A gerbil model of acute otitis media induced by Streptococcus pneumoniae plus Haemophilus influenzae was used to assess the efficacy of amoxicillin/clavulanic acid (A/C) (1.5/0.3, 2.5/0.5 and 10/2 mg/kg) and erythromycin (2.5, 10, 20 and 50 mg/kg) with or without acetaminophen. The amoxicillin/clavulanic acid MIC was 1/0.5 mg/l for both organisms and the erythromycin MICs were 0.12 and 4 mg/l for S. pneumoniae and H. influenzae, respectively. The organisms were inoculated directly into the middle ear (ME) and antibiotic treatment started 2 h post-inoculation and continued at 8h intervals for three doses. Acetaminophen was administered at 50 mg/kg. Samples for bacterial counting were obtained from the ME on day 2. Amoxicillin/clavulanic acid peri-MIC concentrations in ME were effective in eradicating both organisms. Despite the inflammation induced by S. pneumoniae, erythromycin did not eradicate H. influenzae at ME concentrations (2.4 mg/l for erythromycin 50 mg/kg) higher than those obtained in humans but lower than the MIC.
