临床标本中酵母样真菌的鉴定和分析

Identification and Analysis of Yeast-like Fungus in Clinical Specimens

利用碳源同化试验，辅以假菌丝试验、芽管生成试验、脲酶水解试验等，对临床标本中分离出的酵母样真菌进行了准确鉴定，结果显示：酵母样真菌中白色念珠菌占68．57％，热带念珠菌占14．35％，近平滑念珠菌占5．01％，光滑念珠菌和其它少见的菌种共占12．07％；四者相比有显著性差异（P＜0．05）。提示白色念珠菌仍是临床上最常见的致病性真菌，特别是呼吸道和泌尿生殖道，有较高的检出率；但在胸腹水、血液和其它深部组织中的真菌感染，多是由热带念珠菌和其它少见的真菌引起的。

The Yeast-like fungus in clinical specimens were identified by carbone assimilation test, pseudo-hyphae test, tubing test and urease hydrolysis test. the results showed that 68. 57 percent of the yeast-like fungus were Candida albicans,14. 35 percent of them were Candida tropicalls, 5. 01 percent of them were Candida parapsilosis, 12. 77 percent were Candida glabrata and other rare species. Candida albicans was the most important pathomycete, and it had a high frequency in respiratory tract and uriary-geuital tract infection. In humoral, blood and other internal tissue, it were Candida tropicalls and other rare speces infected more frequently.
