Histopathological characterization of nephritides in the brown capuchin monkey, Cebus apella (Primates : Cebidae)

The renal lesions are of special importance in the captive primates. The mo st commonly pathologies are: pyelonephritis, nephrocalcinosis, glomerulonep hritis, congenital malformations, hydronephrosis and functional diseases. W e report the histopathological study of renal lesions of five cases of deat hs in Cebus apella (Primates) of the Argentinean Primate Center. The ages o f the monkeys were from 4 months to 15 years old. Microscopically, we have observed principally acute diffuse proliferative glomerulonephritis, hilar mesangio proliferative glomerulonephritis, extracapilar glomerulonephritis with crescents, chronic interstitial nephritis and chronic pyelophritis.
