Morphological Characteristics of Three New Actinophages

open access: yesJournal of General Virology, 1967
Summary Three newly isolated strains of Streptomyces phages have been examined by electron microscopy using the negative-staining technique. These phages have polyhedral heads and noncontractile tails ending in a clearly distinct fixation structure. They differ in their dimensions, head outline, flexibility of the tail and type of fixation plate.
