Description
Gatifloxacin is a fourth generation fluoroquinolone antibiotic with a significant degree of activity towards gram-negative bacteria and enhanced activity toward gram-positive bacteria. It is also potent in vivo against Staphylococcus aureus, Clostridium and many other anaerobic bacteria. Gatifloxacin has also exhibited strong bactericidal efficiency in penicillin resistant and sensitive Streptococcus pneumoniae and S. aureus.
Fluoroquinolones are a group of broad-spectrum antibiotics that inhibit DNA synthesis. These antibiotics prevent unwinding of double-stranded DNA by binding DNA gyrase or DNA topoisomerase. By preventing the formation of single-stranded DNA, fluoroquinolones inhibit bacterial replication.
Antibiotics are often used in clinical in vitro tests known as antimicrobial susceptibility tests or ASTs to determine their efficacy against certain bacterial species. They are tested against gram-negative and gram-positive bacteria using panels, discs, and MIC strips by medical microbiologists. ASTs decrease the risk of using an antibiotic against bacteria exhibiting resistance to it, and the results are used in clinical settings to determine which antibiotic(s) to prescribe for various infections.
