Bacterial numbers in the air pouch exudates from GAS-infected mice with or without dextromethorphan treatment. Dextromethorphan (12.5 mg/kg) was intraperitoneally administrated to mice 30 min before and 1, 12, and 24 h after NZ131 inoculation (3 × 108 CFU) in the air pouch. Mice were sacrificed 24 h (n = 10 per group of GAS with saline and n = 9 per group of GAS with DM) and 48 h (n = 11 per group of GAS alone and n = 12 per group of GAS with DM) after NZ131 infection, and the air pouch exudates were collected. The bacterial numbers were determined by plate counting (*, P < 0.05).
