Comparative survey of canine parvovirus, canine distemper virus and canine enteric coronavirus infection in free-ranging wolves of central Italy and south-eastern France.

摘要: Diseases likely affect large carnivore demography and can hinder conservation efforts. We considered three highly contagious viruses that infect a wide range of domestic wild mammals: canine parvovirus type 2 (CPV-2), distemper virus (CDV) enteric coronaviruses (CECoV). Infection by either one these populations through increased mortality and/or decreased general health. investigated infection in the wolf Abruzzo, Lazio e Molise National Park (PNALM), Italy, Mercantour (PNM), France. Faecal samples were collected during winter, from October to March, four packs PNALM (n = 79) PNM (n = 66). screened for specific sequences viral nucleic acids. To our knowledge, study is first documented report CECoV wolves outside Alaska, large-scale occurrence CPV-2 European populations. The results suggest enzootic population PNALM, but not episodic both areas. did detect CDV. Our findings density spatial distribution susceptible hosts, particular free-ranging dogs, be important factors influencing infections wolves. This comparative an step evaluating nature possible disease threats studied Recent emergence new strains Europe additionally strengthens need proactive monitoring other sympatric species impairing infections.
