A. Eimeria in Mammals 



Eimeria stiedae (Lindemann) (Fig. 112). In the biliary epi- 

 thelium of the liver of rabbits, especially young ones. Heavy 

 infection is believed to be the cause of the death of host animals, 

 which may occur in an epidemic form. The oocyst measures 

 about 20 to 40 microns long. 



Eimeria zurnii (Rivolta). In the gut-epithelium of cattle. 

 The oocyst is 13 to 28 microns long by 12 to 20 microns broad. 



Eimeria faurei (Moussu and Marotel) (Fig. 113, a). In 

 sheep and goat. The oocyst is ovoid and measures 20 to 40 

 microns long by 17 to 26 microns broad. 



Eimeria debliecki Douwes (Fig. 113, b). In pigs. The ovoid 

 oocysts vary greatly in size. Length 12 to 33 microns, breath 

 10 to 21 microns.

 zonts; c, d, schizogony; e, macrogametocyte (X950 all after Hartmann); f-h, 

 development of oocyst (X625 after Wasielewski). 



Eimeria canis Wenyon (Fig. 113, c, d). In dogs. The oocyst 

 varies from 18 to 45 microns long by 11 to 28 microns broad. 



Eimeria felina Nieschulz. In cats. The oocysts are colorless 

 and measure 21 to 26 microns long by 13 to 17 microns wide. 



Eimeria falciformis (Eimer) (Fig. 113, e). In mice. The 

 oocysts are subspherical and measure 16 to 21 microns by 11 to 



17 microns. 



Eimeria nieschulzi Dieben. In rats. The oocyst measures 



18 to 26 microns by 14 to 20 microns. 



B. Eimeria in Birds 



Eimeria tenella (Railliet and Lucet) (Fig. 113, /). In the 

 caecum, large intestine, and lower small intestine of chicken.
