2123例男性泌尿生殖道标本的病原学分析

目的了解男性泌尿生殖道感染的病原学分布，为男性泌尿生殖道感染的预防和治疗提供可靠依据。方法对2123例男性泌尿生殖道标本的微生物学检验进行回顾性分析。结果2123例男性泌尿生殖道标本中共检出病原菌1082株，检出率为50．96％，其中解脲支原体检出率最高，为24．30％；所有送检标本中，尿道拭子标本的病原菌检出率最高，为60．09％，混合感染率为12．74％；精液标本中无乳链球菌检出率明显高于前列腺液（P〈0．05）。结论解脲支原体是男性泌尿生殖道感染的主要病原菌：男性泌尿道标本的病原学检查以尿道拭子为宜；男性不孕是否与无乳链球菌的感染有关还有待进一步研究。

Pathogenic Analysis of Male Genitourinary Specimens

Objective To examine the distribution of pathogens responsible for male genitourinary infection and to provide evidences for the prevention and treatment of male urogenital infection. Method Samples from 2123 male subjects with genitourinary infections were retrospectively analyzed with microbiological tests. Result A total of 1082 pathogens were isolated and the detection rate was 50.96%. Ureaplasma urealyticum was the major isolated species and the detection rate was 24.30%. The percentage of urogenital samples showing bacterial infection and mixed type infection was 60.09% and 12.74%,respectively. The detection rate of Streptococcus agalactiae from semen was significantly higher than the prostatic secretion （P〈0.05）. Conclusion Ureaplasma urealyticum was the major pathogen responsible for male genitourinary infection. Urethral swab was the most appropriate method to collect male urogenital tract specimens for pathogens inspection. Further studies are required to determine the correlation between Streptococcus agalactiae infection and male infertility.
