Figure 1: Phenotypic and molecular analyses of bacterial isolates. (a) Representative result of the boronic-acid based assay to identify AmpC-producing isolates with FOX (cefoxitin alone) and FOX + BA (cefoxitin + boronic acid) test discs. (b) Representative gel electrophoresis result of polymerase chain reaction products derived from bacterial isolates with the presence of 405 base-pair (bp) products (DHA gene) in lanes 1–3. Lane N represents water negative control and lane L contains the molecular ladder
