[Taxonomical approach to scabies mites of human and animals and their prevalence in Korea].

Three types, hitherto commonly known as varieties of Sarcoptes scabiei (Linnaeus, 1758) were collected from scabietic patients, pigs and dogs to confirm their taxonomic status. As a result, we consider that the mites of human and pig scabies are different subspecies [S. scabiei scabiei (Linnaeus, 1758) and S. scabiei suis Megnin, 1880, respectively], and that of dog scabies is a different species, S. canis Gerlach, 1857. Infestation rate of human scabies in Korea peaked in 1981-1982 and showed nearly 10% of prevalence rate among outpatients of the dermatology clinic, but decreased dramatically during the past ten years and now lowered below 1% since 1990. On the other hand, dog scabies seems to be increasing recently.
