Method Purification of bacteriophages. Sequencing of isolated phage EC10. Plaque assays. Transduction and DNA transfer experiments. Viabilities of recipient cells determined by Direct Viable Counting (DVC). (cycling primed in situ amplification-fluorescent in situ hybridization [CPRINS-FISH]). Epifluorescence microscopy. Genetic characterization of transductants. PCR amplification of the unknown region next to the (beta lactamase gene-bla) bla sequence on transductants and sequencing. Examination of integration of bla gene into the phage genome.
Comments PFU=Plaque Forming Unit. Transduction frequencies determined by conventional plating were 3x10^(-8) - 2x10^(-6) gene/PFU
