The activity of Wa1F1-KT was tested against the reference C. albicans strain SC5314, two wild-type C. albicans clinical isolates (DSY544 and DSY347) , two C. albicans mutant strains resistant to fluconazole (DSY775, derived from DSY544, and DSY289, derived from DSY347) , two wild-type C. glabrata clinical isolates susceptible (DSY562) and resistant (DSY565) to fluconazole , and four C. glabrata fluconazole-resistant strains derived from DSY562 by mutations in the gene CgPDR1 (SFY93, SFY105, SFY115, SFY116) . The reference strain C. lusitaniae NEQAS 6208, known to be susceptible to the activity of Wa1F1-KT , was also used as a positive control for KT activity.
