Brote epidémico masivo causado por Escherichia coli verotoxigénico (ECVT) 0157 : H7 en Japon.
Traduction en anglais : Epidemiological study of verotoxigenic Escherichia coli O157 : H7 in Japan.
Verotoxigenic Escherichia coli (VTEC) (also denoted enterohaemorrhagic E. coli « EHEC ») O157 : H7 has been recently recognized as a human emerging pathogen associated with haemorrhagic colitis (HC) and haemolytic uraemic syndrome (HUS).
Most outbreaks resulted from the consumption of undercooked minced beef or raw milk.
Thus, the cattle have been identified as a reservoir of VTEC O157 : H7.
In the USA, the number of infections caused by E. coli O157 : H7 is estimated at 10,000-20,000 per year, with 16 outbreaks reported during 1993 and 11 reported during the first six months of 1994.
More than 10,000 Japanese, most of them school children in Sakai, have fallen sick during 1996, the majority of cases occurred in July.
More than 1.000 people were hospitalized and at least 12 patients died.
The 0157 outbreak was centered in Sakai, a suburb of Osaka city.
It has been traced to school lunches prepared by city-run kitchens, but the tainted food carrying the bacteria has not been identified.
Other cases have been linked to a bacterium in raw liver of cow.
Japan government warns against eating raw meat and supermarkets and restaurants are being advised not to carry edible raw meat, a delicacy in Japan.
Obviously, the outbreak has caused a great social alarm and an increasingly decrease of the beef meat consumption.
