A high prevalence in red foxes Vulpes vulpes has been reported in many European countries. P plica inhabits the lower urinary tract and is considered to be of low pathogenic significance in dogs mostly causing asymptomatic infections. However a higher level of pathogenicity has been reported in foxes. A severe cystitis associated with numerous bladderworms was found in a captive arctic fox Vulpeslagopus originating from the endangered Fennoscandian arctic fox population. To our knowledge this is the first description of Pplica infection in an arctic fox. Background The arctic fox Vulpes lagopus syn. Alopex lagopus inhabiting the mountain tundra of Fennoscandia Norway Sweden and Finland is regionally threatened to extinction 1 . The main threats today are inter-specific competition with red foxes Vulpes vulpes and low food availability in certain periods due to the lemming Lem-mus lemmus cycle 2 . In addition a small population size in combination with a fragmented structure may convey negative effects related to the smallness itself 3 . As part of the conservation efforts a breeding-in-captivity program was initiated in 1992 at a Swedish breeding center for endangered species The Nordic Ark . The program produced offspring but the foxes were affected by a neurological disease which resulted in the termination of the breeding colony 4 . The foxes of the colony were closely monitored for diseases and thorough postmortem investigations were conducted on the animals that
