Interestingly, co-localization of lactoferrin to WT or ΔT4 Lo-LCPs during solo-infections was not significantly different from the WT L. pneumophila positive control (ANOVA, P > 0.05) (Fig. 4A and C), suggesting that L. longbeachae does not evade specific granule fusion to its own phagosome, and nor do specific granules degrade L. longbeachae. Here, LTF is linked to infection.
