摘要
本文对昆明市市售五类食品中蜡样芽胞杆菌的污染状况及其抗药性进行了调查。五类食品中蜡菌的总检出率为19.20%;其中以奶制品的检出率最高,为41.20%;每克食物含菌量多在10~2～10~4之间,污染程度虽不太高,但却较广泛存在。生物学分型以2,8,及10型为主,可分型率为97.65%;血清学分型可分型率为92.98%,以3型最多,1型次之。奶制品中生物2、8型占54.55%,血清1型占36.36%,值得关注。分离菌株对红霉素、氯霉素、庆大霉素、链霉素和卡那霉素均高度敏感。
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.
