FIG. 2.
(A) Comparison of the intracellular survival of B. suis 1330 wild-type containing plasmid pBBR1MCS (•), the ΔeryC deletion mutant with plasmid pBBR1MCS (▵), and ΔeryC complemented with pBBR1-eryC (▴) in human THP-1 macrophage-like cells. Results are displayed as means ± SD, and one out of two experiments performed in triplicate (each) is shown. (B) Growth curves of wild-type B. suis 1330 (•) and B. suis ΔeryC (▵) in RPMI 1640 medium with 10% FCS, where bacterial growth was measured by monitoring OD600 increase.
