BACKGROUND
Group B Streptococcus (GBS) is an important pathogen that causes serious infections in newborns. Pregnant screening and intrapartum antibiotic prophylaxis are actually the strategies to prevent GBS disease in neonates because vaccination is under investigation.
MATERIALS AND METHODS
Simultaneously, 156 isolates of GBS and 156 isolates other than GBS covering 17 different species, were tested to evaluate the selectivity of a new chromogenic medium to screen GBS.
RESULTS
The new new chromogenic medium showed an excellent performance, exhibiting a very high level of inclusivity (100%) and exclusivity (96.1%).
背景
B族链球菌（GBS）是导致新生儿严重感染的重要病原体。由于疫苗接种尚在研究中，孕期筛查和产时抗生素预防实际上是预防新生儿GBS疾病的策略。
材料与方法
同时，对156株GBS分离株和156株非GBS分离株（涵盖17个不同物种）进行检测，以评估一种新型显色培养基筛查GBS的选择性。
结果
新型显色培养基表现出色，具有很高的包容性（100%）和排他性（96.1%）。
