Mycosis in Jillin Province, China

Abstract

In the past 15 years, from 1986 to 2000, 2,763 cases of superficial mycoses had been diagnosed and treated in Jillin Province. Other mycoses included 1,450 cases of tinea versicolor, 497 cases of candidiasis, 142 cases of sporotrichosis, 1 case of chromomycosis, and 47 cases of aspergillosis. Among the 2,763 cases of superficial mycoses, 762 cases were tinea cruris, 246 cases were tinea manus, 661 cases were tinea pedis, and 156 cases were onychomycosis. From the region, there was a high incidence of sporotrichosis in the middle and the west part of our province, and there was rather low incidence of it in the eastern mountain areas. We separated Sporothrix schenckii from the natural environment. Sporothrix schenckii was separated from the plants and the soil in both the region of high incidence and low incidence. Therefore, the reason why there's a low incidence in the eastern mountain areas is still unknown. Pathogenic fungi were separated, and we found 2,038 strains of T. rubrum, which came first in the pathogenic fungi of dermatophytoses. Coming next were T. mentagiophytes, M. canis, E. floccosum, M. gypseum and T. violaseum. Sporothrix schenckii was separated from all of the 142 cases of sporotrichosis. Candida albicans A, Candida albicans B, Candida tropicalis and Candida parapsilosis were separated from candidiasis; Exophiala jeanselmei was separated chromomycosis; A. fumigatus, A. niger, and A. favus were separated from aspergillosis. The problem we should pay attention to is; In the 1980's, M. canis came third in the pathogenic fungi of dermatophytoses, first in that of tinea capitis, which took 84.2% in the pathogenic fungi of tinea capitis. But from the beginning of 1990's, the number had declined. By the end of 1990's, M. canis just took 9.6 percent in the pathogenic fungi of tinea capitis. And the separation rate of M. canis from cat had obviously declined. Whether it's getting to vanish like M. ferrugineum also needs paying attention to.
