摘要
嗜水气单胞菌在自然界广泛分布,是一种典型的人-畜-鱼共患病病原菌,人类可因致病性嗜水气单胞菌感染而发生腹泻、食物中毒、继发感染。由于嗜水气单胞菌菌落易与肠杆菌科细菌特别是大肠杆菌混淆,氧化酶试验阳性是其特征,常规检测非常必要。蛋白酶阳性可确定该菌为致病性嗜水气单胞菌,另外还可用PCR检测Aer基因来区别致病性嗜水气单胞菌和非致病性嗜水气单胞菌。目前,国外已将嗜水气单胞菌纳入腹泻病原菌的检测范围,是食品卫生检测的对象。因此,建议在食品、饮用水检测指标中增加嗜水气单胞菌作为细菌学指标,并将其纳入食物中毒诊断标准中。
Aeromonas hydrophila （AH）, which distributes extensively in the nature, is a kind of typical human-domestic animal-fish＇s pathogens. The human can suffer from diarrhea, food poisoning, and secondary infection because of pathogenic AH. Though AH colony is from euterobac terlcaeae especially Escherichia coli, it＇s difficult to distinguish its characteristics with positive oxiduse. It is very essentive to make the routine measurement. The positive protease can confirm this fungus and Aer gene with PCR can be measured to distinguish pathogenic and at present AH is included in the test scope for the pathogen of diarrhea. And it is one of the target for food hygiene in the foreign countries. So it is purposed to add AH as bacteriological index in food and drinking water, and is included in the diagnostic standard for food poisoning.
