目的:了解重庆地区浅部真菌病病原菌菌种分布特点。方法:对2005年1月—2006年12月收集的2135例浅部真菌病临床标本进行直接镜检、培养及菌种鉴定。结果:镜检阳性率为66.5%,培养阳性率为55.7%。菌种分布主要为:红色毛癣菌872株(68.2%),犬小孢子菌50株(3.9%),须癣毛癣菌48株(3.8%),念珠菌及酵母样菌173株(13.5%),曲霉26株(2.0%),青霉11株(0.9%)。结论:①重庆地区浅部真菌感染中,皮肤癣菌仍占主导地位。男性皮肤癣菌的镜检及培养阳性率均高于女性,冬季癣菌的检出率低于春、夏、秋三季。②红色毛癣菌为优势致病菌,但其在15岁以下年龄组患者中的感染率明显低于其他年龄组。
Objective: To understand the distribution characteristics of pathogenic fungi strains in shallow area in Chongqing. Methods: 2135 cases of superficial mycosis clinical samples collected from January 2005 to December 2006 were directly examined by microscopy, culture and strain identification. Results: The positive rate of microscopy was 66.5% and the positive rate of culture was 55.7%. The distribution of bacteria mainly included 872 strains of Trichophyton rubrum (68.2%), 50 strains of Microsporum canis (3.9%), 48 strains of Trichophyton mentagrophytes (3.8%), Candida species and 173 strains of yeast-like bacteria 26% (2.0%) of Aspergillus and 11 strains of Penicillium (0.9%). Conclusion: (1) Dermatophytes still dominate in superficial fungal infections in Chongqing. The positive rate of microscopic examination and culture of dermatophytes of male was higher than that of female, and the detection rate of ringworm in winter was lower than that of spring, summer and autumn. ② Trichophyton rubrum is the dominant pathogenic bacteria, but its infection rate in patients under 15 years of age was significantly lower than other age groups.
