The opportunistic Sarcoptes scabiei: a new episode from giraffe in the drought-suffering Kenya

The ubiquitous Sarcoptes mite is unexplainable emerging and re-emerging parasite, threatening biodiversity and human health. When a new outbreak occurs, it is not clear if it is a genuine emergence resulting from a new incidence or apparent emergence resulting from increased detection. In this paper we report, for the first time to our knowledge, an outbreak of sarcoptic mange in giraffes in the wild. Three decaying carcasses and five free-ranging subadult reticulated giraffes were observed to have mange-like lesions in the drought-suffering Wajir Region in North Eastern Kenya, while apparently all sympatric wild and domestic animals were mange-free. Affected giraffes were captured and successfully treated. The possible relations between this outbreak and annual seasons, animal age-classes and sex, and spatial distribution are discussed.
