Standardized molecular typing.
Molecular typing methods are useful tools in molecular mycology. The results of these biotyping procedures may help to identify pathogenic strains in order to detect sources of nosocomial infection and for the investigation of epidemiological relationships. With respect to the facultative pathogen, Candida albicans, various methods such as pulse-field gel electrophoresis (PFGE), restriction fragment length polymorphism (RFLP), DNA fingerprinting methods and hybridization with repetitive DNA elements have been described as useful tools in molecular epidemiology. The previously described hybridization method with the Candida albicans specific CARE-2 probe and subsequent rehybridization with a molecular size marker is a standardized reproducible typing method for comparison of results obtained in different laboratories. In a larger epidemiological study conducted at the University Hospital of Würzburg analysing clinical C. albicans isolates, we were able to describe relationships between sequential patient isolates. These findings demonstrate that standardized molecular typing methods are a powerful tool in molecular mycology studies.
