Fig. 1From: Direct detection of Helicobacter pylori from biopsies of patients in Lagos, Nigeria using real-time PCR—a pilot studyThreshold cycle (ct) value indicated for reference H. pylori (J99) strain on the y-axis. There was no amplification for other bacterial pathogens including S. aureus, S. Typhimurium, P. aeruginosa and E. coli (x-axis) indicating specificity of primer/probe sets targeting 16S rRNA and ureA genes of H. pyloriBack to article page
