Intracellular survival of wild type or ΔabcBA Brucella ovis mutant in HeLa cells.

HeLa cells infected with MOI 1:1000 of WT or ΔabcBA of B. ovis and intracellular infection measured at 0, 8, 24, and 48 hours post infection (hpi). Data represent geometric mean and standard error of three independent experiments (***p<0.001).
