The bacteriophages ofPseudomonas aeruginosaFiltration measurements and electron microscopy

Abstract

Preliminary observations in a systematic study of fifteen bacteriophages isolated from Pseudomonas aeruginosa are described. The evidence as to size, morphology and plaque appearance indicates that this group of phages comprises several distinct types. The electron microscope reveals some of the phages to be simple spheres, but the majority are tailed particles.The importance of this group in the study of the phenomenon of lysogenicity is pointed out.
