Angiostrongylus vasorum infection in foxes (Vulpes vulpes) in Cornwall

A post mortem examination on a young fox which had been observed to be clinically ill revealed a severe infection with Angiostrongylus vasorum. A further 11 foxes were examined and four were infected with the parasite; three of these also had advanced lesions of sarcoptic mange. The cases all occurred outside the previously defined focus of endemic infection for dogs in Cornwall and they appear to be the first recorded cases of A vasorum in foxes in the United Kingdom.
