Epidemiology and variability of Malassezia spp.

A short review on Malassezia spp., completed with our experience, is made. The main epidemiological characteristics with particular regard to the diffusion in several animal species, the characteristics of skin colonization (in particular of the dog) and the distribution of the different Malassezia spp. in some hosts are discussed. Lastly the main phenotypic and genotypic characteristics, referred to M. pachydermatis especially, were described, showing their high variability and differentiation.
