FIG. 6.
Transfer frequencies of generalized transducing lysates of all six phages. The following three phenotypic markers were investigated: kanamycin resistance (A), streptomycin resistance (B), and rifampin resistance (C). The symbols indicate the mean transfer frequencies (i.e., the numbers of transductants per recipient bacterium) recorded for each marker. The dashed lines show the limits of detection for each marker. MSD, minimum significant difference.
