QUINOLONES/ FLUROQUINOLONES

 

The Quinolones/ Fluroquinolones (chinolones, flumequine, fluoroquinolones) are a family of synthetic broad-spectrum antibiotic drugs. They inhibit the gyrase enzyme and are therefore also known as gyrase inhibitors.

Gyrase inhibitors are divided into four subgroups. The majority of quinolones belong to the subgroup of fluoroquinolones, which have a fluoro-group attached at the central ring system, typically at the 6th position. The fluoroquinolones belong to the so called second generation quinolones. Some of these are admitted as antibiotics in veterinary medicine for food producing animals. Fluoroquinolones are broad spectrum antibiotics against a lot of bacterial species. They are used frequently in veterinary medicine especially for cattle, pigs and chicken. The usage of fluoroquinolones has increased in the past years because large amounts of these antibiotics were applied to prevent infectious diseases, especially in chicken, swine and fish/shrimp farming. The wide use in food producing animals has generated microbial resistances. This led to an amendment of Council Regulation (EEC) No 2377/90 and in the introduction of MRLs (Maximum Residue Limits) for some fluoroquinolones.

EuroProxima Flumequine

Art. No.: 5101FLUM

Intended use:

A competitive enzyme immunoassay for screening and quantitative analysis of flumequine in various matrices.

General information:

Flumequine is a second-generation Quinolone antibiotic and is mainly active against Gram negative bacteria. In Europe the MRLs for Flumequine in the different matrices depend on the matrix and the species from which the matrix origins. MRLs vary from 200 μg/kg (muscle) to 1500 μg/kg (kidney). The antiserum used in the ELISA is specific for Flumequine and does not cross-react with any of the other Fluoroquinolones tested. For detection of most Fluoroquinolones in one test we advise the generic Fluoroquinolones ELISAs (5101FLUQG and 5101FLUQGII).

The Flumequine ELISA is a competitive enzyme immunoassay based on antibodies directed against flumequine.
