Representative multiplex PCR for the amplification of <i>bla</i>_TEM, <i>bla</i>_SHV, <i>bla</i>_OXA, and 16S <i>rRNA</i> genes from culture of <i>E. coli</i> and biopsy and swab samples of 5 patients.

<p>Lanes 1–6; 1- <i>E. coli</i> JM109, 2-DF6S, 3-DF5S, 4-DF7S, 5-DF30T, and 6-DF40T, –Ve negative control (without template). M-100bp marker (New England Biolabs, USA). Template from the biopsy/swab samples also showed amplification depending upon the presence of respective genes.
