Cell size comparisons of wild-type, Δ<i>dgcC</i>, <i>dgcC</i> wild-type GGEEF-complemented and <i>dgc</i>CGGAAF “complemented” <i>Bdellovibrio</i> strains.

<p>Histograms show the mean A: length and B: width measured from negatively strained electron microscope images of a minimum of 50 cells per strain. Error bars show one standard deviation above and below the mean. The lengths of each of the mutant and complemented strains was significantly shorter than wild-type (p<0.001) but for the widths, the strain complemented with the wildtype <i>dgcC</i> gene which was not significantly wider than wild type, but the mutant strain was significantly (p<0.001) wider; with the <i>dgcC</i>GGAAF complemented strain being of intermediate width.
