FIG. 3.
Kinetics of recruitment of macrophages and neutrophils to the peritoneal cavity following infection with M. ulcerans. BALB/c mice were infected intraperitoneally with 6.1 log10 AFB of M. ulcerans 98-912 (▪) or 6.2 log10 AFB of M. ulcerans 5114 (•). Peritoneal cells were recovered by peritoneal lavage, and the total number of leukocytes was determined. Counting of neutrophils (solid lines) and macrophages (dashed lines) was performed on Hemacolor-stained cytospins. *, P < 0.05; ***, P < 0.001 (determined by Student's t test, comparing infected mice with mice inoculated with PBS). Results are from one representative experiment of two independent experiments. Error bars indicate standard deviations.
