A microbiological study of acute maxillary sinusitis in Bloemfontein.

Microbiological analyses and antibiotic sensitivity tests were done on 26 patients with acute maxillary sinusitis during the first 9 months of 1986. Positive cultures were obtained in 23 of the patients, with anaerobes cultured in 13 (50%). Haemophilus influenzae was cultured in all non-producers of beta-lactamase. Therapy with erythromycin and chloromycetin appeared to be equally effective in aerobic cases and metronidazole was effective in all anaerobic cases.
