Scientists at St. Jude Children's Research Hospital have demonstrated a more effective treatment for bacterial pneumonia following influenza. They found that the antibiotics clindamycin and azithromycin, which kill bacteria by inhibiting their protein synthesis, are more effective than a standard first-line treatment with the "beta-lactam" antibiotic ampicillin, which causes the bacteria to lyse, or burst. The finding is important because pneumonia, rather than the influenza itself, is a principal cause of death from influenza in children and the elderly. During pandemics—such as the one that may arise from avian influenza—up to 95 percent of influenza deaths are due to pneumonia....
