Prevalence of extended spectrum beta-lactamase producing anaerobic bacteria in chronic periodontitis.

Objective: Due to the rampant use of antibiotics bacteria are acquiring resistance to penicillin group of drugs, which results in prescription failure in clinical practice. Beta-lactamase producing organisms are not only more virulent they also cause surrounding bacteria to become resistant. Hence, this study was undertaken to know the prevalence of extended spectrum beta-lactamase (ESBL) producing anaerobic bacteria in chronic periodontitis.
