Angiostrongylus vasorum infection in red foxes (Vulpes vulpes) in southern Italy

Abstract

Angiostrongylus vasorum (Nematoda: Angiostrongylidae) infection was detected at post-mortem examination in the pulmonary arteries and hearts of 34/102 (33,3%) of red foxes (Vulpes vulpes) from the Campania Region in southern Italy. Pathological changes consisted of granulomatous interstitial pneumonia caused by larvae and intravascular pulmonary adult nematodes. These changes confirm that angiostrongylosis infection in red foxes has a mainly chronic course, in which the infected host may disperse parasite larvae in the environment over its lifetime. Results suggest that the life cycle of A. vasorum is well established in the red fox in the Campania Region representing a potential infection risk for dogs.
