Candida glabrata Septicemia in a Piglet / Candida glabrata Septicemia in a Piglet

ABSTRACT

Background: Candida organisms are ubiquitous pathogens that may cause mucosal or systemic infection in humans and animals. Candida albicans was the main Candida specie associated with cases of systemic candidosis, and Candida glabrata is the second most isolated in those cases. In animals there are few reports of candidosis. In pigs C. albicans was described as mucocutaneous disease affecting oral mucosa, esophagus and aglandular stomach of pigs affected by porcine circovirus type 2. Systemic invasion by Candida species in pigs is rare. This report describes the pathological changes observed in a case of systemic candidosis due to C. glabrata infection in a piglet. Case In a nursery facility with 500 piglets a 47-days-old piglet showed lateral recumbency that progressed to inability to stand, paddling and death. In the necropsy it was observed valvular vegetative endocarditis in the left atrio-ventricular valve and in the kidneys multifocal to coalescing whitish foci in the sub-capsular and in the cut surface. Microscopical examination of the cerebral cortex, brain steam and cerebellum revealed multifocal random necrotic suppurative focci surrounded by mononuclear cells, epithelioid and multinucleated giant cells together with discret linfoplasmocitic meningitis. In the kidneys there was embolic suppurative nephritis with multifocal abscesses in renal parenchyma, characterized
