Vaginal Isolates of Candida glabrata are Uniquely Susceptible to Ionophoric Killer Toxins Produced by Saccharomyces cerevisiae.

Compared to other species of Candida yeasts, the growth of Candida glabrata was inhibited by many different strains of Saccharomyces killer yeasts. The ionophoric K1 and K2 killer toxins were broadly inhibitory to all clinical isolates of C. glabrata from patients with recurrent vulvovaginal candidiasis, despite high levels of resistance to clinically relevant antifungal therapeutics.
