372 SPOROZOA. 



Researches of Ashworth (1923) apparently prove that the 

 organism belongs to the fungi, and ought to be classed among 

 the Phy corny cetes. 



Habitat. — Polypi in the nose of man : Bengal, Calcutta ; 

 Madras, Madras ; Ceylon. 



305. Rhinosporidium sp. 



flSTot identified, Vasudevan, 1932, pp. 299-302, pi. viii. 



Young trophozoite a spherical encapsuled body, with 

 a distinct nucleus and nucleolus. The capsule is hyaline, 

 doubly-contoured, and l-6ju, in thickness. The cjiioplasm is 

 vacuolated and in some trophozoites contains thin protoplasmic 

 granules. Nucleus central, occasionally peripheral and mar- 

 ginal, 4'8jLt in diameter, with nucleolus 1-6 /x in diameter. In 

 later stages the organism is larger and protoplasmic strands and 

 granules are pronounced. One of them was somewhat pear- 

 shaped, probably due to an obhque section. 



Dimensions. — The organism measured 40 ju, by 23^. 



Remarks. — ^The organism somewhat resembles the earlier 

 stages ofi?^.mospon(Zmm in shape, hyaline capsule, protoplasmic 

 strands, and granules, but differs from Rhinosporidium seeberi 

 in that the earhest stage is much larger. The later stages, with 

 spore-bearing sporangia, were not found. The infection was 

 in the skin and not in a mucous membrane. 



Habitat. — Inside walls of abscess cavities, and sometimes 

 in the chronic inflammatory fibrous tissue in man : Ceylon. 



306. Rhinosporidium equi Zschokke. 



Rhinosporidium equi, Zschokke, 1913, pp. 641-50 ; Hartmann, 

 1921, p. 1387 ; Wenyon, 1926, p. 778. 

 '\ Rhinosporidium sp., Rao, 1938, pp. 263-4. 

 \ Rhinosporidium equi, Sahai, 1938, p. 264. 



Probably identical with R. seeberi from man. 



Remarks. — According to Sahai (1938) the first case in an 

 equine was recorded by Krishnamurti Ayyar in Madras in 

 1932. Sahai has recorded another case in a comitry-bred 

 mare in Orissa. The animal had noisy breathing and a blood- 

 stained mucous discharge oozing from one of the nostrils. 

 There was a small cauliflower-Hke growth about one inch 

 long by half an inch thick situated in the anterior part of 

 the nasal chamber, shghtly obstructing the passage. In 

 the connective tissue were found numerous cysts or sporangia 

 in various stages of development, the fully matiu-e ones biu-sting 

 to discharge the spores. Wenyon (1926) doubted if the 

 equine form is distinct from the human form, and Sahai (1938) 

 supports his view. 



Habitat. — Nasal cavities of Equus caballus Linn. : Madras, 

 Madras ; Orissa, Bargarh (Sambalpur).
