Salmonella Typhimurium (ST) on MacConkey agar. ST isolate in broth was 10-fold serially diluted and mixed with a constant concentration of anti-Salmonella DNA aptamers in the form of rolling circle amplification (RCA) products. The colony-forming unit (CFU) was calculated and blotted with a concentration of the RCA products. The CFU was significantly reduced (p<0.001) in the lower dilution 1×10–4.
