FUNGOID DISEASES OF ANIMALS iii 



especially about the face and neck, devoid of hair 

 and varying in size from a fraction of an inch to 

 several inches in diameter. The skin on these bare 

 surfaces is wrinkled, encrusted, and scabbed in ap- 

 pearance. In the earlier stages small bladders are 

 seen from which an evil-smelling substance exudes. 

 These dry up, forming the bark or crust of greyish- 

 brown leathery scales mentioned above. 



Cause. — The bladder-like swellings and loss of 

 hair are caused by the parasitic fungus Oidiuin ton- 

 surans, of which there appear to be several varieties. 

 It grows readily on blood serum, where it forms, on 

 the hyphse, chains of roundish oval conidia, w^hich 

 spread the disease. Whether this fungus is identi- 

 cal with the one found on human beings is still an 

 open question. 



Remedial Afeasures. — Clean the parts well by 

 scraping and brushing and afterwards apply one of 

 the following dressings, which must be repeated 

 should occasion require : — 



[a) Train oil 5 parts, sulphur i part. 



i^b) Soft soap 5 parts, sulphur i part. 

 . [c) Olive oil 8 parts, creosotell i part. 



Levie recommends the following : wash well with 

 warm water, washing soda, and soft soap, rub off 

 the crusts with emery paper, and next day when dry 

 paint the parts with the following: — 



I oz. Sir Wm. Burnett's disinfecting fluid, 24 

 oz. water (shake well before using).
