Abstract

SUMMARY: The major characteristics of a temperate phage specific, as far as is known, for one strain of serotype 04 have been described. It is inactivated by ultraviolet light at a rate characteristic of temperate phages, and it is serologically unrelated to the P1, P22 and T phages. This phage (designated ø 04-CF) is short-tailed, contains DNA, is about 55 mμ, needs no supplemental Ca or Mg for adsorption, shows a latent period of 46 min. and a burst size of 166, and is ultraviolet light inducible. Phage 04-CF can transduce markers to the susceptible indicator strain of (CF 2004-6). The variety of markers transduced indicates that this is another generalized transducing system for . The frequencies of transduction lie between 10 and 10 for different markers, but vary with phage multiplicities. This strain of also acts as recipient in matings with K 12 strains.
