| Outline of Final Research Achievements |
We investigated the prevalence situation of highly virulent Cryptococcus gattii infection in Guangzhou City, Guangdong Province, China by collaborating with Department of Respiratory Diseases and Department of Infectious Diseases in the Third Affiliated Hospital of Sun Yat-Sen University. Thirty seven cryptococcosis patients, including thirty five meningitis, one pulmonary cryptococcosis and one cutaneous cryptococcosis, were enrolled, and 38 strains of Cryptococcus spp. were isolated. Among them, 36 strains were C. neoformans, all of which were classified in VNI, and 2 strains were C. gattii, including one VGI and one VGII. Thus, in the present study, prevalence of cryptococcosis caused by C. gattii infection was not observed in the south area of China. In addition, we conducted multi-locus sequence typing (MLST) analysis with 7 genetic loci in C. neoformans, which found 88.9% of the strains to be in sequence type 5. These data are similar to the reports in Japan and South Korea.
