| Abstract: | Lipotropic Yeasts of the Human Skin and their Requirement for Definite Fatty Acids Pityrosporum species can often be isolated from the skin. Their pathogenetic significance is disputed. P. orbiculare and P. ovale differ from each other by their requirement on fatty acids. Oleic acid can be utilized only by P. ovale, whereas myristoleic and palmitoleic acids only by P. ovale, whereas myristoleic and palmitoleic acids only by P. orbiculare. Within the genus P. ovale the individual varieties can be differentiated, for instance, one variety utilizes lauric, myristic, palmitic and stearic acids, another variety only the first three of the said acids and a third one, which utilizes only myristic acid. The different species are sensitive against antimycotica to variable extent. |
