[Identification of clinically isolated fungi and their culture collection system in Japan].

Due to the serious financial condition of the health care insurance system in Japan, many clinical microbiology laboratories in hospitals have been forced to close or downsize, and therefore identification of pathogenic fungi isolated in these hospitals has become more and more difficult. This problem becomes even more serious when rare but clinically important fungi are the causative agents. For the smooth and accurate identification of the fungi, formation of a collaborative network among hospital laboratories, private clinical laboratory test centers and university research laboratories is now required. In contrast, the culture collection system of pathogenic fungi for deposit and distribution has been significantly improved in the past few years largely due to the support of the National BioResource Program. The most important part of this kind of system is its longevity, and further improvement is warranted to keep the system viable even after the end of the Program.
