Examination of arachidonic acid as an anti-pneumococcal agent. (A) Examination of plasma fatty acids before and after infection with S. pneumoniae strain D39. (B) Examination of pneumococcal growth upon treatment with AA at 62.5, 125, or 250 μM. The OD600 was determined every 30 min. (C) Intracellular survival of pneumococci within THP-1 derived macrophages treated with 5 μM AA by comparison with untreated macrophages. All data are the mean of at least biological triplicates (±SEM) and where error bars are not visible this is due to occlusion by the shown symbols. Statistical analyses were performed using a Student's t-test (*p < 0.05).
