Viable counts of F. tularensis strains in PECa

Bacterial strainaNo. of bacteria (log10 CFU/well)b
0 h15 h
SCHU S43.91 ± 0.046.21 ± 0.03c
FSC0434.21 ± 0.104.67 ± 0.04

  • a The F. tularensis strain was allowed to infect the cells at a multiplicity of infection of 50.

  • b Data represent the mean log10 CFU±standard deviation of three cultures. One representative experiment out of three is shown.

  • c Significantly different (P < 0.05) from the CFU of strain FSC043 and the ΔFTT0918 strain by Wilcoxon's nonparametric test.

  • d Significantly different (P < 0.05) from the CFU of strain FSC043 by Wilcoxon's nonparametric test.
