Abstract
In a previous paper observations were made on the growth of certain pathogenic fungi on a medium containing alcoholic nigrosine and one containing litmus. 1 In the present paper a like medium (peptone 4%, dextrose 1%, agar 1 1/2%) containing 2% Eosin Y and one containing 2% Eosin B∗ were used.
The following pathogenic fungi and 2 saprophytes, Lichtheimia sp. and Scopulariopsis brevicaulis were observed: Achorion schoenleinii, Acladium castellani, Candida candida, Endodermophyton tropicale, Endomyces capsulatus, Endomyces dermatitidus, Epidermophyton inguinale, Glenospora gammeli, Geotrichum bachmann, Indiella americana, Monosporum apiospermum, Microsporon audouini, Monilia albicans, Oöspora humi, Trichophyton crateriforme, Trichophyton granulosum, Trichophyton interdigitale, Trichophyton japonicum, Willia anomala. Observations were made over 30 days. The tubes were kept at room temperature.
Growth occurred within 4 days in all tubes of the control media and in the dye tubes with the exception of Achorion schoenleinii, Endodermophyton tropicale—Eosin B, Glenospora gammeli, Microsporon audouini—Eosin Y where it occurred in 6 days, Endodermophyton tropicale—Eosin Y, Microsporon audouini—Eosin B, where it occurred within 11 days and Trichophyton crateriforme, Trichophyton japonicum—Eosin B, where it occurred within 8 days, Growth was as a rule somewhat less marked on the media containing dye but only markedly so in the instance of Trichophyton japonicum.
