摘　　要：使用９６型伤寒Ｖｉ－Ⅱ噬菌体对我国１４省、市多年来收集的３２２８株伤寒沙门氏菌进行了分型研究，分得３６个型，分型率为８７．１１％。其中以Ｍ１为主要流行型，占３８．８８％，曾分别在贵州、江苏、河南、湖北和浙江等地引起水型暴发流行；Ａ、Ｂ１和Ｄ２型分布较广；并发现了Ｍ３、４２、４９、５０、５１等目前国内未见报道的新型别。该研究结果对追踪传染源。3228 strains of S.typhi collected from 14 provinces were identified by using 96type ViⅡ phage.In total,thirty six types were found and the typing rate was 87.11%.The M1 was the main type and was about 38.88% of the total strains.It was found that M1 type has caused outbreaks of typhoid fever in Guizhou,Jiangsu,Henan,Hubei and Zhejiang provinces.The distributions of A,B1 and D2 types were wilder than that of others.Five types of them were firstly isolated in China.The data provided scientific basis for tracing sources of infection,searching factors of transmission and taking correct preventive measures in control of typhoid fever.
