Abstract: | Six phages were isolated from sewage and from a lysogenic strain. Three of them, belonging to a new morphological group, had contractile tails and elongated heads with axial ratios of 2.4:1. Two phages, possessing short tails and very long heads with axial ratios of 3.5:1, were new isolates of an extremely rare group. Phages of both groups formed polyheads of various sizes and shapes. The last phage, 61 nm in diameter, seemed to have a tail-like appendage. All phages had double-stranded DNA, were active on enterobacteria only, and differed in their host range. The first five phages seemed to be Salmonella specific. |
