In this study, two PCR-based methods (MSP-PCR and PCR-MP) were compared for their abilities to identify intraspecies variations of 23 isolates of Trichophyton rubrum, 78 isolates of Trichophyton interdigitale and 22 isolates of Microsporum canis, obtained mainly from patients in Lódź city. The results allowed to distinguish four types (containing two subtypes) characteristic for T. interdigitale and three types characteristic for T. rubrum using PCR-MP method. Analysis conducted using MSP-PCR with (GACA)4 primer revealed four types for T. rubrum and three types (containing one subtype) for T. interdigitale and with (GTG), primer showed two types (containing one subtype) for T. rubrum and six types (containing one subtype) for T. interdigitale. No differentiation was observed for the M. canis isolates with either method.
