88 DISEASES OF THE HOG. 



truncated and provided with an oblique bursa; in 

 the female it is elongated and slender, ending in a 

 fine point; the genital opening is near the posterior 

 end. The history of this worm is not known. It 

 does not seem to do much harm. The usual treat- 

 ment for worms is nearly always effectual in bring- 

 ing them away. I have seen quite a number of 

 them mixed with other worms in the feces of a hog 

 that had been treated for worms. 



STRONQYLUS ELONQATUS. 



This species live in the lung and air passages of 

 the pig. This worm is about one to one and one- 

 half inches long. They often occur singly or sev- 

 eral together. When they are numerous they set 

 up great disturbance, often resulting in the death 

 of the host The first symptom of the disease is a 

 cough, usually slight at first, but soon becoming 

 very distressing, and the pig shows signs of suffo- 

 cation, which sometimes takes place, or inflamma- 

 tion may set in and carry the animal off. This dis- 

 ease is often taken for catarrh or some other res- 

 piratory trouble and it is very difficult to diagnose 

 unless a worm which has been coughed up may be 

 seen protruding from the nose. 



Treatment: This is not easy in the pig. Small 

 quantities of turpentine injected into the nostrils 

 may reach the worms. Turpentine given in tea- 

 spoonful doses three times daily will sometimes be 

 of use, as the turpentine is partly eliminated by 

 the lungs. The inhalation of the fumes of carbolic 

 acid is also useful.
