MAN2B1 and infection: The confocal microscopy data suggest that wbtA::Tn5, wzy::Tn5, manB::Tn5 and FTT0846::Tn5 strains were phagocytosed to the same extent as wild type, and did not colocalize with the Lamp-1 lysosomal marker, despite diminished intracellular growth at later stages of infection (Figure 6).
