Adenoviral pancreatitis in guinea fowl (Numida meleagris)

SUMMARY. Necrotizing pancreatitis was observed in 2-week-old Guinea fowl submitted for necropsy and histopathology. Intranuclear inclusion bodies seen histologically in acinar epithelium were examined by electron microscopy and found to contain viruses resembling adenovirus. Adenovirus was isolated in embryonated eggs from the pancreata of affected birds. The adenovirus isolated was not neutralized by chicken antisera developed against 10 known serotypes of group 1 avian adenoviruses.
