噬菌体分型的方法是流行病学工作者深入研究伤寒流行过程中追查传染源,查找传播途径时是一种生物学分型方法。伤寒噬菌体型特别稳定、特异性强,目前国外已能把伤寒杆菌分成100多个不同的噬菌体型,在美、英等国得到广泛应用,国内开展此项工作不多。我们使用从国外引进的96型伤寒杆菌 Vi—Ⅱ分型噬菌体,对1978~1984年间收集的662株伤寒杆菌进行了鉴定研
Phage typing method is epidemiological workers in-depth study of typhoid fever in the process of tracing the source of infection, to find ways of transmission is a biological typing method. Typhoid bacteriophage type is particularly stable and specific, at present, foreign typhoid bacillus can be divided into more than 100 different phage-type, widely used in the United States, Britain and other countries, to carry out this little work in China. We used 96 types of typhoid bacillus Vi-Ⅱ phage introduced from abroad, 662 strains of typhoid bacillus collected between 1978 and 1984 were identified
