Abstract:
The food poisoning caused by Bacillus cereus occurs in Kunming or Yunnan Province sometimes.The aim of our survey is to prevent and control this kind of food poi- soning in the future.The result shows that the positive rate is 19.20% and the degree of contamination differs in the different kinds of food,the dairy products being contaminated most seriously of all.The bacteria in the contaminated food number mostly 10~2～10~4 per gram,Though it is not very high,the presence of Bacillus cereus is so wide that we showld pay much attention to it. Abut 97.65% of Bacillus cereus can be biologically classified and the most com- mon types are 2,8 and 10.About 92.98% of Bacillus cereus can be classified according to the serological type,and type 3 is the most predominant one and type 1 the second.In the dairy products,biological types 2 and 8 make up 54.55% and serological type 1 36.36%. The bacteria isolated from the food are highly sensitive to erythromycin,chlor- amphenicol,gcntamycin,streptomycin and kanamycin.
