title: Activity of beta-lactamase produced by Bacteroides fragilis against newly introduced cephalosporins.
abstract: The purified beta-lactamase from Bacteroides fragilis hydrolyzed newly introduced cephalosporins including cefuroxime and HR 756, and was inhibited by 7 alpha-methoxylated cephalosporins such as 6059-S and YM09330.
