Survival curve comparison of mice infected with A1a strains OK01-2528, MO02-4195, and Schu S 4 . C57BL/6 J mice (n = 7/strain) were challenged intradermally with 10–20 CFU of F. tularensis A1a strains OK01-2528 (▬ III ▬; red), MO02-4195 (▬; blue) and Schu S4 (▬ ▬; orange) and survival curves were modeled according to a Weibull distribution. The drop point for each mouse is shown in orange circles for mice infected with strain Schu S4, red triangles for mice infected with OK01-2528 and blue squares for mice infected with MO02-4195.
