Traditional classification methods for fungal pathogens are laborious and insensitive in clinics and laboratories, and tend to have much high demand for technical capability. And duc to the multiplicity, widespread and diversity of fungus, the classification result is usually inconsistent or of diversity. The molecular biology provides new methods for fungus identification. On the base of conventional molecular biology methods, many new techniques identifying clinical pathogenic fungi at the level of DNA have been developed in recent years, which found to be more accurate, rapid, sensitive and specific.
