Bacillus cereus food poisoning

Introduction to Bacillus cereus food poisoning It is caused by eating enterotoxin produced by Bacillus cereus. The contaminated food is mainly various foods containing more starch. The main features of vomiting and diarrhea are clinically mild, and the disease course is short, generally not exceeding 12h. . basic knowledge The proportion of the disease: the probability of the population is 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: abdominal pain

The cause of food poisoning by Bacillus cereus

The incubation period varies, such as the intake of live bacteria, about 6 to 14 hours after eating, sudden abdominal pain, diarrhea, watery stool, nausea, vomiting, a small number of patients with fever, such as the intake of bacterial toxins The incubation period is short, 1 ~ 5h, or even as short as tens of minutes, mainly vomiting, accompanied by abdominal pain, a few followed by diarrhea, no obvious fever, mostly self-limiting, lasting 4 ~ 24h recovery.

Anyone who has eaten leftovers or other suspicious foods for 6 to 14 hours with vomiting, abdominal pain or diarrhea should be suspected of Bacillus cereus food poisoning. The diagnosis depends on the cultivation of Bacillus cereus from suspicious food and patient's stool. The amount of bacteria should reach Each gram of feces contains 105 or more, which has diagnostic significance. The bacteria should be identified as serotype and biotype, and the enterotoxin test should be carried out to determine the virulence.

Bacillus cereus food poisoning prevention

Bacillus cereus is widely distributed. Prevention is mainly to prevent food contamination, not to eat spoiled leftovers, leftovers, strict hygienic requirements for salads, food should be fully heated, should not be placed at room temperature for too long, if not eaten immediately, should Cool as soon as possible, keep at low temperature, and warm before eating.

Examination of food poisoning by Bacillus cereus

Bacillus cereus is cultured in the feces.

An enterotoxin test should be performed to determine if there is virulence.

Clinical should be differentiated from general enteritis.
