Intestinal cryptococcosis in a common marmoset (Callithrix jacchus).
A five-year-old female common marmoset (Callithrix jacchus) died after a one-month clinical course of nonspecific signs. Pathologic findings were acute diffuse fibrinonecrotizing enteritis and granulomatous endolymphangitis of intestinal and mesenteric lymphatic vessels. Both lesions were associated with a marked proliferation of Mayer's mucicarmine-positive, 4 to 15 microm yeasts that were surrounded by a wide clear halo. The infection was probably acquired by oral route. Other findings included moderate multifocal granulomatous and necrotizing hepatitis and mesangial nephropathy. Although the immunological status of this marmoset was unknown, cryptococcosis might induce primary lethal intestinal infections in callitrichids.
