Fig. 4From: Evaluation of multiplex ARMS-PCR for detection of Helicobacter pylori mutations conferring resistance to clarithromycin and levofloxacinClarithromycin and levofloxacin resistance mutations detected in the 74 positive samples. Sanger sequencing revealed the precise mutations associated with antibiotic resistance. There was a strong positive correlation of specific 23S rRNA and gyrA mutations with a positive ARMS-PCR result for clarithromycin and levofloxacin resistanceBack to article page
