Avoiding fluoroquinolone resistance
Postgraduate Medicine, 1997The therapeutic usefulness of fluroquinolones for serious and difficult-to-treat infections is well documented. However, with increasing reports of organisms becoming resistant to the agents (most often the pseudomonads, staphylococci, and streptococci), the usefulness of this class of antibiotics is being threatened.

Bacterial resistance to fluoroquinolones: Lessons to be learned
Infection, 1994Resistance to fluoroquinolone antibacterials has emerged in a limited form, largely amongst certain specific species and often restricted to single clones of these pathogens. Mediated by chromosomal mutation, the major mechanisms are alterations in gyrase subunits and reduced penetration associated with decreased outer membrane protein production ...

Mechanisms of Resistance to Fluoroquinolones
Drugs, 1995This paper gives an update on the mechanisms of bacterial resistance to fluoroquinolones. The laboratory techniques currently used to determine the mechanism(s) of resistance are outlined, including the use of restriction fragment length polymorphism and single-stranded conformational polymorphism analysis of mutations in gyrA. Alterations in gyrA have

Resistance to Quinolones and Fluoroquinolones
1989The quinolone class of oral antimicrobial agents has enjoyed rapid expansion and development over recent years and a revival in interest in the earlier agents nalidixic and oxolinic acid. The quinolone class (which includes 4-pyridone antibacterials) share the 4-quinolone nucleus and also a carboxylic acid substituent at position 3 (Fig. 1). During the

Mechanisms of resistance to fluoroquinolones.
The National medical journal of India, 1999Fluoroquinolones have some of the properties of an 'ideal' anti-microbial agent. Because of their potent broad spectrum activity and absence of transferable mechanism of resistance or inactivating enzymes, it was hoped that clinical resistance to this useful group of drugs would not occur.
