Plain-English summary
A group of dogs with ear infections (otitis externa) and skin infections (pyoderma) were tested for a type of bacteria that can resist common antibiotics. Out of 331 samples, a significant number showed resistance to methicillin, a common antibiotic, especially in ear infections. The study found that nitrofurantoin was the most effective antibiotic for treating these infections, working well in 97% of ear cases and 83% of skin cases. This research highlights the growing issue of antibiotic resistance in dogs, particularly in Peru.

Abstract
BACKGROUND: Dermatological infections are the most common cases in the daily pet clinic. Since its discovery in 1990,subspecieshave been reported more frequently in canine otitis externa and pyoderma and even in cases of zoonoses. AIM: Detect the presence ofsubsp.of canine otitis externa and pyoderma, its antimicrobial resistance, and the presence ofAgen. METHODS: Three-hundred-thirty-one swabs from dogs with otitis externa and pyoderma were cultured on bacteriological agar for bacterial isolation and subsequent biochemical and molecular identification. The identifiedsubsp.were evaluated for their antimicrobial susceptibility using the Kirby-Bauer technique, including an oxacillin disk, and subsequently, a PCR was run to identify which ones had theA gene. RESULTS: Thirty-four (22.97%) and twelve (6.56%) isolates were identified assubspeciesfrom otitis externa and pyoderma, respectively. Fluoroquinolones, the most widely used group of antibiotics in Peru, showed a susceptibility of 58.82% (20/34) in cases of otitis externa and 50% (6/12) in cases of canine pyoderma. Meanwhile, nitrofurantoin was the antibiotic with the best efficacy in both cases, with 97% (33/34) in otitis externa and 83% (10/12) in pyoderma. Furthermore, 40% (13/34) ofsubsp.isolated from otitis externa were resistant to methicillin, and 85.29% (29/34) had theA gene. On the other hand, the only methicillin-resistant isolate from pyoderma was also the only one with aA gene. CONCLUSION: This study is the first report ofsubsp.in Peru, finding a higher percentage than reported in other South American countries.
