Background: Candidosis is an opportunistic fungal infection caused by yeasts of the genus Candida, which normally reside on the surfaces of the mucous membranes and in the skin of several animal species and healthy humans; however the fungi can convert into pathogenic microorganisms and result in invasive infections with systemic involvement due to the impairment of the immune system. Systemic candidosis is rare in dogs and few reports of this mycosis are available in literature. Therefore, the objective of this study was to describe three cases of systemic candidosis associated to canine distemper virus in dogs, highlighting the main epidemiological, clinical and pathological aspects. Cases: Three cases of systemic infection by Candida sp. were diagnosed in dogs. The animals predominantly presented neurological clinical manifestations, followed by unspecific alterations with an evolution of 5 to 30 days. Macroscopically, the lesions were characterized by white-yellowish multifocal to coalescent areas surrounded by reddish borders in the kidneys and heart (cases 1, 2 and 3); liver and submandibular lymph node (case 1); and lung (case 2). In the brains of the three dogs were observed multifocal, blackened and/or reddish and friable areas. In case 1, was observed an increased volume of the right carpometacarpal joint, that when cut, released a reddish and turbid content. In case 2, there was deposition of a whitish lumpy material on the epicardial surface, aorta artery, pericardial sac and spleen; infarction on the right testicle, hydroureter, pyelonephritis and hydronephrosis. Microscopically, the lesions consisted of necrossupurative inflammation associated to hemorrhage, vasculitis, congestion, thrombosis, infarction and fungal structures with distinct morphological patterns which included blastoconidia, pseudohyphae and hyphae. The fungal structures were...(AU)
