The effect on the nasopharyngeal flora of 7 days of amoxicillin-clavulanate or 5 days of 800 mg once a day was studied in 50 adults with acute sinusitis. The numbers of potential pathogens and interfering alpha-hemolytic streptococci were equally reduced after both therapies. However, the number of interfering Prevotella spp. declined more significantly after amoxicillin-clavulanate treatment.
