title: Occurrence of Trichophyton megninii in Ontario. Identification with a simple cultural procedure.
abstract: Five strains of Trichophyton migninii were isolated in Toronto from four people. One patient probably was infected in Toronto since he had not visited the European endemic area. These were the first isolates made in Ontario; a requirement for L-histidine was determined. A cultural differentiation of T. migninii and T. rubrum is described. Attention is directed to the similarity of the metabolism for dextrose in Bromocresol purple milk dextrose agar by T. megninii and T. mentagrophytes which differs from T. rubrum.
