目的从临床送检的不同种类标本中,比较念珠菌感染种类的差异,分析不同年份与季节检出念珠菌菌种差异。方法利用包括形态学检查、17种碳源同化、尿素水解和硝酸盐还原试验在内的酵母样真菌微量鉴定方法及Vitek32全自动微生物系统,对451株念珠菌属的真菌作出鉴定。结果来自人体有菌部位标本检出念珠菌90%以上为白色念珠菌,而无菌部位标本检出的念珠菌中白色念珠菌仅占59%,两者存在显著差异;季节及外界环境的差异对念珠菌感染菌株的检出也有影响。结论白色念珠菌是引起感染的主要念珠菌,而其他念珠菌在来自人体无菌部位标本中较为常见。白色念珠菌检出数量各年份间存在一定差异,但季节间无明显差异。
Objective To compare the different types of Candida infection in different types of specimens for clinical examination, and to analyze the difference of Candida species detected in different years and seasons. Methods 451 Candida species fungi were identified by micro-identification of yeast-like fungi including morphological examination, 17 kinds of carbon source assimilation, urea hydrolysis and nitrate reduction test and Vitek32 automatic microbe system. Results Candida albicans was detected in more than 90% of the Candida species in the human body, and Candida albicans only accounted for 59% of the Candida species in the aseptic specimen. There was a significant difference between the two groups in the seasons and in the external environment Detection of candida infection strains also have an impact. Conclusion Candida albicans is the major cause of Candida infection, while Candida albicans is more common in specimens from human sterile sites. The number of Candida albicans detected in each year there are some differences, but no significant differences between seasons.
