RESISTÊNCIA ANTIMICROBIANA COMO DESAFIO NO TRATAMENTO DE DERMATOPATIAS EM CÃES

Abstract

Antimicrobial resistance represents one of the greatest and most current challenges in veterinary medicine, especially in the management of skin diseases in dogs. These skin conditions, often associated with opportunistic pathogens such as Staphylococcus pseudintermedius, Staphylococcus aureus, and Pseudomonas aeruginosa, have shown increasing rates of resistance, complicating treatment and favoring relapses. The objective of this study was to analyze, through an integrative literature review, the resistant and multidrug-resistant agents present in canine skin diseases, as well as the antimicrobials involved in resistance and the main recommendations for controlling this process. The methodology consisted of a bibliographic survey of national and international databases, considering recent publications addressing antimicrobial resistance in dogs with skin conditions. The results showed a significant prevalence of multidrug-resistant microorganisms, particularly Staphylococcus pseudintermedius and Pseudomonas aeruginosa, with high rates of resistance to ampicillin, amoxicillin plus clavulanate, clindamycin, enrofloxacin, and amoxicillin plus clavulanate, and trimethoprim plus sulfamethoxazole, respectively. This reinforces the importance of prescribing antimicrobials, always in conjunction with microbiological diagnosis, establishing therapeutic protocols based on updated local data on resistance, and communicating with the owner, reinforcing the importance of treatment adherence. Therefore, antimicrobial resistance in canine skin diseases is a challenge that requires integrated actions among veterinarians, researchers, regulatory agencies, and owners for an effective approach, appropriate clinical management, and potentially reducing the spread of resistant strains.
