COCCIDIOSIS 33 



fat globules. The submucosa is in a state of 

 inflammation and round-celled infiltration, and 

 may contaili coccidia. Immature coccidia may 

 also be found in the mesenteric glands. 



In nasalcoccidiosis the nasal and pharyngeal 

 mucous membrane is found to be in a state of 

 catarrhal inflammation covered with an orange 

 colored exudate which contains coccidia. The 

 eustachian tube may also be invaded and the 

 external auditory canal, the middle ear and the 

 tympanum. 



DifiFerential Diagnosis 



Coccidiosis may be mistaken for tuberculosis, 

 pseudo-tuberculosis and cysticercosis, and the 

 only reliable means of differentiation is by the 

 microscope, although the fact that the lesions 

 are confined to the liver and intestine is not 

 suggestive either of tuberculosis or pseudo- 

 tuberculosis, both of which diseases being found 

 to be more generalized. 



Diagnosis during life is determined by the 

 clinical syniptoms and the detection of the par- 

 asite during life, but in the cases of nasal cocci- 

 diosis the fact that it may be only a complica- 

 tion of some other disease should not be lost 

 sight of. 



Treatment 



Prophylaxis is by far the most important 

 and has been fully dealt with imder the caption 

 hygiene.
