Rapid diagnosis of septic arthritis using 16S rDNA PCR: a comparison of 3 methods.

Few studies address the utility of molecular techniques for diagnosis of infection in synovial fluid (SF). We evaluated 3 different methods using 16S rDNA polymerase chain reaction (PCR) on 63 specimens for the diagnosis of joint infection. SF samples were classified as normal, inflammatory, or septic based on the patient's clinical and laboratory results.

Antimicrobial activity and a comparison of published pharmacodynamics of gemifloxacin and eight fluoroquinolones against Streptococcus pneumoniae.

Gemifloxacin was evaluated for its in vitro activity and was compared with eight fluoroquinolones. Pharmacodynamic comparisons were made based on published pharmacokinetic information. Gemifloxacin demonstrated excellent in vitro activity (minimum inhibitory concentration necessary to inhibit 90% of the strains tested, MIC90 = 0.

Broad-range bacterial polymerase chain reaction for early detection of bacterial meningitis.

The diagnosis of bacterial meningitis often depends on isolation of bacteria on culture, which may take 24-48 h. DNA amplification techniques could provide rapid diagnosis, which would guide the clinician in antimicrobial therapy decisions. This study determined the clinical utility of polymerase chain reaction (PCR) for the diagnosis of meningitis with use of a broad range of bacterial primers.
