吉林省15年浅部真菌病菌种分析

An analysis on pathogenic fungi isolated from patients with superficial mycoses in Jilin province during the period of 15 years

目的:了解15年1986年～2001年吉林省浅部真菌病的致病菌及菌种变迁情况,指导临床预防治疗。方法:用沙堡琼脂培养基分离培养15年吉林省浅部真菌病的致病菌,并动态分析各年代菌种分离结果。结果:共分离出8种2763株致病菌,其中红色毛癣菌居首位,须癣毛癣菌居第2位,犬小孢子菌居第3位。在头癣病原菌中,犬小孢子菌由80年代的84.3%逐渐减少,至90年代后期仅占9.6%。而红色毛癣菌则逐年增高。在其他各病种中,红色毛癣菌及絮状表皮癣菌逐年增高,犬小孢子菌则逐年减少。结论:15年吉林省浅部真菌病致病菌种有明显变迁,尤其犬小孢子菌随年代明显减少为显著特征。

Objective:To dynamically analyze the changes of pathogenic fungi in Jilin province in the period1986～2001.Meth ods:Pathogenic fungi of superficial mycoses were isolated,identified and dynamically analyzed.Results:Two thou-sand,seven hundred and sixty three pathogenic fungi in8species were isolated during the period of15years.T.rubrum was the most com mon pathogenic fun gus,and then came T.mentagrophytes and M.canis.The dynamical analysis showed that there were ob vious changes of pathogenic fungi,especially for tinea capitis.Such as the infections of M.canis decreased from84%in1980s to9.6%in late1990s;however,that of T.rubrum increased gradually during this period.With regard to oth er su perficial mycoses,the isolating rate of T.rubrum and E.floccosum increased with years,while that of M.Canis decreased with years.Conclusion:These re sults indi cated that the changes of pathogenic fungi were significant,especially for the infection of M.canis which decreased in the past15years.
