[Survey on the medical mycology processes to the members of the French Society for Medical Mycology].
OBJECTIVE
The objective of the survey was to describe the practices of clinical laboratories in terms of cultures in medical mycology. We have implemented this project within the members of the French Society for Medical Mycology (SFMM) to evaluate the analytical processes of the mycological examination in our laboratories. This preliminary study would help to suggest the future French guidelines.


METHODS
A questionnaire regarding the processing of mycology analysis was sent to the 227 members of the SFMM in 2009. The data involved 21 types of samples, direct microscopic examination with or without colouring and the reagents, the number of culture media, the types of media (Sabouraud, Sabouraud antibiotic, Sabouraud cycloheximide and chromogenic medium), temperature and duration of the incubation (days) and the existence of a first result before the end of the incubation period. The analytical processes were compared to an accredited laboratory according to EN ISO 15189.


RESULTS
A great heterogeneity was observed in the 36 forms from 27 (75%) laboratories belonging to university hospitals among the 38 existing in France. As for deep samples, two microscopic exams were performed, only one was usually done. A more sensitive technique was preferred to the wet-mount for some samples. Routine samples are often inoculated on a chromogenic media. For deep samples two medium are inoculated (chromogenic media, Sabouraud and antibiotics). If the temperature of incubation is unique, 30°C was chosen. A temperature of 37°C was preferred for samples where Candida spp. is selected. When there are two temperatures of incubation, 27°C and 37°C were preferred.


CONCLUSIONS
Each biologist can compare his proceedings to the other laboratories and to a laboratory already accredited. The question is to find the best strategies for each medical mycology specimen. They will aid the process of accreditation according to EN ISO 15189, which now applies in all laboratories in Europe.
