Fig. 4From: Repurposing carvacrol, cinnamaldehyde, and eugenol as potential anti-quorum sensing agents against uropathogenic Escherichia coli isolates in Alexandria, EgyptRepresentative agarose gel showing PCR amplification of usp gene in selected E. coli isolates. Lanes 1 and 2 correspond to a DNA molecular marker (100Â bp). Lanes 3, 4, 5, and 7 show the amplicon (435Â bp) corresponding to usp gene in E1, E2, E3, and E10 isolates, respectively. Lane 6 corresponds to the result of E5, a non-usp-harbouring isolateBack to article page
