cleansed and disinfected, as a serious in- 
flammation will result if the eyes are rubbed 
with infected hands. This is a troublesome 
and risky disease to treat. 
COCCIDIOSIS OF ADULT FOWLS 
The germ of this disease does not usually affect adult fowls 
seriously, but causes severe losses among chickens and 
turkeys 
Symptoms. ‘The external symptoms are 
not very pronounced; there is loss of weight
