SWINE PRACTICE 



Lesions. — The skin of the legs of swiue is most frequently affected. 

 The parasite gains entrance to the hair follicles, where it produces 

 inflammation and causes depilation. The inflammatory reaction causes 

 a redness of the skin, hence the name. In a case of long standing the 

 skin is red, thick, wrinkled, cracked, practically hairless, and evolves 

 a peculiar characteristic odor. The disease extends slowly upon the 

 animal body, and it is not uncommon to And only one animal affected 

 in spite of the fact that there are many swine in the same pen.

 ing and wrinkling of the skin. Small pustules and reddening of the skin 

 also characterize this disease. 



Positive diagnosis can be made only by identifying the parasite micro- 

 scopically. 



Treatment. — This condition is practically incurable, at least in so 

 far as our present knowledge is concerned. Affected animals should 

 be sent to slaughter, as this condition does not impair the meat for 

 food. If for any reason the animal is to be kept upon the premises, 

 it should be placed in rigid quarantine.
