Morphology of SL7207-pEGFP. Wild type SL7207 and SL-pEGFP were grown in culture to mid-log phase, Gram-stained and examined by light microscopy. Representative light microscopy images of Gram-stained SL7207 cultures, both wild type and SL-pEGFP (a). Scale bars 10 µm. The mean length of individual bacteria (b). Quantification of the proportion of SL7207 in culture which were filamentous (>6 µm; c). Results displayed are the average of at least two independent biological replicates. Error bars SEM. Representative Gram-stains are shown for each culture. Statistical analyses performed using a Students t test where p < 0.01**
