A 2% (w/v) agarose gel of 16S rRNA gene fragments amplified from E. coli and Klebsiella isolates as well as E. coli (ATCC 25922) and K. pneumoniae (ATCC 13883) control strains. Lane M = DNA marker (1 kb O'GeneRuler DNA marker), Lane 1 = E. coli (ATCC 25922), Lane 2 = K. pneumoniae (ATCC 13883), Lanes 3–19 = 16S rRNA gene fragments of E. coli isolates from cattle faeces and beef samples, Lanes 20–38 = 16S rRNA gene fragments of K. pneumoniae isolates from cattle faeces and beef samples.
