TELOSPORIDIA 



Theileria cellii Castellani and Chalmers, 1910. 

 This parasite is found in Macacus pileatus in Ceylon, in bacillary and pear- 

 shaped forms, lying side by side in the same erythrocyte. The development 

 has not been traced. 



Theileria buffali Neveu-Lemaire, 191 2. 

 This parasite was discovered by Shein in 1908 in the buffalo in Nha-Trang 

 in Indo-China, and is seen in two forms — an ovoidal, which is most frequently 

 met with, and a bacillary. Its m.ode ol transmission is unknown. 



Genus Nieollia Nuttall. 



Definition. — Oval or pear-shaped parasites, with an oval nucleus with two 

 karyosomes, one near the centre and another close to the surface of the body, 

 with quadruple division. 



Nieollia quadrigemina Nicolle, 1907. 

 This parasite is found in Ctenodactylus gondii in North Africa, and Nuttall 

 and Graham-Smith point out that its method of division and its chromatin are 

 so peculiar that its position is doubtful. 



Genus Nuttallia Fran9a, 1909. 



Definition. — -Oval or pear-shaped parasites with multiplication in the form 

 of a cross. 



Type Species, — Nuttallia equi Laveran, 1899. 



Nuttallia herpetedis Fran9a, 1908. 

 N. herpetedis is found in considerable numbers in Herpesies ichneumon L., 

 the mongoose, as small spheres, with the chromatin arranged as a cross, or 

 as pyriform shapes, or in fours arranged in cross form. 



Nuttallia equi Laveran, 1899. 

 Synonym, — Piroplasma equi Laveran, 1899. 



Nuttallia equi is the parasite of piroplasmosis in horses, mules, donkeys, and 

 zebras in Africa, Germany, Italy, and Venezuela. 



The disease appears to have been first differentiated by Wiltshire, in 1883, 

 as anthrax fever, which name was changed to biliary fever by Hutcheon. 

 The parasite was first seen by Guglielmi, in Italy, in 1899. 



It differs from P. canis in existing in large and small spherical forms, in 

 large and small pyriform shapes, in large and small rod-like bodies, in rosettes 

 of four, and sometimes as free flagellate forms. Koch believes that this list 

 includes two different types of parasite — one of parasites arranged in groups 

 of four, and the other like P. canis. 



It is very difficult to inoculate, and is believed to be spread by the blue 

 tick {Eurhipicephalus decoloratus) . 



The incubation period is not known. The disease begins with high fever, 

 but becomes subnormal before death. The appetite varies. The animal is 

 very weak, and in the later stages becomes paralytic and comatose. Anaemia 

 and jaundice are noted. The pulse varies, being often weak and irregular. 

 The respirations are accelerated. Bowels often constipated; urine is highly 

 coloured, and hsemoglobinuria may occur. The disease may be acute or 

 chronic. 



In acute cases death may take place in from two to five days, but the 

 mortality is not high. Secondary and terminal infections may take place. 



The post-mortem reveals emaciation and icteric staining, and anaemia of 

 the tissues, enormous enlargement of the spleen, and thin, watery blood. 

 The liver is yellow and congested; the kidneys are enlarged and anaemic; 

 the lymphatic glands are haemorrhagic, as may be the mucosa of the intes- 

 tines. The heart is sometimes enlarged. The lungs are usually normal. 



Other species are N. ninensis Yakimoff, 1910, in Erinaceus europceus ; N , muris 

 Coles, 1914; A^. decumani Macfie, 1915; N. microti Coles, 1914.
