2Q2 OTHER GERM DISEASES. 



is Texas fever or, as it is frequently called, the tick fever. This 

 latter name is given to it from the fact that the disease is dis- 

 tributed by means of the cattle tick. Other diseases caused by 

 animal parasites are surra and the tsetse fly disease or nagana, 

 neither of which is found in this country. 



Diseases of Other Animals. Parasitic diseases are found in 

 all animals bred upon the farm, each animal having its own peculiar 

 types. Ordinary fowls have fowl cholera, roup, diarrheal diseases, 

 etc., and turkeys, geese, and ducks have diseases of their own. 

 Even fishes are subject to diseases produced by bacteria of other 

 fungi. It is impossible in this work to consider this subject further, 

 but it is well to bear in mind that the list of parasitic diseases is a 

 long one and is being increased constantly as investigation is being 

 extended.
