Figure 1From: Evaluation in mice of Brucella ovis attenuated mutants for use as live vaccines against B. ovis infectionKinetics of splenic infection and spleen weight in mice inoculated with the vaccines. B. melitensis Rev 1 (Bme Rev 1; 1 × 105 CFU/mouse), B. ovis PNV25dA (Bov Δomp25d; 1 × 107 CFU/mouse), and B. ovis PNV22A (Bov Δomp22; 1 × 108 CFU/mouse) were used as vaccines. Results are expressed as means ± SD (n = 5) of the log CFU/spleen (A) or spleen weight (B) at each time-point.Back to article page
