摘　　要：目的了解石家庄市肉毒梭菌在土壤中的分布情况,为预防、诊断、治疗肉毒梭菌食物中毒提供科学依据。方法按照地貌,均匀抽取8个县(市、区),采集不同类型的土壤检测肉毒梭菌污染情况。结果采集土壤样品244份,肉毒梭菌检出13份,检出率为5.3%,其中,10份为B型肉毒毒素,3份为A型肉毒毒素。发生过肉毒中毒县(市、区)肉毒梭菌检出率高于未发生过县(市、区)(P<0.05)。山区与平原肉毒梭菌检出率差异无统计学意义(P>0.05)。结论石家庄市土壤中肉毒梭菌污染较以前严重,并且存在A型肉毒毒素。Objective To explore the contamination of Clostridium botulinum in the soil of Shijiazhuang,and to provide a scientific basis for preventing,diagnosing and treating food-borne botulism. Methods According to landform,8 counties（cities or districts） were chosen evenly to collect different types of soil for testing Clostridium botulinum. Results A total of 244 samples were tested,and Clostridium botulinum was found in 13 samples（5.3%）.Among the 13 samples,Clostridium botulinum type B was detected in 10 samples,and Clostridium botulinum type A was found in 3 ones.The contamination rates in the counties（cities or districts） with the incidence of food-borne botulism were higher than those of the counties（cities or districts） without the incidence of food-borne botulism（P〈0.05）.No statistically significant difference was found in the detection rate of Clostridium botulinum between the mountain areas and the plain areas（P〉0.05）. Conclusions The prevalence of Clostridium botulinum in Shijiazhuang City is higher than before,and Clostridium botulinum type A exists.
