Co-culture of prey bacteria with <i>N</i>. <i>gonorrhoeae</i>.

Prey bacteria were incubated alongside either wild-type <i>N</i>. <i>gonorrhoeae</i> (WT FA1090, black bars) or the Δ<i>napRABC</i> strain (blue bars) for 3 or 24 h in FB medium at a 1:1 ratio. Prey bacteria were then recovered selectively on agar plates and CFU/ml were counted. Data were normalised against the recovery of prey bacteria grown without the gonococcus (100%). The data underlying this figure can be found in <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.3003001#pbio.3003001.s019" target="_blank">S7 Data</a>. Multiple paired <i>t</i> test were performed between each pair (WT vs. Δ<i>napRABC</i>) with no significant difference in their survival (<i>n</i> = 3, error bars, SD). (PDF)
