Electrophoresis result for multidrug-resistant and extended-spectrum beta-lactamase–producing E. coli strains isolated from dairy cattle in Tulungagung, Indonesia. MRK – M-marker; K + TEM – positive control for blaTEM gene with E. coli ATCC35218); K + CTX – positive control for blaCTX-M gene with E. coli WHO 21.4.; K – negative control with E. coli ATCC 25922; TS7, TS27 and TS42 – multidrug-resistant E. coli confirmed double-disc synergy test–negative isolates containing the blaTEM gene (indicated by a single band of 1.086 base pairs); TS11 – multidrug-resistant E. coli confirmed double-disc test–positive isolate containing the blaCTX-M gene (indicated by a single band of 550 base pairs)
