Abstract
Eighteen phages were studied by electron microscopy. They belonged to eight morphotypes representing the Myoviridae, Siphoviridae and Podoviridae families of tailed phages. Twelve phages were members of known species and six phages belonged to three new species. Results correlated closely with serological and DNA-DNA hybridization data. Induced and non-induced propagating bacteria were investigated for lysogeny. All strains produced R-type pyocins, phage-like particles or inhibitory reactions. The identity of typing phages should be controlled periodically.
Dix-huit phages sont étudiés au microscope électronique. Ils sont caudés, appartiennent à huit types morphologiques et représentent les familles des Myo-, Sipho-, et Podoviridae. Douze phages appartiennent à des espèces connues et six phages, à trois espèces nouvelles. Il y a une étroite corrélation entre la morphologie, la sérologie et l'hybridation de l'ADN des phages. L'état lysogène des bactéries propagatrices est étudié avant et après induction. Toutes les souches produisent des pyocines du type R ou des particules phagiques, ou encore, montrent une action inhibitrice. L'identité de phages de lysotypie doit être contrôlée périodiquement.
