A severe episode of wildlife-derived scabies in domestic goats in Italy

A scabies outbreak, with unusually high mortality and morbidity, occurred in a poorly managed goat flock in north-eastern Italy. The source of infection was traced back to contact with scabietic chamois (Rupicapra rupicapra) within a recognised sylvatic focus of the disease. Spill-over of scabies from chamois to goats is a matter of great concern to resource managers. Currently scabies-free populations of wild Caprinae in the central and western Alps may eventually be exposed to infected goats transported over long distances. Sanitation of the studied flock was obtained following three applications of pour-on moxidectin at an approximate dose of 500 mcg/kg. Follow-up included titration of circulating anti-Sarcoptes antibodies in a labelled avidin–biotin ELISA test. Two operators developed pseudoscabies after handling the infested flock.
