Role of pH response in Candida albicans virulence

Mycoses. 2002;45 Suppl 1:16-21. doi: 10.1111/j.1439-0507.2002.tb04540.x.

Abstract

Over 25 years ago it was noted that the pH of the culture medium influenced germ tube formation of Candida albicans, an opportunistic fungal pathogen. This simple observation has been the stimulus for a number of investigations to discern the mechanisms controlling this response and the significance of this response to the biology of C. albicans. Recent studies have demonstrated that a signaling pathway conserved in several fungal species regulates this morphological response to ambient pH and controls the pH-conditional expression of multiple genes. Significantly, C. albicans responds to the pH of the host niche and this response is critical for virulence.
