POULTRY DISEASES AND THEIR TREATMENT 
Island Experiment Station. Coccidia enter 
the digestive tract of the healthy turkey by 
means of food or water infected by the 
excrement of a sick bird. The organisms 
pass along the alimentary canal until they 
reach the ceca, the lining of which they

tioned under post-mortem symptoms. How 
the infection spreads from the ceca to the 
liver is not clear.

fowls, as well as pigeons, sparrows, etc., act 
as hosts for these parasites. Although 
adult fowls have a great degree of resistance
