Figure 1. Colonization kinetics of Salmonella enterica serovar Typhimurium purA ssaGH in systemically infected BALB/c mice.

Data are shown for spleen (A) and liver (B) of individual untreated mice (open circles), and mice that were treated from day two post infection with enrofloxacin (filled circles). Statistical significance of clearance at day 6 compared to day 4 were determined by t-test of log-transformed data (**, P<0.01; n.s., not significant).
