ABSTRACT

Considered a very frequent and common dermatological condition in the clinical routine of Veterinarians, Canine Superficial Pyoderma (PSC) is considered an infection of bacterial origin, where the agent Staphylococcus pseudintermedius is in more than 90% of the cases as a pathogen causing such disorder. Since in recent years, bacterial resistance has increased exponentially, especially with regard to the misuse of antimicrobials, new therapeutic approaches for the treatment of PSC are necessary, and this is one of the skin conditions where there is a greater prescription of systemic antibiotic therapy., either as a recurrent disease in dogs with a history of atopic dermatitis, or in dogs without atopy. The diagnostic techniques commonly used for these cases are the association of clinical signs (anamnesis) together with cytological findings. As cocoid bacteria with inflammatory cells are observed, the use of bacterial culture for diagnosis is recommended. Regarding the therapeutic protocol to be established, the evaluation of bacterial resistance through sensitivity tests and the expression of its resistance gene are essential, since many bacteria that cause pyoderma have high zoonotic potential, thus triggering a problem not only in veterinary medicine, as well as in public health. Therefore, it is essential to disseminate relevant information about the isolation of the agent, the control and prophylaxis of this pathology, as well as the guidance of professionals about the most appropriate therapy for affected patients, avoiding successive undue treatments, and which can lead to resistance severe bacterial infection in the context of canine skin diseases.
