Abstract
When grown on a range of surfaces in conditions favouring hyphal growth, hyphae of Candida albicans grew in a right-handed helical fashion. This phenomenon was observed with eight strains and with two nutrient media. It is suggested that this is a result of rotation of the hyphal apex as it extends, which on some surfaces results in a helical hyphal wall, but which in a liquid results in a straight hypha. The consequence is that on a surface, a helically growing hypha will be exposed to a more diverse environment than a straight hypha. This phenomenon may have significance in the colonization of tissue by C. albicans.
