New techniques for an old disease: sarcoptic mange in the Iberian wolf.

摘要: Sarcoptic mange, a parasitic skin infection caused by the burrowing mite Sarcoptes scabiei, has been reported in over 100 mammals, including humans. In endangered species, mange causes conservation concerns because it may decimate isolated populations and contribute to extinction. The Iberian Peninsula still maintains one of largest wolf (Canis lupus) Europe. Iberia, sarcoptic is endemic red foxes (Vulpes vulpes) first confirmed cases were recently reported. However, knowledge on S. scabiei wolves scarce sampling difficulties inherent research species. order describe epidemiology infer implications, this study combined traditional laboratory techniques with revision carcass pictures taken field biologists original information obtained camera trapping. A total 125 necropsies 8783 camera-trap days allowed insights into between 2003 2010. Living mites detected 19% fresh carcasses. Alopecic (delayed) type IV hypersensitive response reactions observed, while parakeratotic lesions infrequent. number per ranged from 1 78, had negative correlation percentage alopecic skin. No effect sex prevalence was found. Yearlings showed lower probability present mange-compatible than pups or adults. Wolves kidney fat index apparently healthy ones. ELISA testing 88 sera yielded an antibody 20%. Photo-trapping recorded since peak 2008. registered camera-traps during year correlated previous year. This large survey wolf. Necropsy data, alopecia as main feature slight body condition, trends derived trapping coincided showing rather low stable situation disease its host, suggesting that parasite currently not major threat for population. more needed assess aspects such pup survival.
