Resumo

Background: During the last years, there is a global concern about the increasing levels of antimicrobial resistance in human and veterinary medicine. Klebsiella oxytoca isolates are ubiquitous in nature, including surface water, soils, sewage, and plants. Klebsiella oxytoca is a nosocomial pathogen in humans but few studies reported as a pathogen in dogs and cats. Antimicrobial resistance represents a serious problem due to the increasing prevalence of extended-spectrum β-lactamaseproducing K. oxytoca isolates. The aim of the present study is describe the first clinical case of disseminated dermatitis in a dog caused by K. oxytoca multidrug resistant and the importance of correct protocol treatment.Case: A 4 year-old dog, Shih-tzu, female showed a disseminated dermatitis displayed generalized alopecia, with seborrheic aspect and pruritus, in non-nosocomial conditions in the city of São Paulo. Skin samples were collected and sent to a veterinary microbiology laboratory for bacterial identification and antimicrobial susceptibility testing (AST). The tests demonstrated a Gram negative bacilli, oxidase negative, catalase positive, non motile, DNase negative, glicose fermentative, lactose positive in MacConkey agar. In all biochemical complementary tests the results were indole positive. The strain of K. oxytoca was tested for resistance to the following antibiotics: amikacin, amoxicillin-clavulanic acid, ampicillin, cephalexin, cephalosporin, chloramphenicol, ciprofloxacin, doxycycline, enrofloxacin, gentamicin, imipenem, levofloxacin, marbofloxacin, meropenem, neomycin, sulfamethoxazole/trimethoprim and tetracycline. The AST result demonstrated a resistant Klebsiella oxytoca for 76,4% of tested antibiotics and sensitivity to few antibiotics such as meropenem, imipenem, neomycin, amikacin, sulfamethoxazole and trimethoprim. The initial treatment was performed with meropenem, once the in vitro susceptibility to this antibiotic was demonstrated.[...](AU)
