Responses of various MGM isolates to V. vulnificus and cFP. A and B Effects of V. vulnificus cells and cFP on the survival of MGM strains. Various bacterial strains (MGM isolates listed in the Additional file: Table S2) were incubated under the conditions with 5.0 × 109 cells of V. vulnificus (A) or supplemented with cFP at concentrations of 1 and 4 mM (B). At 6 h of incubation, CFUs of the MGM strains were enumerated and presented with the percentage of each control (the same cultures but without treatment of V. vulnificus (A) or cFP (B)). The P-values for the comparison with the control (MGM only) are indicated (Student’s t-test; ns, not significant; *0.001 < P < 0.01). C TEM of P. goldsteinii cells. Four millimolar cFP was treated to the freshly grown culture of P. goldsteinii MGM002. At 6 h post-exposure to cFP, cells were processed for TEM analysis as described in the “Methods.” For comparison, a TEM image of no cFP-treated cells was presented in the left panel.
