title: Phage beta interaction with Vibrio cholerae.
abstract: The role of temperate phage beta in determining the serology and eltor-lytic phage sensitivity in Vibrio cholerae was investigated. The only serological change found in six host strains was a change to roughness. This was accompanied by failure to adsorb several of the lytic phages. Various phage-sensitivity changes were induced by phage beta in two hosts at the post-adsorption level. In strain HP47, three types of progeny were obtained of which one was universally resistant to lytic phages. These untypable lysogens were culturally stable but gave rise to segregants of the rare phage-type 6 on single colony selection.
