| Core Tip |
Mutations in 23S rRNA gene V domain of Helicobacter pylori (H. pylori) were studied in order to determine their association with therapeutic failure. In clarithromycin-resistant H. pylori isolated from individuals at high-risk of gastric cancer (GC) in Túquerres-Colombia and at low-risk of GC in Tumaco-Colombia, mutations A1593T1, A1653G2, C1770T, C1954T1, and G1827C in isolates from Tumaco, and A2144G from Túquerres were found. Mutations T2183C and C2196T from both cities were not associated with clarithromycin resistance. However, therapeutic failure of eradication treatment in the sampled Colombian populations was associated with mutations of 23S rRNA gene in clarithromycin-resistant H. pylori. |
