为探索用简便有效的手段对鼠伤寒沙门菌感染进行调查监测,采用英国学者Duguid的鼠伤寒沙门菌生物学分型方法,应用于医院感染监测、病例追踪、食物中毒调查。结果:从医院感染患儿分离菌侏的主要生物型与医院环境污染、医务人员携带菌株的生物型分布近似;截瘫患者尿中菌株与从其家庭环境和妻子手上分离菌侏生物型别一致;从食物中毒者和剩菜中分离菌株的生物型别与鸭子携带菌株主要生物型别一致。结论:患儿医院感染是由于病房环境污染、医务人员带菌引起;截瘫患者泌尿系感染与家庭环境污染及其妻带菌有关,而非医院感染;食物中毒是由于食用带菌鸭子所致。
In order to explore the simple and effective means of Salmonella typhimurium infection surveillance survey using the British scholar Duguid Salmonella typhimurium genotyping methods used in hospital infection surveillance, case tracing, food poisoning investigation. Results: The biotypes and hospital environment of isolates of juvenile gonorrhea from hospital-infected children were similar, and the biotype distribution of the strains carried by medical workers was similar. The isolates of urine from paraplegic patients were consistent with their isolates from the family environment and their wives The biological patterns of strains isolated from food poisoning and leftovers are consistent with the main biotypes of duck-bearing strains. CONCLUSIONS: The nosocomial infection in children is caused by the environmental pollution in the ward and the carriage by medical staff. The urinary tract infection in paraplegic patients is related to the pollution of family environment and their wives, not the nosocomial infection. The food poisoning is caused by the ingestion of duck with food.
