Figure 3. Representative agarose gel electrophoresis of PCR products confirming the presence of bla and qnr resistance genes in environmental Enterobacteriaceae isolates. a : PCR amplification of the bla-TEM gene (840 bp) in lake water isolates. Lane M: molecular size marker; lanes LW1–LW5: lake water samples. b: PCR amplification of the bla-TEM gene (840 bp) in gutter water isolates. Lane M: molecular size marker; lanes GW1-GW5: gutter water samples. c: PCR amplification of qnrA (543 bp), qnrB (469 bp), and qnrS (417 bp) genes in chicken fecal isolates. Lane M: molecular size marker; lanes CF1–CF5: chicken fecal samples. d: PCR amplification of the qnrA gene (543 bp) in pig fecal isolates. Lane M: molecular size marker; lanes PF1–PF5: pig fecal samples
