THE MOST COMMON DISEASES OF SWINE Z^()^ 



STRONGYLUS ELONGATUS 



"This species lives in the lungs and air passages. It 

 is about I to i/<2 inches long. They often occur singly 

 or several together. When they are numerous they set 

 up great disturbance, often resulting in the death of the 

 liost. The first symptom of the disease is a cough, us- 

 ually slight at first, but soon becoming very distressing, 

 and the pig shows signs of suffocation, which sometimes 

 takes place, or inflammation may set in and carry the 

 animal oft". This disease is often taken for catarrh or 

 some other respiratory trouble, and it is very difficult to 

 diagnose unless a worm which has been coughed up may 

 be seen protruding from the nose. 



"Treatment is not easy. Small quantities of turpen- 

 tine injected into the nostrils may reach the worms. Tur- 

 pentine given in teaspoonful doses three times daily will 

 sometimes be of use, as the turpentine is partly eliminated 

 by the lungs. Inhaling the fumes of carbolic acid is also 

 useful. 



SPIIIOPTERA STRONGYLINE 



"There are a number of small, whitish or reddish 

 round worms which taper somewhat toward the an- 

 terior end, or toward both ends. The head is small, with 

 small papillae or naked ; the male grows to about >4 inch 

 long o- more; the female r-3 inch or more; it lives in 

 the stomach of the pig, but generally does not produce 

 any serious disease. The fluid extract of spigelia and 

 senna in }i ounce doses, given every four hours until 

 purging ensues, usually dislodges them.
