title: Experimental non-A, non-B hepatitis in chimpanzees: light, electron and immune microscopical observations.
abstract: Two chimpanzees (Pan troglodytes) were inoculated and cross-challenged with a fibrinogen and factor VIII preparation, respectively. Successful non-A, non-B (NANB) infection was documented by biphasic elevations of aminotransferases (ALT), concomitant hepatitic reactions and typical electron microscopic alterations, the most consistent being dilatation of the endoplasmic reticulum, as well as tubular and sponge-like cytoplasmic inclusions in the absence of nuclear virus-like particles. An anti-nuclear (anti-DNA) antibody of the IgM class in one of the chimpanzees simulating an antiviral antibody is described.
