Abstract

Highlights

Hemorrhage E. coil O157:H7 was first reported as a pathogen in 1982 during an outbreak investigation of hemorrhagic colitis [1]
EHEC 0157:H7 caused food poisoning was very rare till in Japan. After this historical large outbreak, EHEC 0157:H7 food poisonings were successively reported each year in our country, suggesting EHEC 0157:H7 agent settled down and contaminated in nationwide area, but we lacked information of O157:H7 behaviours how they were surviving in a natural environment. Under these situations experiments were designed to focus on EHEC 0157:H7 behaviours in water environment to gain fundamental knowledge, comparing to non-pathogenic Escherichia coli
EHEC 0157: H7 was first recognized as a pathogen in 1982 during an outbreak investigation of haemorrhagic colitis EHEC O157 infection can lead to haemolytic uremic syndrome (HUS), characterized by haemolytic anaemia, thrombocytopenia, and renal injury
