It seemed to me that in any study of human scabies, volunteers willing to suffer infection were required.
In its extreme form scabies can develop into a severe hyperkeratotic form where several thousands of mites can be found in the lesions.
The classical method for the diagnosis of scabies is by microscopical demonstration of the mites and their eggs in skin scrapings.
Scabies was obviously a problem of national importance, recognized by the authorities as such.
Lack of parasite-derived material has limited the possibilities to study several aspects of scabies, including pathogenesis and immunity.
On skin diseases, too, the report associated complaints such as impetigo and scabies with ' wrong feeding ' and neglect.
This parasite is a non-burrowing mite and causes a dermatitis that has the characteristics of a hypersensitivity reaction similar to scabies and sarcoptic mange.
My experience with scabies does not make me an enthusiast for such a system.
