title: Effect of carbon dioxide and pH on susceptibility of Bacteroides fragilis group to erythromycin.
abstract: We examined the effects of pH and incubation in a CO(2)-containing atmosphere on the activity of erythromycin against 81 strains of the Bacteroides fragilis group. A striking reduction in erythromycin activity was noted when the pH decreased below 7.0 and when the organisms were incubated with CO(2).
