Influence of anti-FloR antibody on florfenicol accumulation in florfenicol-resistant Escherichia coli and enzyme-linked immunosorbent assay for detection of florfenicol-resistant E. coli isolates.

ABSTRACT: To detect florfenicol-resistant Escherichia coli isolates by enzyme-linked immunosorbent assay (ELISA), anti-FloR1 antibodies were produced in mice using a recombinant glutathione S-transferase (GST)-FloR1 protein, which was expressed in a prokaryote expression system, as the antigen. The specificity of the murine anti-GST-FloR1 antibody and its influence on florfenicol accumulation in florfenicol-resistant isolates were investigated using Western blotting and high-performance liquid chromatography, respectively. Western blotting using the anti-FloR1 antibody showed specific binding of the antibody to the florfenicol-resistant FloR protein. Preincubation of florfenicol-resistant strains with the antibody significantly increased the intracellular accumulation of florfenicol and enhanced the
