Antibiotic Resistance Results of Helicobacter pylori in a University Hospital: Comparison of the Hybridization Test and Real-Time Polymerase Chain Reaction

Figure 1

Patients who were H. pylori positive and negative with the Genotype® HelicoDR (Hain Life Science, Germany) kit. In the left patient HP band seen, the banding in the gyr87 MUT region is indicating a mutation in the gyrA region, that is, it is resistant to fluoroquinolone; at the same time, the region of 23S with the WT in the MUT1 band is seen in the band, i.e., we can say that H. pylori strains isolated from this disease are resistant to clarithromycin. In the patient in the middle, the HP band can be seen but gyrA and 23S bands cannot be seen. We can say that this patient is H. pylori positive. In the right patient, there is no band except for the control and amplification band, meaning that the patient has been evaluated as H. pylori negative.
