a Agarose (1.5%) gel electrophoresis of PCR products of the amplified 110 bp 16S rRNA gene. Lane 1 and 13: molecular weight markers (100 bp); lane 2: positive control (J99); lane 3: negative control (nuclease-free water); lanes 4–12: positive isolates. b Agarose (1.5%) gel electrophoresis of PCR products for cagA (981 bp) detection. Lane 1: 100 bp gene ruler, Lanes 2: cagA positive control, lane 3: negative control, lanes 4–14: cagA positive isolates. c Agarose (1.5%) gel electrophoresis of PCR products for dupA (971 bp) detection. Lane 1: 100 bp gene ruler, Lanes 2: dupA positive control, lane 3: negative control, lanes 4–14: dupA positive isolates. d Agarose (1.5%) gel electrophoresis of PCR products for vacA m1 (290bp) detection. Lane 1: 100 bp gene ruler, Lane 2: vacA m1. positive control, lane 3: negative control, lanes 4–14: vacA m1 positive isolates
