Background: The presence of resistant and potentially virulent bacterial strains in a veterinary hospital environment is a neglected problem.  Pseudomonas aeruginosa is an opportunistic microorganism present and circulating in the veterinary hospital environment, of clinical importance and zooanthroponotic transmission of P. aeruginosa has also been reported. The aim of this study was to characterize the population of P. aeruginosa present in a veterinary hospital environment by evaluating their resistance profile and biofilm production.Materials, Methods & Results: A total of 306 samples were collected from the veterinary hospital environment (swabs from consultation tables, surgical tables, door handles, hospitalization cages, stethoscopes, thermometers, and muzzles). The isolates were biochemically identified as belonging to the species Pseudomonas aeruginosa through nitrate to nitrite reduction, motility and oxidase test, growth at 42°C, pigment production, and alkalinization of acetamide. Antimicrobial resistance was tested using the minimum inhibitory concentration (MIC) test. Twenty seven isolates of P. aeruginosa were obtained, with a frequency of 8.8%. The detection of beta-lactamase production and biofilm formation genes by polymerase chain reaction (PCR). Two multidrug resistant (MDR) and 3 single-drug resistant (SDR) strains of P. aeruginosa were identified. Furthermore, it was observed that the strains carried genes related to beta-lactamase production (TEM and CTX-M group 25) and biofilm production (pelA, pslA, ppyR).Discussion: Pseudomonas aeruginosa is considered a major cause of opportunistic hospital infections, as it causes significant morbidity and mortality in immunosuppressed individuals, both in animals and in humans. Veterinary hospitals can harbor microorganisms that cause infections, as well as multiresistant agents. Normally, these environments have a large circulation of people and animals, which particularly enables a facilitated dissemination of these resistant microorganisms. Recently, the World Health Organization (WHO) listed carbapenem-resistant P. aeruginosa as one of 3 bacterial species in critical need for the development of new antibiotics to treat their infections. The data found in this work strengthen the knowledge on the antimicrobial resistance capacity that P. aeruginosa exhibits. The presence of 3 multiresistant strains further highlights the advanced stage of resistance of this bacterial species. The characterization of strains of this species in a veterinary hospital environment is crucial for the control of this population circulating in this environment, and the consequent adoption of more effective measures aimed at controlling its proliferation. The study of this bacterial species in a veterinary hospital environment has a direct impact on human health, due to the mechanisms of resistance and genetic variability that can occur between infections in different animal species and in humans. In view of that, professionals working in veterinary hospitals should be aware of the importance of controlling these microorganisms. Correct measures must be taken to sanitize the environment and utensils between animal care sessions, besides frequent hand washing by all employees and the use of protective equipment such as masks and gloves. The presence of potentially biofilm-producing MDR and SDR strains indicates the free circulation of these bacteria in the veterinary hospital environment. Thus, as a potentially pathogenic microorganism to humans and animals, containment measures must be taken to prevent this possible transmission.Keywords: bacteria, antimicrobial resistance, multidrug resistant, beta-lactamase, biofilm, veterinary care.

O uso de testes rápidos na rotina clínica veterinária The use of quick tests in the veterinary clinical routine

A salmonelose aviária é um termo usado para se referir aos três tipos diferentes de doenças bacterianas causadas pelo gênero Salmonella sp (pulorose, tifo aviário e paratifo aviário) nas aves domésticas. A pulorose tem sua etiologia relacionada à Salmonella pullorum, o tifo aviário à Salmonella gallinarum e o paratifo aviário a todos os demais sorotipos patogênicos entéricos. As três doenças podem acometer aves domésticas de qualquer idade causando sinais clínicos inespecíficos e sistêmicos, com quadros agudos e crônicos que podem ser confundidos com outras bacterioses. Mundialmente disseminadas, essas doenças são responsáveis por causar impactos na economia brasileira e na saúde pública. A transmissão pode ocorrer pela via vertical e horizontal e pelo contato indireto com alimentos, água de beber, vetores e fômites contaminados. O diagnóstico das aves doentes pode ser realizado com base no histórico, sinais clínicos, achados anatomopatólogicos e exames laboratoriais que incluem a identificação dos agentes por meio de isolamento bacteriano, soroaglutinação rápida em placas, soroaglutinação lenta em tubos e reação em cadeia da polimerase (PCR). Como não há tratamento antibiótico que elimine completamente a infecção nas aves as medidas de controle e prevenção são indispensáveis no controle. O presente artigo trata-se de uma revisão de literatura e tem como objetivo conhecer o referencial teórico referente à doença e aos seus agentes, além da possibilidade de esclarecer a importância da prevenção e do controle desse microrganismo, devido ao caráter  infectocontagioso e zoonótico da doença, que pode causar inúmeros prejuízos econômicos e impactos negativos para a saúde pública.

The parasitic skin diseases, specifically mange diseases, are highly relevant in the animal health studies, due to a significant number of cases in the veterinary routine, beyond the importance in public health, due to zoonotic potential. Therefore, this study aimed report the occurrence of mange skin diseases with notes in the zoonotic potential from Jataí, Goiás, by an retrospective survey of mange cases diagnosed in dogs and cats treated at the Veterinary Hospital of the Federal University of Jataí. A total of 612 reports of parasitological tests, comprising cerumen swabs and skin scraping, were analyzed from January 2016 to December 2019. The most common causative mite in dogs was Demodex canis (10.94%), followed by Otodectes cynotis (2.92%), and Sarcoptes scabiei (2.54%). The most common causative mite in cats was Notoedres cati (20%), followed by O. cynotis (10%). These skin diseases are characterized as being highly contagious; therefore, these can be easily transmitted among animals and even humans. In addition, intense itching and skin lesions lead to discomfort, consequently causing stress to the animals. Thus, mite control as well as prompt diagnosis and treatment are relevant to manage these skin diseases and ensure animal welfare.

No Brasil, as infecções por hemoparasitas representam uma das principais causas de busca por assistência veterinária em cães. Infecções por bactérias da ordem Rickettsiales que incluem Ehrlichia sp. e Anaplasma sp. tem uma grande participação nessas buscas. Foi objetivo deste estudo elucidar aspectos epidemiológicos regionais e hematológicos de infecções por Anaplasma sp. e Ehrlichia sp, muitas vezes assintomáticas, em cães no município de Jataí-GO.   Os dados deste estudo foram baseados em amostras de sangue de cães ​atendidos no Hospital Veterinário da Universidade Federal de Jataí, em Jataí, Goiás, entre os anos de 2005 e 2017. A observação microscópica da presença de mórulas de Ehrlichia sp. e Anaplasma sp. foi utilizada como critério de positividade. 5.015 animais foram atendidos nesse período e 691 (13,78%) deles foram positivos para a presença destes hemoparasitas. Entre esses animais, 9,23% (463/5015) possuíam mórulas de Ehrlichia sp., e 4,37% (219/5015) apresentavam mórulas típicas de Anaplasma sp., enquanto 0,18% (9/5015) possuíam mórula de ambas as espécies. As fêmeas representaram 57,89% (400/691) dos animais positivos e os machos 42,11% (291/691). 35,02% (242/691) dos animais tinham menos de 1 ano de vida, 54,13% (374/691) tinham entre 1 e 8 anos, e 10,85% (75/691) tinham mais de 8 anos. As fêmeas, com menos de um ano de idade e coinfectadas, apresentaram as alterações mais significativas nos aspectos hematológicos, hematócrito (29%), contagem de hemácias (3 milhões/mm3), contagem de plaquetas (40.000/mm3) e contagem total de leucócitos (16.000 mil/mm3), evidenciando anemia e trombocitopenia. Animais infectados com Anaplasma sp. e Ehrlichia sp., ao mesmo tempo, apresentaram trombocitopenia mais intensa, evidenciada em machos entre 1 e 8 anos (30.000/mm3). As infecções por Anaplasma sp. causaram uma diminuição severa na média da contagem de glóbulos vermelhos, evidenciada em machos (3 milhões/mm3)  e fêmeas com menos de 1 ano (3,79 milhões/mm3).
