Abstract

Unlabelled: The aim of this study was to determine the antibiotic resistance of Streptococcus agalactiae strains isolated from urocultures in order to obtain new data regarding circulating phenotypes in Urology Department.

Methods: For identifications of Streptococcus agalactiae strains we used Pastorex Strep (BioRad). The sensitivity of isolated germs to antimicrobials was tested using standardised Kirby-Bauer technique.

Results: We isolated 21 Streptococcus agalactiae strains from 1871 urocultures. Analyzing the extended antibiograms we categorized these germs according with their resistance phenotypes and we remarked a high percentage of wild type phenotype Streptococcus agalactiae strains (80.95%).

Conclusions: Streptococcus agalactiae strains are more rarely isolated from hospital acquired urinary tract infections, that's way we can explain the low resistance of these strains.

[从尿培养物中分离的无乳链球菌的表型特征]。

未标记:本研究的目的是确定从尿培养物中分离的无乳链球菌菌株的抗生素耐药性，以便获得泌尿科循环表型的新数据。方法:采用Pastorex Strep (BioRad)对无乳链球菌进行鉴定。采用标准化的Kirby-Bauer技术检测分离细菌对抗菌素的敏感性。结果:从1871株尿路培养物中分离到21株无乳链球菌。我们根据耐药表型对这些细菌进行了抗生素谱分析，发现野生型无乳链球菌的比例很高(80.95%)。结论:无乳链球菌在医院获得性尿路感染中较少见，这可以解释无乳链球菌耐药性较低的原因。
