Abstract
A study was made of the growth of pathogenic fungi on hair and scalp products before puberty, as collected and after extraction with ether in a Soxhlet for 24 hours. 1 A similar study of hair and scalp products of men and women is here reported. Care was taken that this hair was clean, untreated and undyed. The hair of numerous individuals of different ages was mixed. About 6 cc. of hair was placed in test tubes, covered with distilled water, the tubes plugged with cotton and autoclaved.
The following pathogenic fungi and 2 non-pathogenic saprophytes Lichthemia sp. and Scopulariopsis brevicaulis were studied: Achorion schoenleinii, Acladium castellani, Candida candida, Endodermophyton tropicale, Endomyces capsulatus, Endomyces dermatitidus, Epidermophyton cruris, Epidermophyton inguinale, Glenospora gammeli, Geotrichum bachmann, Indiella americana, Microsporon audouini, Microsporon felincum, Microsporon gypseum, Monosporum apiospermum, Monilia albicans, Oöspora humi, Sporotrichum schenkii, Trichophyton crateriforme, Trichophyton granulosum, Trichophyton gypseum asteroides, Trichophyton gypseum lacticolor, Trichophyton interdigitale, Trichophyton japonicum, Trichophyton niveum, Trichophyton sulfureum, Willia anomaia.
In reporting results W is used to designate women's hair, M men's, EW extracted women's hair, EM extracted men's. All organisms studied showed growth on our stock 4% peptone, 1% dextrose, 11/2% agar medium in 3 days. Growth was at room temperature in diffuse light.
Acladium castellani, Candida candida, Geotrichum bachmann, Lichtheimia sp., Microsporon felineum, Microsporon gypseum, Monilia albicans, Oöspora humi, Sporotrichum schenkii, Trichophyton granulosuni, Trichophyton gypseum asteroides, Trichophyton gypseum lacticolor, Trichophyton interdigitale, Trichophyton japonicum, Trichophyton niveum, Willia anomala showed growth on all hair media in 3 days.
