PARASITOLOGY. 205 
Distribution —Found in America and Europe. 
Description These protozoa are elliptical micro- 
scopic bodies from twelve to fifteen microns long by 
seven to ten microns broad, and are found in pairs. 
In the center is a small granular nucleus. 
Life Cycle—The protoplasm of the parent cell di- 
vides into four elongated spores, which are capable 
of invading new tissues, and which develop into 
mature form. 
Arimals Infested—The ox, dog and rabbit. 
Parts Infested —Air passages and bowels. 
Condition Produced.—Catarrhal inflammation of 
testinal mucosa, lodged immediately beneath the 
epithelial cells; they are not attributed as causing 
serious disturbance. They have been found in the 
intestinal mucosa of healthy dogs. 
Coccipium PerRForANns (Per—through) 
(Forare—to bore). 
Distribution—Reported in European countries; 
first reported in cattle in 1877. 
Description.—Rather ovoid in shape, measuring 
twentv-five to thirty-five microns long and fourteen 
to twenty microns broad; the adult produces corpus- 
cles which invade the tissue and develop to full adult 
size. 
Animal Infested —The dog. 
Parts Infested.—Intestines. 
Condition Produced—tThey are found infesting the 
the upper air passage; thickening and inflammation 
of the mucosa of the stomach and the intestines; the 
mesenteric lymph glands, liver and spleen are also in 
a state of inflammation. The lesions all contain the 
coccidia.
