Efflux-mediated resistance to fluoroquinolones in gram-negative bacteria.
The introduction of the fluoroquinolones (FQs) in the 1980s provided clinicians with a class of broad-spectrum agents applicable to a range of gram-negative infections including urinary tract infections, gastrointestinal infections, respiratory tract infections, sexually transmitted diseases, bone and joint infections, and infections of the skin and soft tissue (reviewed in references 10 and 43...
متن کاملMultidrug efflux pumps of gram-negative bacteria.
Gram-negative bacteria tend to be more resistant to lipophilic and amphiphilic inhibitors than gram-positive bacteria. Such inhibitors include dyes, detergents, free fatty acids, antibiotics, and other chemotherapeutic agents. This property is used in the selective enrichment of gram-negative bacteria, especially of members of the family Enterobacteriaceae, for example with MacConkey agar (cont...
متن کاملPresence and dissemination of the multiresistance gene cfr in Gram-positive and Gram-negative bacteria.
The emergence of the multiresistance gene cfr in staphylococci is of global concern. In addition to conferring resistance to phenicols, lincosamides, pleuromutilins, streptogramin A antibiotics and selected 16-membered macrolides, the cfr gene also confers resistance to the oxazolidinone linezolid. Linezolid is a last-resort antimicrobial agent for the treatment of serious infections in humans ...
متن کاملMechanism of antibiotic efflux in Gram-negative bacteria.
Active efflux of antibiotics mediated by multidrug transporters is a mechanistic basis of multidrug resistance in bacteria. The most versatile multidrug transporters are those found in Gram-negative bacteria. They have a high level of constitutive expression and provide an immediate response to structurally diverse antimicrobial agents including clinically important antibiotics. The versatility...
متن کاملThe carbon source influences the efflux pump-mediated antimicrobial resistance in clinically important Gram-negative bacteria.
OBJECTIVES Multidrug efflux pumps are proteins known to play an important role in resistance in bacteria. These proteins are located in the inner membrane (IM), together with many other proteins, including inducible permeases that participate in the uptake of non-phosphotransferase system (PTS) carbohydrates (i.e. carbohydrates uptaken by mechanisms other than the PTS). However, lipid bilayer s...
