title: An evaluation of the application of infrared thermal imaging to the tele-diagnosis of sarcoptic mange in the Spanish ibex (Capra pyrenaica).
abstract: The application of infrared thermal imaging to the diagnosis of sarcoptic mange in the wild Spanish ibex (Capra pyrenaica) was evaluated. Seventy-three ibexes (35 males, 38 females) of varying ages were studied. Each animal was observed using conventional binoculars (OT) to detect lesions characteristic of mange. Infrared thermography (IR) was then performed and the resultant image judged negative or positive. The distance from the thermograph to the animal was measured, and the animal killed. Skin samples were taken for mite detection by routine laboratory diagnosis (LAB). The most sensitive and specific technique for the tele-diagnosis of sarcoptic mange in the Spanish ibex is OT, as it permits diagnosis over greater distances than IR, which sensitivity is impaired at distances >100m. When disease prevalence is low, such as in initial and final phases of an epidemic, a more sensitive technique would be valuable in detecting all affected animals.
