Synthetic furanones inhibit quorum-sensing and enhance bacterial clearance in Pseudomonas aeruginosa lung infection in mice.
Antibiotics are used to treat bacterial infections by killing the bacteria or inhibiting their growth, but resistance to antibiotics can develop readily. The discovery that bacterial quorum-sensing regulates bacterial virulence as well as the formation of biofilms opens up new ways to control certain bacterial infections. Furanone compounds capable of inhibiting bacterial quorum-sensing systems have been isolated from the marine macro alga Delisea pulchra. ⋯ Synthetic furanone compounds inhibited bacterial quorum-sensing in P. aeruginosa and exhibited favourable therapeutic effects on P. aeruginosa lung infection.

Intra-abdominal infections: review of the bacteriology, antimicrobial susceptibility and the role of ertapenem in their therapy.
Complicated intra-abdominal infections require a combination of surgery/drainage and antimicrobial therapy that is active against both the aerobic and the anaerobic bacteria that comprise the intestinal flora. Ertapenem, a parenteral carbapenem, is highly resistant to a wide variety of beta-lactamase enzymes, and has a broad spectrum of activity against bacteria associated with community-acquired infections including those of complicated intra-abdominal conditions. This article reviews the bacteriology of complicated intra-abdominal infections, their antimicrobial susceptibility, especially to anaerobes, the utility of animal models in these mixed infections, and the supportive clinical trials and in vitro susceptibility data that show ertapenem to be generally well tolerated and as effective as either piperacillin-tazobactam or ceftriaxone plus metronidazole in the therapy of complicated intra-abdominal infections.
