TNF-α expression during S. aureus infection. Mice were inoculated intraperitoneally with wild-type S. aureus, a protein A-deficient mutant (spa-deficient mutant), or PBS (control), and TNF-α expression by peritoneal cells at the times indicated was quantified by real-time PCR and was normalized to GAPDH expression. Each bar represents the mean and standard deviation for 3 to 5 mice. Asterisks indicate significant differences (*, P < 0.05) by Student's t test. n.s., not significant.
