208 PARASITOLOGY. 
Symptoms.—tLoss of appetite, elevation of temper- 
ature, 102° to 105°; sunken eyes; grinding of teeth; 
later, fetid diarrhoea; feces may be streaked with 
blood; may prove fatal in one or two days, or patient 
may live two or three weeks. 
Treatment.—Intestinal antiseptics, as eucamphol or 
kreso solutions. 
CoccipIUM TENELLUM. 
Distribution —Found throughout the United States. 
Description—tThe resting stage is a small micro- 
scopic oval cell containing a small nucleus. They have 
a double enveloping membrane and a granular con- 
tent. The size varies greatly, being from 15 to 28 
microns long and 15 to 22 microns broad. 
Life Cycle—The oocyst divides into four sporob- 
lasts and these in turn into two sporozoits. When 
these sporozoits penetrate the epithelial cells they 
form first trophozoites then schizonts, which gives 
rise to several merozoites. 
Animals Infested —Chicks. 
Parts Infested—Caecum and small intestines. 
Conditions Produced—A local point of inflamma- 
tion where they invade the mucosa which is followed 
later by ulceration. It produces a condition in chicks 
known as white diarrhoea. 
SARCOSPORIDIA (Sporidum—a spore) 
(Sarx—flesh). 
This order, Sarcosporidia, belongs to the class 
Sporozoa, and includes single-celled parasites that 
infest the muscle structures.
