Healthcare-Associated Infections (HAIs) are infections acquired after procedures or hospital admissions. HAIs are of great relevance to public health due to their impact, and mainly due to the emergence of antimicrobial resistance. Some studies show the presence of HAIs in animals with reports of outbreaks and the presence of multidrug-resistant bacteria. The objective of this work is to report the first record of a multidrug-resistant strain of Staphylococcus pseudintermedius in a case of Healthcare-Associated Infection in a dog in Brazil. A multidrug-resistant strain of Staphylococcus sp. was obtained, isolated from a dog with recurrent skin infections after undergoing oncological surgeries. The isolate was identified as Staphylococcus pseudintermedius with a multidrug resistance pattern to Enrofloxacin, Neomycin, Gentamicin, Tobramycin, Norfloxacin, Tetracycline, Penicillin, Oxacillin, Cefoxitin, Clindamycin, Marbofloxacin, Erythromycin and Sulfamethoxazole+Trimethoprim, in addition, the presence of resistance genes blaZ, mecA, tetM, ermB and norC was detected. Therefore, it is essential to create a hospital infection control committee in the field of veterinary medicine, as well as the implementation of policies. The study highlights the importance of detecting and identifying multidrug-resistant strains, reinforcing the need for preventive approaches in veterinary medicine and ensuring the effectiveness of treatments and promoting the health of all species.
