Comparative pathological and immunohistochemical features of sarcoptic mange in five sympatric wildlife species in Northern Spain

This study collects pathological information concerning sarcoptic mange in sympatric red deer, roe deer, chamois, wolf and red fox from Northern Spain, and discusses reported variations in the response from the different species against Sarcoptes scabiei. Wolf is the only studied species which shows prevalence of the hypersensitivity (alopecic) response to the detriment of the hyperkeratotic form, usually observed in ungulates and fox. The present work shows the use of immunohistochemistry as a valuable tool for the study and diagnosis of sarcoptic mange in those species whose immune response or stage of infestation limits the number of detectable mites, not an unusual difficulty faced when working with sarcoptic mange in wildlife species.
