[The parasite-host specificity of the itch mite Sarcoptes scabiei (Acariformes: Sarcoptidae) in man and animals (a review of the literature)].

The primary parasitic relations between the itch mite Sarcoptes scabiei (L.) and man are confirmed indirectly by the presence in the family Sarcoptidae of close genera, members of which parasitize primates. Judging from the composition of domestic and wild animals-hosts, the source of their infection with S. scabiei was man that gave rise to numerous forms of mites specific to individual species of hosts or their related groups belonging to different taxonomic ranks. Three types of host relations and, accordingly, forms of sarcoptosis are suggested at the infection from an alien host: pseudosarcoptosis, temporary self-curable and typical lingering sarcoptosis. The ways of reinfection, invasiveness of stages of the mite and clinical picture for each form of the disease are analyzed.
