The role of zinc cluster protein transcription factors in regulating antifungal resistance in pathogenic yeast «Candida glabrata»

Candida glabrata is an emerging opportunistic fungal pathogen which is the overall second leading contributor after Candida albicans in all candidiasis infections, especially in patients with compromised immune systems, such as patients who suffer from AIDS or have received organ transplants.
