一般說明

胆盐是一种有机钠盐混合物，包含任意胆汁酸与甘氨酸或牛磺酸的结合物。胆盐由四种不同的胆汁酸组成：胆酸、脱氧胆酸、鹅脱氧胆酸和石胆酸。胆盐是在受控条件下由纯化的新鲜胆汁提取出来，可加入细菌培养基作为一种选择性抑制剂抑制革兰氏阳性菌和诱导孢子萌发。还抑制萌发孢子生长，但不干扰肠杆菌生长。

應用

胆盐混合物适合用于加入多种培养基，如麦康凯琼脂、SS琼脂和结晶紫中性红胆盐琼脂。它通过抑制革兰氏阳性菌提高培养基对肠杆菌的选择性。可作为培养基选择剂用于选择性培养肠道细菌，包括大肠杆菌、其他粪便大肠菌群和粪便链球菌。也作为培养基选择剂用于检测小肠结肠炎耶尔森菌、嗜水气单胞菌和弧菌属。

準備報告

从纯化的新鲜胆汁中提取。

Colonization of the gastrointestinal tract by enterohaemorrhagic Escherichia coli (EHEC) is critically dependent on its ability to sense and respond to various microenvironments within the host. EHEC exposure to physiologically relevant levels of bile salts upregulates the two-component system, pmrAB

During passage through the human gastrointestinal tract, enterohemorrhagic Escherichia coli (EHEC) is exposed to membrane-damaging bile in the small intestine. We previously reported that EHEC treatment with a physiological bile salt mixture upregulates basRS, encoding a two-component system, and arnBCADTEF
