OMVs from a V. cholerae wave 3 pandemic strain neutralizes all three ICP phages. Titration of V. cholerae HC1037 OMVs on a fixed concentration of prey (HC1037) and ICP1, ICP2, and ICP3 (∼10,000 PFU). n = 3 for all. The horizontal solid lines indicate means ± standard deviations. *, P = 0.0076 for ICP1 and P = 0.0093 for ICP3; **, P = 0.02 for ICP2.
