Evaluation of trichophyton agars for identification of Trichophyton soudanense

Evaluation of trichophyton agars for identification of Trichophyton soudanense.

Studies of three monoconidial subcultures of each of 10 isolates of Trichophyton soudanense on seven trichophyton agars revealed variations in growth among the subcultures of each isolate and among the isolates themselves on six agars. In contrast, greater consistency and generally good to excellent growth were noted with all isolates on trichophyton agar 1 (basal medium). These results are con...

Isolation of Trichophyton violaceum and Trichophyton soudanense in Baltimore, Maryland.

Tinea capitis is of public health importance because of its transmissibility. Trichophyton violaceum and Trichophyton soudanense, which are common causes of tinea capitis in parts of Africa and West Asia, have only rarely been reported to cause dermatophytoses in the United States. We identified 24 patients with 25 positive cultures for T. violaceum or T. soudanense that were processed in a sin...

Early detection and identification of Trichophyton verrucosum.

A new medium for the early detection and identification of Trichophyton verrucosum has been formulated. The key ingredients of the medium are 4% casein and 0.5% yeast extract. T. verrucosum is recognized by its early hydrolysis of casein and very slow growth. Microconidia were produced by 19 out of 35 isolates (54%), and macroconidia were produced by 8 out of 35 isolates (23%). All isolates for...
