DEEP PYODERMA FOR Corynebacterium pseudotuberculosis IN AGOUTI

Abstract

Bacterial skin diseases represent a significant ratio of rodents’ pathologies. However, in agoutis (Dasyprocta sp.), a middle-sized rodent with geographic distribution from Central to South America, reports on isolated bacterial agents of cutaneous inflammatory processes are not observed. The present study aimed to describe a case of deep pyoderma by Corynebacterium pseudotuberculosis in an agouti (Dasyprocta sp.). The agouti (Dasyprocta sp.) presented the description of cutaneous injury and it was submitted to physical examination. After that, antibiotic and anti-inflammatory were prescribed. The animal died when the treatment was interrupted, and it was directed to necropsy. Over there, samples for bacterial culture and histopathological examination were obtained. The findings of necropsy were: alopecia, erythema, cellulitis, crusts and ulcers, on the ventral side of the head. The tegument’s cut surface disclosed purulent and caseous secretion. The bacterial culture isolated the C. pseudotuberculosis. The cutaneous histopathology diagnosid deep pyoderma. Because of the reduced knowledge about agoutis pyoderma (Dasyprocta sp.), further investigations on the disease’s etiopathogeny are necessary.
