal of Clinical Microbiology(W. G. Flight, A. Smith, C. Paisey, J. R. Marchesi, M. J. Bull, P. J. Norville, K. J. Mutton, A. K. Webb, R. J. Bright-Thomas, A. M. Jones, and E. Mahenthiralingam, J Clin Microbiol 53:2022–2029, 2015,http://dx.doi.org/10.1128/JCM.00432-15) describes the application of a culture-independent approach to the assessment of CF airway microbiota.

Abstract (sommario):
Abstract Objectives Testing of bronchoalveolar lavage specimens with acid-fast bacilli (AFB) stain is not routinely performed in many institutions. In 2017, we began performing AFB stain on all BAL specimens submitted for cytologic examination. Herein, we evaluate the diagnostic value of this test in comparison to the auramine rhodamine fluorescent stain performed in parallel by the microbiology laboratory for specimens also submitted for AFB culture. Methods We retrospectively reviewed all BAL specimens that were reported as culture positive for Mycobacteria spp. (n = 109) by our microbiology laboratory between 7/20/2017 and 12/30/2018. Of these, 84 (77.0%) specimens were concurrently submitted for cytologic examination and reviewed by a board-certified cytopathologist. Results Of the 84 culture-positive BAL specimens submitted for cytologic exam, only 2 cases were positive for acid-fast bacilli on cytologic examination with AFB stain, yielding a sensitivity of 2.38%. In comparison, 11 of those specimens were identified on auramine rhodamine fluorescent stain, yielding a sensitivity of 13.1%. Both cases identified by the AFB stain on cytology were also identified by auramine rhodamine stain in microbiology. These data indicate that AFB stain conducted in cytology is 81.2% less sensitive for detection of AFB when compared to auramine rhodamine stain. All cases identified on smear and AFB stain (n = 11) belonged to the Mycobacterium avium-intracellulare complex. Conclusion Our study results suggest that in a low-prevalence population, the use of AFB stain on BAL specimens sent for cytologic examination lacks sensitivity and is unnecessary if the same specimen is also sent for microbiologic culture and auramine rhodamine stain. The use of AFB stain on BAL specimens that were not sent for AFB culture is suboptimal but may identify AFB in specimens obtained from patients for whom mycobacterial infection is not in the differential and may be clinically insignificant.

Abstract (sommario):
Background The relationship between microbiology and histology in patients with ventilator-associated pneumonia has been sparsely described. Methods Twenty-five patients who died in the intensive care unit after their lungs had been mechanically ventilated for 72 h were studied. Twenty of the 25 died with clinical suspicion of pulmonary infection. A total of 375 immediate postmortem pulmonary biopsies were obtained after death and processed for quantitative microbiology and histology. Four evolutionary stages of pneumonia were defined: early, intermediate, advanced, and resolution. Results At least one specimen with histologic evidence of pneumonia was found in all but two patients (92%). Histologic pneumonia was a widespread and frequent process (46%) of biopsies examined) involving predominantly the lower lobes (55% of all biopsies with pneumonia) and showing different histopathologic stages of progression coexisting in the same lung lobes. Lung cultures were frequently polymicrobial (149 of 375, 40% of the pulmonary biopsy cultures, and 20 of 25, 80% of the cases) and not always yielding the same pathogen (19 microorganisms) when comparing one lung to the other. Histopathology and microbiologic biopsy cultures showed a weak relationship (28% and 49% of species had counts > or = 10(3) cfu/g in samples without pneumonia from patients with and without prior antibiotic treatment, respectively). Histopathologic evolutionary stages were not associated with any differences in quantitative culture results of pulmonary biopsies, independently of prior administration of antibiotics. Higher bacterial concentrations of biopsy cultures were associated with the absence of prior antibiotic treatment. Conclusions Ventilator-associated pneumonia is a frequent diffuse and polymicrobial process showing different coexisting degrees of evolution and involving preferentially the lower lobes. Microbiology and histology can be dissociated even in the absence of prior antibiotic treatment. Lung histology appears more reliable than bacteriology as a diagnostic reference test.
