Emphysematous cystitis in feline caused by <em>klebsiella oxytoca</em> multi-resistant producer of extended spectrum betalactamases associated with <em>enterococcus</em> sp. - case report

Abstract

Over the years, resistance to antimicrobials has become one of the world's biggest public health problems. This problem deserves attention not only in medicine but also in veterinary medicine since microorganisms have zoonotic potential. For that reason, this study aims to report a case of feline emphysematous cystitis caused by a multiresistant Klebsiella oxytoca Extended Spectrum Beta-lactamase (ESBL) producer associated with an Enterococcus sp. We treated the animal at the Veterinary Hospital of the Universidade Federal de Mato Grosso, campus Sinop, Mato Grosso, Brazil and the microorganisms were identified by employing morphotintorial characteristics and biochemical tests at the Animal Health Laboratory of the same institution. We performed the antimicrobial sensitivity test using the Kirby and Bauer method, where we identified resistance to several antimicrobial classes. For phenotypic detection of ESBL production in the Klebsiella oxytoca strain, we performed Disk Approximation, Three-dimensional Extract Test and Minimum Inhibitory Concentration tests using the Etest® tape. This case draws attention because they are bacteria commonly isolated in nosocomial infections in humans only and, for that reason, it emphasizes the importance of working with antimicrobial resistance in the concept of One Health
