SCABIES. 



SYMPTOMS IN JHE OX. 



The symptoms are similar to those in the horse, . The derma- 

 todectes are generally observed about the withers and root of 

 tlie tail, and soon extend to the whole body, except the limbs, 

 causing severe itching, a falling off of the hair, thickening, 

 hardening, and corrugation of the skin, along with cracks or 

 fissures. The animal rubs and licks itself, causing wounds and 

 abrasions, from which an exudate is poured out, , which, along 

 with the (Ubris of the epidermis, forms crusts. 



The symbiotic parasites locate themselves about the base cf 

 the tail and vicinity of the anus, where, unless there is absolute 

 neglect of cleanliness, they remain, causing irritatioa^ad fonnftT' 

 tion of scabs. — (Fleming.)
