TNFα released due to antibiotic-mediated killing of S. pneumoniae. J774 macrophages were exposed to supernatants from bacteria treated for 2 hours with ampicillin, clinidamycin, or mock treated. TNFα production (mean ± s.d. of 6 wells from 4 consecutive, independent experiments) by the macrophages was determined by ELISA. An asterisk (*) indicates a significant difference (p < 0.05) by ANOVA compared to the other groups. There was no statistical differences between the ampicillin and control data.
