Abstract

Bacteriophage PO4 has been found to depend on the presence of pili for the infection of its host organism, Pseudomonas aeruginosa. Unlike other pilus phages, which either contain RNA and are "spherical" or contain single-stranded DNA and are filamentous, PO4 has a head and a long noncontractile tail. This paper describes its basic characters, and a quantitative study is made of its adsorption to exponential-phase cells of piliated and nonpiliated strains of P. aeruginosa. PO4 is found to contain double-stranded DNA and appears to be virulent towards its two host strains.

摘要

已发现噬菌体PO4感染其宿主菌铜绿假单胞菌依赖于菌毛的存在。与其他菌毛噬菌体不同，其他菌毛噬菌体要么含RNA且呈“球形”，要么含单链DNA且呈丝状，而PO4有一个头部和一条长的非收缩性尾部。本文描述了其基本特征，并对其吸附到铜绿假单胞菌菌毛菌株和非菌毛菌株的指数生长期细胞进行了定量研究。发现PO4含有双链DNA，并且对其两种宿主菌株似乎具有毒性。
