DEPILATING THRUSH.

confirm his diagnosis by microscopic examination of the hair or 

 scabs. In the ox we may confound thrush with mercurial eruption. 



Prog-nosis. It is favorable in the sense that the cure is always 

 obtained by an appropriate treatment persistently applied. In 

 adult animals of the bovine species it may occur spontaneously, 

 when the scabs fall and remove the hair at the same time, which 

 are the elements at the expense of which the trichophyton feeds 

 and vegetates. We have also observed cases of spontaneous cure 

 in the dog. In young animals localization of the trouble in the 

 neighborhood of the mouth renders the prehension of food difficult 

 and sometimes causes death by inanition. 



Treatment. The prophylactic treatment consists in isolating 

 the sick animals, in cleaning and disinfecting the stables, in destroy- 

 ing the dog-kennels, in warning those persons having the care of 

 the animals of the trausmissibility of the disease to man, giving 

 them sufficient instruction to preserve them from it. 



The curative treatment comprises two principal indications. We 

 must: 1. Thoroughly clean the diseased regions and remove the 

 scabs with green soap. 2. Apply parasiticide agents upon the 

 parts which have been thus prepared. We have the choice among 

 many remedies: cresol, carbolated creosote, naphthol, camphor or 

 iodoform ointments, with tar (1 : 10), with biniodide of mercury, 

 mercurial ointment (we must avoid the use of these latter prepara- 

 tions in the ox) ; iodine tincture (1 : 1-5 of alcohol), salicylic acid 

 and alcohol (1 : 10), alcoholic solution of sublimate or sublimate 

 ointment (1 per cent.), etc. In cases of localized thrush, cresol 

 ointment, tincture of iodine, and an alcoholic solution of salicylic 

 acid have always given us good results. 



No matter what remedy may be used, it must be applied several 

 times daily upon the affected surfaces. 



Pavus : Favous Thrush. 



Etiology. Also called chicken thrush, comb thrush, white comb. 

 This disease is due to a mycelium discovered by Schœnlein in 1839, 

 and designated later by Remak Achorion Schœnleinii, It is rare 

 in the horse, quite frequent in the dog and cat ; it is sometimes 

 found in the rabbit and the mouse. Among the Gallinaceae, the 

 foreign breeds, the Cochin China and Brahma races, are mostly 

 affected. It is transmissible from animals to man and from man 

 to animals (hereditary favus; Erbgrind). The cat contracts it
