Clarithromycin (CLA) and levofloxacin (LFX) have been recommended as the most effective antibiotics for treating Helicobacter pylori infection. However, the increase in H. pylori’s resistance to antibiotics is an alarming and growing challenge. The study aimed to determine the antimicrobial resistance profiles of H. pylori strains isolated from patients at the Hospital for Tropical Diseases and to detect point mutations in 23S ribosomal RNA (23S rRNA) and gyraseA (gyrA) genes. Point mutations in 23S rRNA and gyrA were detected using Sanger sequencing. Antibiotic resistance was tested by the microdilution method. Out of the 45 isolates, 44 (97.8%) were found to be resistant to at least one antibiotic, 38 (84.4%) resistant to metronidazole (MTZ), and all were sensitive to amoxicillin (AMX) and tetracycline (TET). Sixty percent of the isolated strains were resistant to 3-6 antibiotics; among them, multiple drug resistance (MDR) strains presented twenty percent resistance to more than two classes of antibiotics. Eleven strains (24.4%) carried two mutations associated with CLA and LFX but only nine of them were dual resistant to CLA and LFX, and twenty-four (53.3%) carried either CLA or LFX mutation. The point mutations A2143G in the 23S rRNA and N87K (Asn87Lys) in the gyrA were detected in the CLA and LFX resistant strains, respectively. The prevalence of MDR, especially CLA, MTZ, and LFX resistance, in the H. pylori isolates suggests that the use of these antibiotics need to be more considerable and cautious.
