THE TELOSPORASIDA AND THE COCCIDIA PROPER 



oocysts of E. ninakohlyakimovae and 

 100, 000 oocysts of E. faiirei. There was 

 no decrease in water consumption. Clin- 

 ical signs appeared on the 9th day after 

 infection and ended about the 22nd day. 

 One out of the 4 lambs died on the 15th 

 day. There were decreases in percentage 

 of feed protein digested and inorganic 

 serum phosphorus, increases in serum 

 globulins and blood glucose, and no sig- 

 nificant changes in total serum protein, 

 blood hemoglobin and hematocrit values. 

 Oocysts of both species appeared in the 

 feces on the 15th day, increased until the 

 21st day and then decreased gradually. 



Balozet (1932) observed a case of 

 muco-sanguineous diarrhea followed by 

 death in a naturally affected adult goat, 

 and produced the disease experimentally 

 in 2 newborn kids. A mucous diarrhea 

 appeared on the 22nd day after infection, 

 became bloody, and persisted until about 

 the 39th day. 



Remarks : In one of the very few 

 cross-transmission experiments attempted 

 with sheep and goat coccidia, Balozet 

 (1932) was unable to infect a recently 

 weaned lamb with E. numkohlyakimovae 

 from a goat, altho he did infect 2 newborn 

 kids. He thought the lamb was too old. 



EIMERIA PALLIDA 

 CHRISTENSEN, 1938 



tible and there is no micropylar cap. The 

 oocyst wall is thin, homogeneous, color- 

 less to pale yellow to yellowish green, 

 appears fragile and pallid, and is com- 

 posed of 2 layers of which the outer is 

 half as thick as the inner, with a single 

 dark refraction line marking its inner edge. 

 An oocyst polar granule and oocyst resi- 

 duum are absent. The sporocysts are 

 ovoid, without a sporocyst residuum. The 

 sporozoites lie lengthwise, head to tail, 

 in the sporocysts, and contain a spherical 

 globule at each end. The sporulation time 

 is 1 day. 



Life Cycle : Unknown. 



Pathogenesis : Unknown. 



Remarks : In describing E. pallida, 

 Christensen (1938a) said that it differed 

 from E. parva is being narrower, pale, 

 inconspicuous and colorless, and in having 

 only a single black refraction line on the 

 inner surface of the oocyst wall instead of 

 2 black refraction lines, one on each side 

 of the inner wall. However, Kotlan, Pel- 

 lerdy and Versenyi (1951) considered E. 

 pallida a synonym of E. parva. 



EIMERIA PARVA 



KOTLAN, MOCSY AND VAJDA, 1929 



Synonyms : Ei»ieria galouzoi {pro 

 parte). 



Host : Sheep. 



Location : Unknown. Oocysts found 

 in feces. 



Geographic Distribution : North 

 America. 



Prevalence : Christensen (1938a) 

 found this species in 10% of 100 sheep 

 from Maryland and Wyoming. 



Morphology : This species has been 

 described by Christensen (1938a). The 

 oocysts are ellipsoidal, 12 to 20 by 8 to 

 15^ with a mean of 14. 2 by 10, O^L . Their 

 length-width ratio is 1 . 2 to 1 . 7 with a 

 mean of 1. 43. A micropyle is impercep- 



Hosts : Sheep, goat. Rocky Mountain 

 bighorn sheep, Barbary sheep {Ammotra- 

 gus lervia), Siberian ibex {Capya ibex 

 sibirica), roe deer. 



Location : Schizonts are found thru- 

 out the small intestine, and gametes and 

 gametocytes in the cecum, colon and small 

 intestine. 



Geographic Distribution : Worldwide. 



Prevalence : This species is common 

 in sheep, less common in goats. Chris- 

 tensen (1938a) found it in 50% of 100 sheep 

 from Idaho, Maryland and Wyoming. Jacob 

 (1943) found it in 52% of 100 sheep and 9% 

 of 11 goats in Germany; he also found it in
