Intracellular replication of F. tularensis strains in J774.1 macrophages. Gentamicin protection assays were utilized to assess replication of F. tularensis strains in J774.1 murine macrophages. Macrophage monolayers were infected with an MOI of 100 and cells were lysed and plated to enumerate CFU at 4 and 24 h post-infection. The percent CFU increase from the 4 h to 24 h time point was calculated. No statistical significance in percent increase was observed via t-test.
