Meropenem is a broad-spectrum carbapenem antibiotic with excellent activity against many pathogens associated with complicated skin and soft tissue infections (cSSTIs). At least three studies have shown meropenem to have good clinical efficacy and to be well tolerated in the treatment of cSSTIs.Background: Bacteroides fragilis ( B. fragilis) is an obligate anaerobe and generally acts as anti-inflammatory manner on the intestinal tract. Enterotoxigenic Bacteroides fragilis (ETBF), a subtype of B. fragilis, produces Bacteroides fragilis toxin (BFT) leading to either asymptomatic chronic colonic inflammation or colonic tumor formation.
Bacteroides is a genus of Gram-negative, obligate anaerobic bacteria. Bacteroides species are non endospore -forming bacilli, and may be either motile or nonmotile, depending on the species. [3] The DNA base composition is 40–48% GC. Unusual in bacterial organisms, Bacteroides membranes contain sphingolipids.

A survey of 6574 B. fragilis group isolates collected from 10 US medical centers confirmed that susceptibility rates differed widely ... Background & objective:. Bacteroides fragilis is a Gram-negative anaerobic opportunistic pathogen which is managed by empirical anaerobic coverage as a hospital norm. However, with rising reports of resistance among B. fragilis strains, antibiotic susceptibility testing for this pathogen may be the only way to understand the magnitude of the problem.
