Abstract

Angiostrongylus vasorum was identified in the lungs of a red fox (Vulpes vulpes) from West Virginia, United States (US), indicating a new geographical location for this metastrongylid nematode. The fox was euthanized and submitted for necropsy after displaying erratic behavior. We did not detect rabies virus or canine distemper virus from the fox. We observed bronchopneumonia associated with A. vasorum infection disseminated in both lungs. In addition, protozoal meronts were observed in the liver, spleen, and mesenteric lymph node, and were identified as Hepatozoon canis. Lymphoid depletion was also observed in the spleen and mesenteric lymph node. In addition to A. vasorum and H. canis infections, Eucoleus aerophilus eggs and adult worms were observed in the lungs of the fox. Severe lesions associated with A. vasorum infection were observed in the lungs and these were determined to be the likely cause of morbidity; however, synergistic effects among the multiple infections detected in this fox cannot be ruled out. This is the first report of an autochthonous A. vasorum infection in the US and from outside of Newfoundland Canada, the only place in North America where the parasite is known to be endemic. Additionally, this is the first report of a H. canis infection in a red fox from the US.
