Abstract

Antibiotic resistance in Helicobacter pylori is increasingly more common and can lead to treatment failure. This study used the Etest and Sanger sequencing techniques to determine the minimum inhibitory concentration (MIC) and mutant forms of Helicobacter pylori in patients with gastritis and peptic ulcer disease in Tien Giang province, Vietnam. The relationship between the MIC and levofloxacin-resistant mutant forms of H. pylori was also explored. Results showed that GyrA mutations accounted for 60% of the total 65 samples studied. Among these mutations, 23.1% (9/39) of LEV-sensitive samples with a MIC of LEV ≤ 1 µg/ml had mutations at codon positions P188L, R190Q, M191I, Y81C, P187S, D91T, D108E, R95K, G111A, and S185Y; and 30/39 (66.9%) samples with MIC > 1 µg/ml were found to have mutations at positions N87K, D91N/G, A55S, M191I, Y28F/I, V107F, A27L, V199G, S29F, M30L, G111L, R42K, V65S, A66L, S101L, M102A, N112I, R95G/K, D108V/E, and A94G. This study suggested that mutations in GyrA at codon positions N87K, D91N/G/T, and A55S of H. pylori were associated with increased MIC concentration of levofloxacin. The related mutations M191I, Y28F/I, V107F, A27L, V199G, S29F, M30L, G111L, R42K, V65S, A66L, S101L, M102A, N112I, R95G/K, D108V/E, and A94G on GyrA were not identified. Further research on the LEV resistance of H. pylori in Tien Giang is needed.
