Importance of canine distemper virus (cdv) infection in free-ranging iberian lynxes (lynx pardinus).

摘要: Canine distemper virus (CDV) is a morbillivirus that the etiological agent of one most important viral diseases affecting canids and an expanding range other carnivores. Using real-time RT-PCR, CDV RNA was detected in organs Iberian lynx (Lynx pardinus) found dead Donana National Park, Southwestern Andalusia, Spain. This finding may be great importance for conservation species; at present critically endangered wild felid. The aim study to elucidate significance population. High loads were evident lynx, suggesting involvement its death. When carnivores from same region analyzed by stone marten (Martes foina) positive. Phylogenetic analyses demonstrated high identity two CDVs close relationship European dog lineage CDV. Antibodies 14.8% 88 tested free-ranging lynxes. sample seroprevalence significantly higher lynxes Natural Space (22.9%) than Sierra Morena (5%). red fox (Vulpes vulpes) also seropositive. In conclusion, population, especially region, with sporadic cases disease. To reduce infectious pressure on this mass vaccination should considered.
