982 ASCOMYCETES AND BA SIDIOMYCETES 



Gelatine with surface growth whitish; no liquefaction. Said to 

 ferment saccharose, but not maltose or lactose. Its action on 

 glucose is not mentioned. Pathogenic to rats and dogs. 



Saccharomyces samboni Castellani, 1907. 



Cells roundish — 6 to 8 ^ in diameter — easily grown on various 

 media, producing white colonies, which rapidly coalesce. Found 

 by Castellani in Ceylon in a few cases of intertriginous dermatitis 

 of the cruro-scrotal region. A similar or identical organism has 

 been observed by Whitfield in England in a case of the same derma- 

 titis. Ferments glucose, levulose, and maltose. Gelatine is not 

 liquefied. In very old cultures asci present. 



Saccharomyces ellipsoides Rees, 1870. 



Found by Maggiora and Gradenigo in two cases of chronic otitis 

 media. The cells are elliptical, about 6 fj,in maximum diameter; 

 presence of asci. Maggiora and Gradenigo do not consider this 

 fungus to be pathogenic. The yeast is found on ripe grapes, and 

 has been carefully described by Hansen, Asci ellipsoide containing 

 1-4 spores each. The fungus often produces a pellicle in sugar 

 fluid media. Ferments glucose, maltose, and saccharose. 



Saccharomyces hominis Klein and Gordon, 1903. 

 Isolated in some cases of tonsillitis clinically resembling diphtheria. 

 Roundish or oval cells, 5 to 7 ^ in diameter. Pathogenic to guinea-pigs and 

 rabbits. Sugar reactions unknown. 



Saccharomyces anginae Achalme and Troisier, 1895. 

 Found by Achalme and Troisier in a case of tonsillitis showing white 

 patches; in situ cells ovoid, 8-15X5-6 microns. In cultures asci, 4-spored, 

 present. On gelatine, surface growth white. Ferments saccharose, but 

 other reactions not given. 



Saccharomyces balzeri Balzer, Burnier, and Gougerot, 191 1. 



Synonym. — Parendomyces balzeri Balzer, Burnier, and Gougerot, 1911. 



Grows on culture media under the type of oval or roundish yeast-like cells, 

 proliferating by budding. Isolated by Balzer, Burnier, and Gougerot from a 

 gummatous affection. Sugar reactions unknown.

 Saccharomyces blanchardi Guiart. Vuillemin. 

 (After Blanchard, Schwartz, and (After Trosier and Achalme.) 



Binot, from Brumpt.) 



Saccharomyces roseus Maggiora and Gradenigo, 1890. 

 Found by Maggiora and Gradenigo in the Eustachian tube, and considered 

 by them to be non-pathogenic. Cultures of pink colour. Sugar reactions 

 unknown.
