摘要

开发了一种胆汁培养基，用于快速推定鉴定溶血性B组链球菌。131株B群链球菌临床分离株中，125株(95.4%)在培养6 h内产生阳性反应。134株A、C、F、G型乙型溶血性链球菌临床分离株均未发现假阳性反应。胆汁液、快速马来酸水解和改性LAL-1培养基的敏感性分别为95.4、98.5和93.1%。三种培养基均显示100%特异性。因此，胆汁培养基可作为B群链球菌快速推定鉴定的额外培养基。

Bile medium for rapid presumptive identification of group B streptococci.

A bile medium was developed for rapid presumptive identification of beta hemolytic group B streptococci. Of 131 clinical isolates of group B streptococci, 125 (95.4%) yielded positive reaction within 6 h incubation. No false positive reaction was found in 134 clinical isolates of groups A, C, F, and G beta-hemolytic streptococci. The sensitivities of the bile medium, rapid hippurate hydrolysis and modified LAL-1 medium were 95.4, 98.5 and 93.1%, respectively. All three media showed 100% specificity. Therefore, the bile medium provides as an additional medium for rapid presumptive identification of group B streptococci.
