title: Evaluation of Escherichia coli host strain CB390 for simultaneous detection of somatic and F-specific coliphages.
abstract: Escherichia coli WG5, the strain recommended by the International Organization for Standardization (ISO) to detect somatic coliphages, was transformed to F(+) by introducing the plasmid Famp, which rendered it capable of simultaneously detecting both somatic and F-specific coliphages. Indeed, this strain, CB390, proved as effective in detecting similar numbers of phages as the sum of somatic and F-specific bacteriophages detected by the host strains recommended by both the ISO and the U.S. Environmental Protection Agency standardized methods.
