Abstract

Seventeen pure lines of S. typhi bacteriophages have been obtained from mother races O and Vi; of these, three were used to study 152 S. typhi strains with a view of detecting their DNA host specificity systems. 10 S. typhi strains having the DNA host specificity system have been detected by the rough determination of the lytic spectrum and the cross titration of phage Vi IX.

摘要

从O型和Vi型母系噬菌体中获得了17株伤寒沙门氏菌噬菌体纯系；其中3株用于研究152株伤寒沙门氏菌菌株，以检测它们的DNA宿主特异性系统。通过粗略测定裂解谱和噬菌体Vi IX的交叉滴定，已检测出10株具有DNA宿主特异性系统的伤寒沙门氏菌菌株。
