Morphological characterization of the Serratia marcescens bacteriophage SLP

SLP is a lambda-like bacteriophage specific for Serratia marcescens strains. Morphological studies have demonstrated that SLP virions present two cross-bar structures on its tail not described in bacteriophages specific for Enterobacteriaceae. SDS-polyacrylamide gel electrophoresis of major capsid proteins as well as electron micrographs are reported.
