Sir,
ABT-773, a novel ketolide, has demonstrated in vitro activity against a variety of anaerobic bacteria.13 While several studies have investigated the susceptibility profile of ABT-773, additional data on the activity of this new ketolide against anaerobes would be useful. The purpose of this study was to compare the in vitro bactericidal activity and post-antibiotic effect (PAE) of ABT-773 and co-amoxiclav against common anaerobes.
ABT-773 (Abbott Laboratories, Abbott Park, IL, USA) and co-amoxiclav (United States Pharmacopeia, Rockville, MD, USA) powders were prepared according to NCCLS guidelines or manufacturers recommendations.4 The antimicrobial concentrations studied were 2 x and
