MEDICAL MYCOLOGY 



Debaryomyces Bumieri Ota, Ann. Parasitol. Hum. Comp. 2: 35-37, 1924. 



This organism was isolated from epidermomycosis of eczematous aspect. 



Grown on malt agar, at 25° C. for one day, it shows spherical or ovoid 

 cells, 4-5/x in diameter or 8-10 x d/x, occasionally up to 15/a long, solitary or in 

 twos, occasionally in chains. There are large vacuoles and fat globules. The 

 cell wall is very thin. After 7 days, cells solitary or in twos, membrane 

 thicker. On carrot, cells may be solitary or in groups, but not in chains, walls 

 thick, 1-12/* in diameter. On malt extract, cells often in chains. Gorodkova 

 agar shows sporulation on the third day. Asci spherical, ovoid, or polyhedral, 

 4-7/i,. Ascospores spherical or ellipsoid, 2-4/a, verrucose, uniguttulate. 



On malt agar, colony chalky white, smooth, even edges. In malt extract 

 a whitish deposit appears in 24 hours, and on the tenth day a ring which 

 thickens and yellows on the fortieth day. Fermentation not reported.
