[New fungal classification and their applications in medicine].
Fungi are gaining importance with the increased incidence of invasive, often fatal mycoses, in immunocompromised patients. In addition, the increased number of emerging opportunistic pathogens has prompted interest in studies pertaining to fungal classification. The traditional methods of identification and classification of these microorganisms are based on the morphology of the sexual and asexual reproductive structures. Recently, this system of classification has been shown incongruent with approaches that better establish phylogenetic relationships among these organisms. Novel aspects of fungal reclassification are described as follows: 1) the position of fungi in the historical classification systems, 2) the recognition of their polyphyly, based on comparative studies of nucleic acid sequences and on analysis of descent lines and, 3) the contribution of molecular phylogeny to medical mycology, including identification of mycotic agents, their molecular epidemiology, prevention of infection and methods of diagnosis.
