The identification and comparative study of species of the ringworm fungi depend largely on the gross cultural characteristics, which may vary greatly according to the mediums used.

With Sabouraud's international proof mediums as standards for comparison, a study was made of other peptones, maltose and dextrose with a view to developing a standard American medium composed of easily procurable and medium priced ingredients.

SUGARS

The observations on maltose and dextrose may be summed up as follows: 1. Chemical examination of the Sabouraud crude maltose and dextrose showed them both to be crude dextrose (glucose), not differing materially in composition from crude American dextrose of low specific rotary power, as manufactured by the complete hydrolysis of cornstarch. 2. Chemically pure maltose as a substitute in Sabouraud's proof mediums affords poor growth and unsatisfactory culture comparisons, whereas the substitution of chemically pure dextrose affords satisfactory growths and comparisons. Substitutes of crude maltose . . . [Full Text PDF of this Article]
