Clearance of S. aureus by MSR-A−/− and MSR-A+/+ mice. 107 CFU S. aureus (Cowan I) were injected into the peritoneal cavity of four MSR-A−/− and four MSR-A+/+ mice. (A) At the indicated times, the peritoneum was lavaged and its content of viable bacteria was determined by plating serial dilutions on agar plates. (B) Viable bacteria in the blood were determined after collecting blood via cardiac puncture of killed animals and subsequent plating on agar plates at the indicated times. Data represent the mean of three experiments.
