The lesions are essentially the same as those of verminous 

 bronchitis in sheep, the number of parasites determining the ex- 

 tent and violence of the morbid process. Collapse and congestion 

 of particular lobules are not uncommon and Gratia describes the 

 appearance as of miliary tubercles, resembling those seen in sheep 

 with the strongylus rufescens. These are due to the encystment 

 of the female worm or of the ova and embryos in the air sacs and 

 cells. Invasion of the lungs by numerous cysticercus tenuicollis 

 may give rise to similar pneumonia, which may be differentiated by 

 the microscope. (Leuckart, Zschokke, Boudeaud). 



Symptoms are often obscure. Unthriftiness, lack of condi- 

 tion, anaemia and emaciation are shown especially in young pigs, 

 and if associated with a paroxysmal cough, at first hard and later 

 moist and rattling, or even suffocating, and if this shows in a 

 large proportion of the herd independently of any change of 

 weather, damp bed or other cause, there is a strong presumption 

 of lung worms. This may be confirmed by finding embryos or 

 adult worms in the frothy expectoration, or, in fatal cases, in the 

 bronchia. Death may be from suffocation, or from progressive 

 emaciation and marasmus. In the majority of cases, however, 

 the disease subsides and the patient recovers, so that its true 

 nature is never discovered, 



Treatment is the same as for calves or lambs, tracheal injec- 

 tions of benzine or oil of turpentine being especially to be recom- 

 mended. (Block). 



Prevention is to be sought in a change of pig-pen and range, 

 and the careful avoidance of pond, running or well water which 

 may have become contaminated by the affected herd or others, or 

 better still in boiling all water before it is supplied to them. 

 Such measures are especially necessary in the case of young pigs, 

 which almost alone furnish fatal cases. These may be kept on 

 fresh ground, or, if the sows are affected, on wooden or cement 

 floors, the food should be moderately salted, and they should be 

 removed from the sows and all mature swine as soon as they are 

 weaned,
