Phenotypic characterization of the NmΔrecG mutant.

A. Immunoblot of cell lysates from Neisseria meningitidis (Nm) Mc58 wildtype and a Mc58ΔrecG mutant detected with anti-RecG antiserum. B. Colony morphology of M1080 wildtype and M1080ΔrecG null mutant of grown overnight at 34°C, showing normal size colonies for the wildtype (i and iii), whereas the mutant strain shows normal size colonies together with small size colonies (ii and iv). C. Graphical presentation of the colony size measurement (area in mm2) of the Nm wildtype strains and NmΔrecG Mc58 and M1080 mutant strains.
