502 MEDICAL MYCOLOGY 



Ectotricliophyton Nakamurae Dodge, n. sp. 



Microsporon sp. Nakamiira, Jap. Jour. Derm. Urol. 31: 1462-1472, 16 figs. 

 [152], 1931. 



Producing- Celsus' kerion on scalp of a boy of 4 years. Japan. Easily 

 inoculable into rabbit and guinea pig. 



Arthrospores, nodular organs, aleurospores, chlamydospores, and multi- 

 locular closterospores present. No spirals, compound thyrses of aleurospores, 

 nor pectinate organs seen. 



Colonies woolly, white, forming- a yellowish brown powdery zone around 

 the central umbo, with a tendency to concentric zones. Pleomorphism in 47 

 days. When the colony is viewed under ultraviolet light, the central portion 

 is reddish brown and the margin an intense violet. 



While Nakamura placed this organism in Microsporum, reporting it closely 

 related to 31. fnlvum, his description of the lesion with mycelium as well as 

 spores within and without the hair, the abundance of pus in the hair follicles, 

 and the elevated lesion all point to a species of Ectotrickophyton. The same 

 conclusion is reached from a study of the morphology of the fungus, where 

 the abundance of nodular organs suggests Ectotrichophyton, althoug'h they 

 have been reported in M. fulvum. 



It seems probable that the organism described by Takahashi, Jap. Jour. 

 Derm. Urol. 28: 542-550, 3 figs., 1928 under the name Trichophyton farinulentum 

 should be referred here. Takahashi described his organism as follows : 



Producing tinea capitis profunda in Japan. Pathogenic to guinea pigs. 



Closterospores and terminal and intercalary chlamydospores present, also 

 aleurospores. 



In the incubator, colonies moist, elevated, brown, with deep radial fur- 

 rows and a few pointed coremia in the center. Subcultures white, powdery, 

 with short radial folds and knob in center, later greenish yellow, brownish or 

 red brownish, becoming pleomorphic.

Microsporum (Closteroaleurosporia) fariuulentum Guiart & Grigorakis, 

 Lyon Med. 141 : 377, 1928. 



Producing kerions on both children and adults, much more severe on the 

 scalp than on the glabrous skin. Probably of animal origin but not proved. 

 Inoculable to guinea pig. Occasionally found in France and in Montreal, 

 Canada.
