Animal transmission of enteric non-A, non-B hepatitis infection to Macaca mulatta by faeco-oral route

Abstract

M. mulatta monkeys were inoculated faeco-orally by enteric non-A, non-B virus to study the development of clinical, biochemical, histopathological and serological changes in the blood and liver. Pooled stool samples positive for putative non-A, non-B viral antigen by micro-ELISA and aggregated viral particles by immune electron microscopy, were administered in two M. mulatta monkeys. Biochemical, histopathological and serological changes were seen in the blood and liver and excretion of 27 nm virus like particles around 27 days of inoculation in the experimental monkey but not in the control animal.
