An outbreak of food poisoning due to enterohemorrhagic Escherichia coli O157 in Niigata, Japan.

Multiple-locus variable-number tandem repeat analysis of enterohemorrhagic Escherichia coli O157 in outbreak of food poisoning caused by formed beef chunk steaks.

Characterization of enterohemorrhagic Escherichia coli O111 and O157 strains isolated from outbreak patients in Japan.

In April and May 2011, there was a serious food-poisoning outbreak in Japan caused by enterohemorrhagic Escherichia coli (EHEC) strains O111:H8 and O157:H7 from raw beef dishes at branches of a barbecue restaurant. This outbreak involved 181 infected patients, including 34 hemolytic-uremic syndrome (HUS) cases (19%). Among the 34 HUS patients, 21 developed acute encephalopathy (AE) and 5 died. ...

Serodiagnosis using microagglutination assay during the food-poisoning outbreak in Japan caused by consumption of raw beef contaminated with enterohemorrhagic Escherichia coli O111 and O157.

A microagglutination (MA) assay to identify antibodies to Escherichia coli O111 and O157 was conducted in sera collected from 60 patients during a food-poisoning outbreak affecting 181 patients in Japan which was caused by the consumption of contaminated raw beef. Enterohemorrhagic E. coli (EHEC) O111:H8 and/or O157:H7 was isolated from the stools of some of the patients, but the total rate of ...

Enhancement of enterohemorrhagic Escherichia coli O157:H7 stress tolerance via pre-heating.

Enterohemorrhagic Escherichia coli O157:H7 infection causes several hundred cases of food poisoning every year in Japan. In severe cases, this type of food poisoning can be fatal. In the present study, we examined the induction of HSP70 in E. coli O157:H7 cells at various temperatures and the thermotolerance of E. coli O157:H7 cells alone and in contaminated food following pre-heating. We evalu...
