目的 :为了加强饮食食品从业人员的卫生管理 ,了解本辖区沙门氏菌菌型变迁的情况 ,防止因沙门氏菌引起的食物中毒的发生。方法 :采用肛拭培养法分别对 1997～ 1999年本辖区食品从业人员进行健康带菌检查 ,并对分离出的沙门氏菌进行血清学分群、分型以及带菌与年龄之间关系分析。结果 :1997～ 1999年三年沙门氏菌的带菌率分别为 0 .49%、1.2 1%、 0 .79%。其中 1997年菌株分 7个血清群 17个血清型。 1998年菌株分为 8个血清群 2 5个血清型 ,1999年菌株分为9个血清群 31个血清型 ,并且这三年均以德尔俾沙门氏菌菌型流行为主。带菌率较高的年龄组分布在 2 0～ 2 9岁之间。结论 :本辖区食品从业人员所携带的沙门氏菌血清菌群 ,菌型逐年增多
Objective: In order to strengthen the health management of food and beverage practitioners, understand the change of Salmonella bacteria in this area and prevent the food poisoning caused by Salmonella. Methods: The anal swab culture method was used to carry out the health check of food workers in the area from 1997 to 1999 respectively. And the serological grouping, typing and the relationship between the bacteria and the age of Salmonella isolates were analyzed. Results: The incidence of Salmonella in 1997 ~ 1999 was 0.49%, 1.2 1%, 0.79% respectively. In 1997, the strains were divided into seven serogroups and 17 serotypes. In 1998, the strains were divided into 25 serogroups of serogroups of serogroups. In 1999, the isolates were divided into 9 serogroups of 31 serotypes, and all of them were predominantly delphi salmonella in these three years. Age groups with higher incidence of bacteria distribution in 20 ~ 29 years old. Conclusions: Salmonella serogroups carried by food practitioners in this area have been increasing year by year
