Morphology of Staphylococcus saprophyticus bacteriophages.

The morphology of 6 bacteriophages isolated from Staphylococcus saprophyticus was studied by electron microscopy. Phages had isometric heads and non-contractile tails, thus belonging to the Siphoviridae family. They were subdivided into two morphological groups based on head diameter and tail length. Type I, represented by phages 1154A and 1405, and characterized by an unusually small capsid, may be a new species.
