Introducción: Las infecciones del tracto urinario (ITU), constituyen una de las infecciones bacterianas más prevalentes, sus agentes etiológicos incluyen Escherichia coli, Klebsiella spp, Proteus spp, Enterococcus spp, Pseudomonas spp y Staphylococcus spp, los cuales presentan prevalencias y perfiles de susceptibilidad antibiótica diferentes entre poblaciones. Objetivo: Determinar la prevalencia de ITU, uropatógenos y el perfil de susceptibilidad antimicrobiana en una Institución Prestadora de Servicios de Salud (IPS) de Medellín, 2011-2012. Métodos: Estudio de prevalencia en 1.959 individuos atendidos en una IPS de tercer nivel. Se calcularon medidas de resumen, proporciones, razones de prevalencia, Chi cuadrado y Fisher. Se cuantificó la modificación del efecto (confusión o interacción) con análisis estratificado y modelos de regresión logística binaria en SPSS 21.0®. Resultados: La prevalencia de ITU fue 31% los principales agentes etiológicos fueron E. coli (69%), Enterococcus spp (11%) y Klebsiella spp (8%). La ITU y la infección por E. coli fueron estadísticamente mayores en mujeres y adultos mayores. La mayor frecuencia de resistencia de E. coli fue para ampicilina (61%), Ácido nalidixico (48%), TrimetropinSulfa (48%) y Ciprofloxacina (42%); mientras que en Klebsiella spp fue Ampicilina (100%), TrimetropinSulfa (23%), Ampicilina- Sulbactam (22%) y Cefalotina (19%). Conclusión: La elevada prevalencia de ITU, la multiplicidad de uropatógenos aislados, la identificación de grupos de mayor riesgo y la diversidad de perfiles de resistencia antibiótica, evidencian la necesidad de desarrollar investigaciones locales que permitan orientar las acciones en salud y vigilancia epidemiológica, acordes con las particularidades de cada población.

As infecções bacterianas do trato urinário (ITUs) são causa comum de doença em cães, gatos e humanos. Embora bactérias Gram positivas como Staphylococcus spp., Streptococcus spp. e Enterococcus spp., possam ocasionar ITUs, as bactérias Gram negativas (Escherichia coli, Proteus spp., Klebsiella spp., Pseudomonas spp. e Enterobacter spp.) respondem por 75% dos casos. Este estudo teve como objetivo determinar a frequência de diferentes gêneros de bactérias em ITUs em cães e gatos, bem como a sua sensibilidade aos antimicrobianos utilizados na rotina clínica. Portanto, amostras de urina de 100 cães e gatos com sinais de ITU foram coletadas assepticamente, sofrendo avaliação microbiológica por meio de métodos qualitativos e quantitativos, além de urinálise. Todos os isolados foram submetidos a testes de sensibilidade aos antimicrobianos. ITU foi confirmada em 74% dos animais, não havendo predominância quanto ao sexo. No que diz respeito à idade, 85% dos cães e 87% dos gatos tinham idades superiores a seis anos. Noventa e cinco cepas bacterianas foram isoladas, com maior frequência de Escherichia coli (55% do total) dos sorogrupos O6 e O2. Constatou-se níveis elevados de resistência a antimicrobianos nas cepas isoladas. Para as cepas Gram positivas, tetraciclina (46,1%), enrofloxacina, cotrimazol e estreptomicina (42,3% cada) foram as drogas com os maiores índices de resistência. Para as Gram negativas, amoxacilina e tetraciclina apresentaram percentuais acima de 50%. Multiresistência foi verificada em mais de 50% dos principais gêneros isolados. Considerando-se que as cepas de E. coli apresentam potencial zoonótico e forte participação na disseminação de resistência aos antimicrobianos, ressalta-se a importância do papel do médico veterinário na prevenção e controle das ITUs animais e sua contribuição para a saúde pública.

Zusammenfassung Gegenstand: Retrospektive Untersuchung der mittels bronchoalveolärer Lavage (BAL) gewonnenen Keimflora der tiefen Atemwege erkrankter Hunde auf ihre Antibiotikaempfindlichkeit über 5 Jahre. Material und Methoden: Auswertung der Ergebnisse der Agardiffusionstests von Bakterienisolaten, die in den Jahren 2004–2009 von 84 Hunden isoliert wurden, und Vergleich mit den Resultaten einer gleichartigen Analyse der Jahre 1999/2000. Ergebnisse: Bei den 99 geprüften Bakterienisolaten handelte es sich um Pasteurella spp. (27,3%), Bordetella bronchiseptica (20,2%), Staphylococcus spp. (18,2%), Escherichia coli (15,2%), Klebsiella spp. (8,1%), Pseudomonas spp. (7,0%) und Streptococcus spp. (4,0%). Bei acht Hunden lagen Mischkulturen vor. Die Mehrzahl der Bordetella-(B.-)bronchiseptica-Isolate erwies sich als sensibel gegenüber den Fluorchinolonen sowie Tetracyclin, Doxycyclin und Polymyxin B. Im Vergleich zu 1999/2000 zeigte sich ein höherer Anteil der gegenüber Amoxicillin/Clavulansäure und Chloramphenicol empfindlichen B.-bronchiseptica-Isolate, wobei die Zunahme bezüglich Chloramphenicol statistisch signifikant war. Die überwiegende Anzahl der Staphylococcus-Isolate erwies sich gegenüber Enrofloxacin, Marbofloxacin, Amoxicillin/Clavulansäure, Chloramphenicol, Cephalexin, Doxycyclin und Polymyxin B sensibel. Im Vergleich zu 1999/2000 ergab sich ein erhöhter Anteil an Chloramphenicolund Tetracyclin-sensiblen Staphylococcus-Isolaten. Der Anteil Enrofloxacin-sensibler KlebsiellenIsolate betrug 62,5%, während er 1999/2000 bei 100% lag. Eine Sensibilität aller getesteten Klebsiellen-Isolate ließ sich noch gegenüber Polymyxin B nachweisen. Kein Antibiotikum zeigte eine Wirksamkeit gegenüber allen E.-coli-Isolaten. Statistisch signifikant war die Abnahme der gegenüber Amoxicillin/Clavulansäure-sensiblen Isolate. Schlussfolgerung und klinische Relevanz: Die Studie unterstreicht den Nutzen der BAL für eine ätiologische Diagnostik und den anschließenden fundierten Einsatz von Antibiotika. Die Mehrzahl der Bakterienisolate erwies sich als empfindlich gegenüber den Fluorchinolonen.

Urinary tract infection (UTI) is the infection that occurs in the urinary tract by the invasion of pathogenic bacteria, fungi, virus etc. under some circumstances only. Some common pathogenic bacteria associated with UTI include Escherichia coli, Proteus spp., Streptococcus spp., Staphylococcus spp., Pseudomonas spp. In the ongoing research work, about 30 UTI patients were selected randomly to detect the pathogen responsible for causing urinary tract infection and also to demonstrate their drug resistant traits. Among the 30 samples, about 14 samples were found to harbor Proteus spp. (1×104 cfu/ml to 1×105 cfu/ml). Escherichia coli was found to be the second predominant agent for UTI and recovered from 13 samples. Among the rest 3 samples, Pseudomonas spp. was found in 2 samples and Klebsiella spp. was found in one sample. Identified isolates showed resistance against different ranges of antibiotics. The study findings revealed the fact that emerging drug resistance of different pathogenic bacteria could become the major difficulties in the treatment of infectious diseases like UTI.Stamford Journal of Microbiology, Vol.6(1) 2016: 34-38

Zusammenfassung Gegenstand und Ziel Bakterielle Hautinfektionen kommen bei Reptilien häufig vor. Obwohl viele dieser Infektionen durch multifaktorielle Probleme verursacht werden, ist eine spezifische Behandlung nötig. Ziel der Studie war, das Keimspektrum und die Resistenzlage von aeroben Bakterien in Hautläsionen von Reptilien zu untersuchen. Material und Methoden Tupferproben dermaler Läsionen von 219 Reptilien wurden bakteriologisch untersucht (01/2017–06/2018). Die Identifizierung der Bakterien erfolgte anhand von Selektivnährböden, biochemischen Parametern sowie MALDI-TOF-MS, die Erstellung der Antibiogramme mittels Mikrodilutionsmethode. Ergebnisse Bei den insgesamt identifizierten 306 Keimisolaten handelte es sich überwiegend um gramnegative Spezies. Pseudomonas spp. (n = 48), Citrobacter spp. (n = 31, nur bei Schildkröten), aerobe Sporenbildner (n = 30), Aeromonas spp. (n = 20), Acinetobacter spp. (n = 20), Proteus spp. (n = 15), Staphylococcus spp. (n = 15), Klebsiella spp. (n = 13), Enterococcus spp. (n = 13) sowie Morganella spp. (n = 11) machten den Hauptteil aus, daneben konnten weitere gramnegative (n = 78) und grampositive (n = 12) Bakterienspezies identifiziert werden. Mischkulturen mit 2 (n = 80) oder mehr (n = 16) Keimen traten bei 96 Tieren auf. Von 208 der 306 Isolate wurden Antibiogramme erstellt. Gegenüber Enro- (E) und Marbofloxacin (M) waren viele Isolate sensibel (minimale Hemmkonzentration [MHK] in µg/ml ≤ Grenzwert), beispielsweise Pseudomonas spp. (E: 86,4 % MHK ≤ 0,5; M: 95,5 % MHK ≤ 1), Citrobacter spp. (E: 86,4 % MHK ≤ 0,5; M: 90,9 % MHK ≤ 1) und Aeromonas spp. (E: 75,0 % MHK ≤ 0,5; M: 100 % MHK ≤ 1). Trimethoprim/Sulfamethoxazol erwies sich als wirksam gegen die meisten Citrobacter- (90,9 % MHK ≤ 2/38) und Aeromonas- (75,0 % MHK ≤ 2/38) Isolate. Amikacin war wirksam gegen fast alle Pseudomonas spp. (97,7 % MHK ≤ 16), Citrobacter spp. (95,5 % MHK ≤ 16) sowie Aeromonas spp. (93,8 % MHK ≤ 16). Schlussfolgerung und klinische Relevanz Das Keimspektrum von Reptilienhautläsionen umfasst vor allem gramnegative Bakterien, deren klinische Relevanz für jeden Einzelfall abzuwägen ist. Viele Isolate dieser Studie waren sensibel für Fluorchinolone sowie Aminoglykoside. Da der Einsatz dieser Antibiotika zurückhaltend erfolgen sollte und gegenüber jeder getesteten Antibiotikagruppe auch resistente Isolate identifiziert wurden, wird eine Antibiogrammerstellung empfohlen.

As infecções do trato urinário (ITUs) ocorrem devido à invasão, multiplicação e colonização do trato urinário por bactérias e fungos. As ITUs são mais frequentes em crianças menores de 1 ano, em adultos do sexo feminino e idosos. O desenvolvimento de ITU está relacionado com estado imunológico, idade, uso abusivo de antimicrobianos e anormalidades morfofuncionais do trato urinário. Os microrganismos mais frequentemente envolvidos incluem bactérias da família Enterobacteriaceae. A urocultura é o melhor procedimento laboratorial para diagnóstico das ITUs. As situações mais incidentes quanto a não adequação das amostras para realização do exame estão associadas à coleta, transporte e armazenamento. O artigo teve como objetivo conhecer o índice de solicitações de nova coleta para urocultura em um laboratório clínico e avaliar os motivos dessas solicitações sugerindo medidas alternativas que minimizem seus inconvenientes. Foram obtidos dados existentes nos arquivos de solicitação de nova amostra do Laboratório Escola de Análises Clínicas da Universidade Tiradentes (UnitLab), situado em Aracaju/SE. No período de fevereiro de 2010 a dezembro de 2012, foram solicitadas 111 novas coletas para urocultura no UnitLab, sendo 31, em 2010, 38, em 2011 e 42, em 2012. Os motivos de solicitação de nova coleta foram amostra desprezada (3%), armazenamento inadequado (6%), confirmação de resultado (27%), contaminação (59%) e não definido (5%). O resultado das novas coletas solicitadas para urocultura foi amostra negativa (51%), pendente (32%), amostra positiva (14%) e contaminada (3%). Dentre as novas coletas positivas os agentes etiológicos identificados foram Escherichia coli (69%), Pseudomonas spp. (6%), Klebsiella spp. (6%) e Enterobacter cloacae (6%). Houve identificação de infecção mista, com Pseudomonas spp. e Staphylococcus spp. / Micrococcus spp. (13%). Para minimizar os inconvenientes sugere-se que haja uma maior comunicação entre o clínico e o paciente, na qual informações sobre os procedimentos de coleta, transporte e armazenamento sejam passadas, e que os laboratórios busquem melhorar a qualidade dos serviços prestados.

Para a investigação das causas de aborto eqüino na região de Curitiba, realizou-se a coleta e processamento do material de casos de aborto para bacteriologia, virologia e histologia; e um levantamento estatístico geral dos casos de aborto. Durante três anos, foram acompanhadas 674 gestações, das quais 9,2% resultaram em aborto. Com relação a abortos gemelares, verificou-se um índice de 4,5% em um total de 132 casos analisados. O material de 21 fetos foi processado com o intuito de isolar-se o Herpesvírus eqüino tipo 1, obtendo-se o isolamento em 4 casos (19,0%). Foram examinados para bacteriologia um total de 38 fetos, dos quais 44,7% foram considerados bacteriologicamente positivos. As bactérias isoladas com maior freqüência foram: Streptococcus spp., Klebsiella spp., Escherichia coli, Pseudomonas spp. e Staphylococcus spp.. Foram descritas as alterações encontradas no exame histológico da maioria dos casos de aborto de origem bacteriana e viral. Abstract This research was undertaken with the aim of establishing the main causes of equine abortion in the Curitiba area. It has been established that during the period of three years occurred a total of 9.2 per cent abortions among 674 gestations studied. From 50 aborted fetuses, different biological material was collected for bacteriology, virus and histopathology analysis. A total of 4.5 per cent of twin abortions were observed among 132 cases of abortions studied. The equine Herpesvirus type 1 has been successfully isolated from 4 cases, among 21 fetuses studied. On the other hand, 44.7 per cent from 38 fetuses studied were considered positive for bacteriological testing. The most frequent bacteria recovered were Streptococcus spp., Klebsiella spp., Escherichia coli, Pseudomonas spp. and Staphylococcus spp. The alterations found in the histological examination of the majority of bacteriological and virological abortion cases were desccribed.

The sanitary evaluation of equipment and hands is fundamental to investigate the presence of pathogens in the dairy industry. Then, this study aims to evaluate the sanitization of equipment, workers’ hands, raw and pasteurized milk in goat milk dairies in the Cariri region, state of Paraíba.  Collected 32 samples of four dairies represented by letters A, B, C, and D. The followings contents were analyzed: mesophiles, total and thermotolerant coliforms, Escherichia coli, Staphylococcus aureus, Samonella spp. and Listeria monocytogenes in the reception tank, pasteurization tank, packing machine, package, wall, workers’ hand, and each dairy’s raw and pasteurized milk. After isolation, 84 colonies were confirmed by MALDI TOF. The indicator microorganisms presented variations for the workers’ hands, while A and B stayed within the patterns. For the equipment, only dairy B was within limits. They were out of the standard for mesophiles, total coliforms, and thermotolerant regarding raw and pasteurized milk. The microorganisms, the Enterobacteriaceae family presented a higher frequency, with 77.38%, and within this family, Escherichia coli, Klebsiella spp., and Enterobacter spp. were the most prevalent. Gram-positive corresponded to 22.62%, Bacillus spp., Staphylococcus spp., Enterococcus spp., and Macrococcus caseolyticus. Listeria monocytogenes and Salmonella spp. were not isolated. These demonstrate failures in goat milk processing with pathogenic bacteria in several dairy plants, indicating the need to adjust the product’s quality control.

INTRODUCTION: The study under view is based under the aim to investigate the prevalence and susceptibility pattern of pathogens, causing urinary tract infections (UTIs), to antibiotics commonly used in routine medication. MATERIALS AND METHODS: Over a period of 10 months 100 isolates were collected for the determination of their susceptibility to chosen antibiotics, from a laboratory (MedPath Laboratories) in urban area of Karachi. All Gramnegative and Gram-positive urinary tract pathogens were re-identified by their morphological and biochemical characteristics and the susceptibility to seven antibiotics was determined. RESULTS: Pathogens were found as, Escherichia coli, Pseudomona spp, Klebsiella species, Enterobacter spp., and Staphylococci spp. In recent study, more than half of the Escherichia coli isolates were resistant to one or more of the all antimicrobial drugs tested. Resistance was most common to amoxicillin/clavulanic acid and ofloxacin, cefixime, followed by gentamicin. Our results indicate that Escherichia coli and Pseudomonas spp. were the most common organisms causing UTI. Other organisms involved were Enterobacter spp., Staphylococcus spp., and Klebsiella spp. Increasing patterns of resistant to gentamicin, and ofloxacin were also observed. CONCLUSIONS: In conclusion, pattern of antibiotic susceptibility to first line antibiotics is changing hence antimicrobial susceptibility testing of all isolates is crucial for the treatment of UTI.

Nine hundred and fifty two milk samples from clinical bovine mastitis cases, originated from 269 farms in Northern Greece, were tested. Escherichia coli was isolated in 49.3% of samples. Furthermore, Staphylococcus spp, Corynebacterium spp, Streptococcus spp, Pseudomonas spp, Proteus spp, Klebsiella spp or a combination of the above bacteria were isolated. The bacteriological result from 4.3% of samples was negative. No correlation between clinical mastitis cases and seasonal variation was observed. Resistance of E. coli isolates to tetracycline was 82-96%, to enrofloxacin 10-30%, to gentamicin 58-80%, to cephalosporins 47-75%, to sulfamethoxazole-trimethoprime 46-81%, to ampicillin 71-92% and to neomycin 83-97%. The highest resistance rate and the appearance of multi-resistant isolates of E. coli (6%), to 8 antibacterials, were recorded during the last year of the survey.
