Sarcoptic mange in captive maras: the first known outbreak and complete recovery with colony-wide acaricide treatment

抄録

Among 16 maras housed as a colony at a zoo, two initially showed generalized dermal lesions on the legs, head and abdomen. Approximately 1 month later, following completion of therapy with amitraz, six maras in the same colony, including the two previously diseased animals, showed dermal lesions with severe alopecia and crusting. Sarcoptic mange was diagnosed on skin scrapings on the basis of morphological criteria. The mites were highly mobile and abundant in all cases, and no other causative agents were detected. Colony-wide treatment with ivermectin and prednisolone was administered weekly for a total of four treatments. After therapy was completed in all cohabitants, follow-up scrapings were negative for Sarcoptes scabiei. This report describes the first known outbreak of sarcoptic mange in captive maras and successful treatment with acaricides.
