Abstract excerpt

OBJECTIVE: To investigate the mixed infection of clarithromycin susceptibility and genotype of Helicobacter pylori resistant strains. METHODS: Ten single colonies were picked randomly from each of 16 resistant strains. Genomic DNA was prepared from single colony isolates and their parental clarithromycin-resistant strains by the hexadecyltrimethylammonium bromide (CTAB)-phenol extraction method. Susceptibilities...
