Figure 5. Direct high-throughput multiple genetic detection system can efficiently distinguish multistrain infection in gastric biopsy specimens.
(A) The peaks of wild-type pbp1A_A and mutant resistance genes pbp1A_A/G were appeared at 154 and 159 bp in biopsy specimen. (B) The peak of wild-type pbp1A_A appeared at 154 bp in the corresponding isolated strains. 23S rRNA_G, rdxA_C and gyrA_C had the single peak in biopsy specimen and corresponding isolated strains, appeared at 180, 253 and 306 bp, respectively. Human internal control β-globin had the specific peak appeared at 199 bp in biopsy specimens.
