This report details the mortality and pathological findings of Duck viral enteritis outbreaks in domestic muscovy ducks in Pennsylvania.
Alerts clinicians to DVE risk in muscovy ducks; leaves open needs for host-specific surveillance and control studies.
Duck viral enteritis (DVE) outbreaks occurred at two different locations in Pennsylvania in 1991 and 1992. In the first outbreak, four ducks died out of a group of 30 domestic ducks; in the second outbreak, 65 ducks died out of a group of 114 domestic ducks, and 15 domestic geese died as well. A variety of species of ducks were present on both premises, but only muscovy ducks (Cairina moschata) died from the disease. On necropsy, gross lesions included hepatomegaly with petechial hemorrhages, petechial hemorrhages in the abdominal fat, petechial hemorrhages on the epicardial surface of the heart, and multifocal to coalescing areas of fibrinonecrotic material over the mucosal surface of the trachea, esophagus, intestine, and cloaca. Histologically, the liver had random multifocal areas of necrosis and eosinophilic intranuclear inclusion bodies in hepatocytes. DVE virus was isolated and identified using muscovy duck embryo fibroblast inoculation and virus neutralization.

Davison et al. (1993) conducted a case report in Duck viral enteritis (DVE) (n=159). Duck viral enteritis (DVE) infection was evaluated on Mortality and pathological lesions. Duck viral enteritis outbreaks in Pennsylvania caused significant mortality exclusively in muscovy ducks, presenting with hepatomegaly, petechial hemorrhages, and fibrinonecrotic lesions.
