Fig. 1. V. cholerae uses its T6SS to target bacteria with specificity toward
Gram-negative species. Survival of rifampicin-resistant Gram-negative bacterial
prey is shown: (A) E. coli K-12 MG1655 (red), S. Typhimurium (green), C.
rodentium (blue), and P. aeruginosa (orange) and (B) E. coli K-12 MG1655
(red), EHEC (purple), and EPEC (orange) were determined by measuring cfu
following exposure to the indicated rifampicin-sensitive predator listed on
the x axis with each prey exposed to predatory self, V52, and V52ΔvasK. The
data represent three independent experiments.
