TELOSPORIDIA 



microns. External surface of sporocyst rough. No oocystic 

 residual body. Each spore contains two typical sporozoites and 

 one or two sporocystic residua. Habitat, man. 



History. — This parasite Was found by Woodcock and Wenyon, 

 in 1915, in the faeces of a British soldier from Gallipoli. It was 

 again found by Roche in 1917 in three cases at Salonika, so that 

 the total infections up to date (1918) are four. 



Distribution. — Shores of the Eastern Mediterranean. 



Pathogenicity, — Unknown, and no attempts so far made to infect 

 animals. 



Eimeria oxyspora Dobell, 1918. 



Definition. — Eimeria with spherical oocyst 36 microns in diameter, 

 with faintly yellow transparent wall, composed of at least two dis- 

 tinct layers, containing four dizoic spores and a small oocystic 

 residue. Spores long, sharply pointed at both ends, 30-32 x 7-5 

 microns. Sporocyst has a tough endospore and deciduous epispore, 

 the remains of which give the spore a frilled appearance. There are 

 two sporozoites in each spore, with pointed anterior and rounded 

 posterior ends, which contain the nucleus. 



History. — The parasite Was found by Dobell in a young man who 

 had been in South Africa, Ceylon, and India. 



Distribution. — Unknown. 



Pathogenicity.— Infection small, but pathogenicity not certainly 

 known, because the patient was infected with L. histolytica and 

 Ancylo stoma. Believed not to be pathogenic.

Definition.— Not at present capable of definition. 



History. — It was first recorded by Gubler in 1858, in a quarryman, 

 aged forty -five, in Paris. This man is said to have died from 

 peritonitis. He suffered from digestive troubles, anaemia, and had 

 an enlarged liver. Post-mortem the liver contained many tumours 

 of a cancerous appearance, in which were numerous ovoid cells 

 or eggs of helminthes, at least four times the size of the largest cells 

 of the surrounding tissue. Some had a distinct double contour, and 

 Were completely filled with granular contents. One end was rather 

 blunter than the other, which showed a slight constriction, and had 

 a small depressed surface, as though an operculum or micropyle 

 were present. 



The second case was found by Dressier of Prague, and consisted 

 of three small nodules in the margin of a human liver. These nodules 

 contained a whitish pulp, which surrounded oval bodies 18-20 microns
