Fig 1. Transformation rate in H. pylori correlated with the fraction of cells with active outer membrane DNA transport.

Fig 1

Cell suspensions were derived from the experiments illustrated in Fig 4. Bacteria with different competent fractions of cells were taken during or after competence development; non-competent cells were taken before competence development. H. pylori N6 were incubated in parallel with either Cy3-labelled λ DNA or a PCR fragment of rpsL(A128G), conferring streptomycin resistance. The data show the principle suitability of measuring the fraction of cells with active outer membrane DNA transport for the evaluation of competence development. Cumulative data from 13 independent experiments (n = 42).
