Phage H, thought to be specific for Pasteurella pestis, was shown to plate efficiently on F- strains of Escherichia coli but not on F, F, or Hfr strains. The phage was adsorbed rapidly to F- strains but was not adsorbed to strains carrying F. Comparison with seven other reported female-specific phages showed that, although phage H was similar to the other phages in some characteristics, the exceptionally low efficiency of plating 10 to the minus 9th power on F-containing cells makes phage H a particularly useful female-specific phage.
