Abstract
The food poisoning by the O157 escherichia coli in 1996 did not end in one prefecture and expanded to many other prefectures, in which 9314 patients and 11 dead patients were totally found in that year.
O157 esch e richia coli possesses the same toxin, named verotoxin, as the dysentery bacterium. The verotoxin does not cause only the hemorrhage of intestines, but causes also heavy troubles in kidniys like hemolytic uremic syndrome, because the toxin enters to blood flow from intestine walls and sometimes causes death for infected patients.
The adults often recover only showing diarrhea, w hen they get this disease. Therefore adults like to become healthy germ carriers, and make other people to be infected that disease. The children often become heavy, when they are infected. The adults must be careful for infection to others, when having loose bowels. They must attend to hygiene such as keeping their hands clean, and cooking room, cooking apparatus and food materials also clean.
Treatment must be carefully performed while seeing the state of the patient, administering some antibiotics like new quinoron for 4 to 5 days, because verotoxin is discharged from a broken bacillus in the patients.
The Ministry of Health and Welfare has corresponded the enterohemorrhagic escherichia coli infection syndrome as a specified communicable infectious disease, based on the treatment of the legal communicable disease, but a lot of this infection syndrome found even in 1997,1998.
