Figure 4From: Global transcriptional profiling of Burkholderia pseudomallei under salt stress reveals differential effects on the Bsa type III secretion systemInvasion of A549 epithelial cells by B. pseudomallei. A549 cells were infected with an overnight cultures of B. pseudomallei K96243 grown in in NaCl-free LB broth (open bar), LB broth with 170 mM NaCl (solid bar), or LB broth with 320 mM (striped bar). Intracellular bacteria were counted after lysing infected cells at 4 hrs-post-infections. Asterisks indicate significant differences (P value < 0.05, t-test) between groups. Error bars represent standard errors of the means for experiments performed in triplicate.Back to article page
