Morphological Classification of Fungal Infections (Yeasts, Mold, Dimorphic)

Abstract

Morphological examination of a fungal isolate is a fundamental tool in understanding medical mycology. Despite advanced molecular techniques, macroscopic and microscopic observation for the classic morphological features continue to be the basis for phenotypic identification of a fungal isolate in the clinical laboratory. Mycologists are interested in the structure of the reproductive bodies and the manner in which they are produced as these features constitute the most important basis for classification and taxonomy of the fungi. Morphogenesis is an important virulence factor related to pathogenic fungi. The diverse morphological changes allow for the fungi to evade, manipulate and overcome host immune defences. Also, the asexual forms represent major methods for the maintenance and dissemination of the species.
