Bacteria of the Streptococcus anginosus group (SAG) have recently been recognized as contributors of bronchopulmonary disease in cystic fibrosis (CF). Routine detection and quantification are limited by current CF microbiology protocols. The development of the CHROMagar™ StrepB chromogenic medium modified by the addition of plasma, nalidixic acid, colistin and sulfadiazine to make it selective for SAG bacteria is described. This medium could be used as a diagnostic tool to detect SAG in respiratory samples from patients suffering from chronic lung disease.
咽峡炎链球菌群（SAG）细菌最近被认为是囊性纤维化（CF）患者支气管肺部疾病的致病因素。目前CF微生物学检测方案限制了SAG细菌的常规检测和定量分析。本文介绍了通过添加血浆、萘啶酸、黏菌素和磺胺嘧啶对CHROMagar™ StrepB显色培养基进行改良，使其对SAG细菌具有选择性。该培养基可用作诊断工具，以检测慢性肺病患者呼吸道样本中的SAG细菌。
