  • COMMENTS:
    • Bile duct proliferation as a result of either Cryptosporidium parvum or Enterocytozoon bienusi may be seen in macaques which are immunosuppressed as a result of infection with simian lentivirus. In macaques affected with cryptosporidiosis, parasites were occasionaly seen within the pancreatic ducts as well. E. bienusi and Cryptosporidia are both spontaneous infections of the biliary tree in HIV-infected humans as well.
