16S rRNA mutation-mediated tetracycline resistance in Helicobacter pylori.
Most Helicobacter pylori strains are susceptible to tetracycline, an antibiotic commonly used for the eradication of H. pylori. However, an increase in incidence of tetracycline resistance in H. pylori has recently been reported. Here the mechanism of tetracycline resistance of the first Dutch tetracycline-resistant (Tet(r)) H. pylori isolate (strain 181) is investigated. Twelve genes were sele...
متن کاملEffects of 16S rRNA gene mutations on tetracycline resistance in Helicobacter pylori.
The triple-base-pair 16S rDNA mutation AGA(926-928)-->TTC mediates high-level tetracycline resistance in Helicobacter pylori. In contrast, single- and double-base-pair mutations mediated only low-level tetracycline resistance and decreased growth rates in the presence of tetracycline, explaining the preference for the TTC mutation in tetracycline-resistant H. pylori isolates.
متن کاملRT-PCR Detection 16S rRNA Novel Mutations Associated with Helicobacter pylori Tetracycline Resistance in Iran
Helicobacter pylori infection is chronic situation that increases the risk of development of peptic ulcer disease, mucosa-associated lymphoid tissue lymphoma (MALT), and gastric cancer. In many developing countries, such as Iran, H. pylori infect approximately 80 % of the population. Management of H. pylori infections is difficult, and relapse frequently occurs after successful eradication of t...
متن کاملDiversity of caprine and ovine Pasteurella multocida isolates based on 16S rRNA gene sequencing
In this study, to increase information about the relationship between caprine and ovine isolates of Pasteurella multocida, 16S rRNA gene sequencing of 9 goats (5) and sheep (4) isolates were investigated. Also, capsular type and toxAgene presentation was studied in this paper. All isolates, except one, belong to capsular type A, and toxA+ strain distributed among strains were isolated from both...
متن کاملDetection of Helicobacter pylori in hyperemesis
Introduction: Vomiting is one of the most common problems during pregnancy periods which happens in 50% of the pregnant women. Hyperemesis gravidarum is a rare status that 1 out of 500 pregnant women suffer from it. Although the reason of HG is unknown, but several studies indicate a relationship between HG and helicobacter pylori . So the aim of this study was to assess the relation between...
