PARASITES OF THE HOG. 



STRONGYLUS ELONGATUS. 



This parasite is located in the lungs of hogs. They are gen- 

 erally found in the terminal part of the main bronchium in the 

 posterior lobe of one or both lungs. Other air tubes are occa- 

 sionally infested. The male is eight to nine inches in length, the 

 female one to one and a half. They have curled tails. Pigs in- 

 fested by these worms thrive badly, aad may die. 



Treatment. — These parasites may be destroyed by placing 

 the herd in a close pen and compelling them to inhale the fumes 

 of burning sulphur once a day for three days. When the hogs 

 begin coughing they may be released.

 male is about one and a half inches long, and is curved in a

 When these worms are present, they may cause an inflammation 

 of the large intestines, with costiveness or diarrhoea and a rapidly 

 advancing bloodlessness. 



Teeatment. — Give a half ounce of the oil of turpentine, and
