Matings among three teleomorphs of Trichophyton mentagrophytes.
Three genetically hybrid F1 progenies produced between a clinical isolate of Arthroderma simii (KMU4810) and a tester strain of A. vanbreuseghemii (RV27961) were crossed with two tester strains of A. vanbreuseghemii (RV27961 and RV27960) and a tester strain of A. benhamiae (RV30001), respectively. Three crossings yielded hybrid second progenies. Another interspecies crossing between A. simii (KMU4810) and a tester strain of A. benhamiae (RV26680) yielded one hybrid F1 progeny (Asb57). The second crossings of F1 progeny (Asb57) with A. vanbreuseghemii (RV27961) and A. benhamiae (RV30001) yielded many hybrid second progenies. Some hybrid second progenies produced between F1 progeny and A. vanbreuseghemii were confirmed to have genes from three species. The gene exchangeability among three Arthroderma species was shown and the meaning of these events discussed.
