ABSTRACT
We describe gross pathology, histopathology, ultrastructure, and molecular characterization of skunk adenovirus 1 (SkAdV-1) in 3 ferrets (Mustela putorius) submitted to the Infectious Diseases Laboratory, Zoo and Exotic Animal Pathology Service at the University of Georgia. Case 1 came from a cohort with a 6-week history of multiple ferrets with respiratory disease and mortality. Cases 2 and 3 were submitted 19 days later; they died 3 days after arrival at the vendor's facility. Histopathological evaluation found evidence of suppurative bronchopneumonia, with intralesional gram-positive cocci in case 1. The others had evidence of subacute multifocal histiocytic and lymphoplasmacytic interstitial pneumonia. Viral isolation, polymerase chain reaction (PCR), and DNA sequencing identified SkAdV-1 in lung tissue. In situ hybridization confirmed adenovirus within the lung lesion, and adenovirus particles were visible under an electron microscope. This is the seventh species in which SkAdV-1 has been identified. Cross-species transmission events have important implications for wildlife management and multispecies facilities.
