    Fluoroquinolone use and chloroquine resistance development

    According to legend it was first brought to Europe by a Countess who had been treated with it in Peru in the 1600s. In 1820, two French chemists isolated quinine from the cinchona bark and quinine became a treatment of reference for intermittent fever throughout the world.

    The widespread use of fluoroquinolones has contributed to the rapid emergence of resistance worldwide. As we see from ResistanceMap, In the United States, fluoroquinolone resistance has increased significantly over the past decade, exceeding 25% resistance in outpatient E. coli samples in some areas. S typhimurium with decreased susceptibility to fluoroquinolones and Campylobacter resistant to fluoroquinolones have been isolated from animals and retail poultry. 10,11 For these reasons the use of fluoroquinolones in veterinary medicine has caused concern, as such strains can infect man. A fluoroquinolone is often the drug of choice for. Request PDF Fluoroquinolone Resistance Fluoroquinolones trap gyrase and topoisomerase IV on DNA as ternary complexes in which the DNA is broken. The complexes, called cleaved complexes.

    These compounds belonged to a new class of antimalarials, the four-amino quinolines. Research by German scientists to discover a substitute for quinine led to the synthesis in 1934 of Resochin (chloroquine) and Sontochin (3-methyl-chloroquine).

  5. Because the use of broad-spectrum antibiotics encourages the spread of multidrug-resistant strains and the development of Clostridium difficile infections, treatment guidelines often recommend minimizing the use of fluoroquinolones and other broad-spectrum antibiotics in less severe infections and in those in which risk factors for multidrug resistance are not present.

    Fluoroquinolones are used by hospitals as “first-line” antibiotics. If a patient becomes sick with an opportunistic infection, it is not good to have encouraged the persistent bacteria to have developed a resistance to fluoroquinolones potentially due to previous over-use of the drugs Despite prescribing guidelines now recommending reserving fluoroquinolone use, resistance continues to rise and is a major problem encountered in the clinical setting. The percentage of E. coli isolates in the UK resistant to fluoroquinolones rose from 6% to 20% from 2001 to 2006 and remained at about 17% for the rest of the decade If you are new to hearing about the dangers of the Fluoroquinolone drugs, then this introduction is for you. There are actually several different drugs that make up this class that include antibiotics and antimalarial drugs. These antibiotics are the primarily the subject of this website and many others because they are some of the most
