Figure 2. Peritoneal clearance of K. pneumoniae is enhanced in mice previously infected with N. brasiliensis.

C57BL/6 (WT) and C57BL/56 mice infected 2 weeks earlier with N. brasiliensis (Nippo Mice) were injected i.p. with 150 CFU of K. pneumoniae. Dilutions of peritoneal lavage fluid obtained 4 (A) and 24 h (B) after K. pneumoniae injection were cultured on agar plates and bacterial colonies were counted. (n = 7–9 mice/group, *P<0.05).
