从收集到的３８４１株鼠伤寒沙门氏菌的噬菌体分型结果，分析鼠伤寒沙门氏菌噬菌体型在１４个省市自治区的流行动态。７７７４型（３６１％）在各地广泛分布并常占首位，主要引起感染性腹泻，也引起食物中毒和医院内感染。高峰期在１９８７～１９９１年。１９８７年在福建永安发生的一起最大的７７７４型食物中毒，患者有１１１３人。７７７６型（４０％）主要在新疆流行，高峰期在１９９３年（喀什）。０７７４型（１４４％）是１９８９～１９９１年间在河南各地广泛引起医院内感染的最重要的噬菌体型，此型５５５株培养物在河南分离的便有５０４株（９０８％）。０７７６型（０９％）主要在新疆流行，常与０７７４型的感染同时存在。４７７４型（１０７％）是较为常见的噬菌体型，引起１９８３年新疆阿勒泰的一次大流行，１９８６年上海的一起医院内感染，１９８７～１９９１年辽宁的４起医院内感染和２起食物中毒。４７７６型（１７％）以及与相变异有关的噬菌体型４０００（２６％）和４００２（０９％）亦常与４７７４型同时出现。６７７４型（４５％）见于江西、福建和内蒙古东部的感染性腹泻，６７７６型（１０％）见于湖北的医院内感染，５７７４型（２４％）见于江西?
Based on the phage typing results of 3841 strains of Salmonella typhimurium, we analyzed the prevalence of Salmonella typhimurium phage in 14 provinces. Type 7774 (36.1%) was widely distributed and often ranked first in the country, mainly causing infectious diarrhea and also causing food poisoning and nosocomial infections. Peak in 1987 ~ 1991. Together with the largest food poisoning in 7774 in Yong’an, Fujian Province, in 1987, there were 1113 patients. Type 7776 (4 0%) prevailed in Xinjiang, the peak in 1993 (Kashi). Type 0774 (14.4%) was the most important bacteriophage that caused widespread nosocomial infections throughout Henan from 1989 to 1991. There were 504 (90.8%) isolates of 555 in Henan. 0776 type (0 9%) mainly in Xinjiang epidemic, often with 0774-type infection exist. 4774 (10.7%) was the most common phage type, causing a pandemic in Altay, Xinjiang in 1983, a hospital infection in Shanghai in 1986, four nosocomial infections in Liaoning in 1987-1991 and two food poisoning . Type 4776 (1.7%) and phage-type 4000 (2.6%) and 4002 (0.9%) associated with phase mutation are also frequently associated with Type 4774. Type 6774 (45%) was found in infectious diarrhea in Jiangxi, Fujian and eastern Inner Mongolia. Type 6776 (1.0%) was found in hospital in Hubei Province. Type 5774 (2.4%) was found in Jiangxi Province.
