β‐Lactamase production and antimicrobial susceptibility of subgingival bacteria from refractory periodontitis
24 Aug 2004
Abstract excerpt
This study assessed the extent of beta-lactamase-producing bacteria in subgingival plaque samples obtained from 25 patients with refractory marginal periodontitis in the USA. beta-Lactamase-positive isolates were characterized using commercial diagnostic kits and partial sequencing of the 16S rRNA gene. The susceptibilities to different antimicrobial agents were tested and, in addition, the isolates were screened...
