I^tfi To prevent contagion and reinfection, diseased fowls should be re- moved from the healthy and the quarters subjected to cleaning up and disinfection, especial attention being given to roosts and other places where the fowls are in the habit of Fig. 74.—Cnemidocoptes mutans, male and female (after Osborn, Bull. No. 5, Bureau of Entomology, U. S. Dept. of Agr.). Mange of the Body, or Depluming Mange.—The depluming mite, Cnemidocoptes gallince, is closely related to the mite of foot mange and it may easily be mistaken for the same species where the two forms of mange coexist. The body form usually has its beginning on the back, near the insertion of the tail-feathers. More rarely the head and upper part of the neck are first attacked. From these regions it spreads to adjacent parts of the body. The disease is accompanied by the production of an abundance of epidermic scale§, irritation, and itching which impels the fowl to pluck at the feathers. These easily drop out or are broken off, leaving a bald or partly denuded skin which is but little thickened and remains normally smooth and elastic. The acaricide treatment employed may be the same as for foot mange. Where a number of birds are affected they may be treated by dipping for several successive days in a sulphur bath.
