 GEANDS.

PARASITES OF THE AIR PASSAGES, LUNGS, AND 

 PLEURA. 



Nearly all the domestic animals are subject to parasites of the 

 lower air passages. These give rise to verminous bronchitis in 

 cattle, sheep, horses, swine, goats and camels, to gapes in birds, 

 and to pulmonary acariasis in fowls. The lungs and pleura are 

 invaded by distomum, echinococcus, cysticercus, aspergillus, etc. 

 (See parasites).
