A histidine-containing agar medium has been devised for quantitative detection of histamine-producing bacteria that are alleged to be associated with scombroid fish poisoning outbreaks. The responsible bacteria produce a marked pH change in the agar, with attendant color change of pH indicator adjacent to the colonies, thus facilitating their recognition. Proteus morganii and Klebsiella pneumoniae were the two most common histidine-decarboxylating species isolated from scombroid fish and mahi mahi.
一种含组氨酸的琼脂培养基已被设计用于定量检测据称与鲭鱼中毒暴发有关的产组胺细菌。相关细菌会使琼脂中的pH值发生显著变化,菌落附近的pH指示剂也会随之变色,从而便于识别这些细菌。摩根氏变形杆菌和肺炎克雷伯菌是从鲭鱼和鲯鳅中分离出的两种最常见的组氨酸脱羧菌。
