Characterization of metronidazole resistant Helicobacter pylori
… of metronidazole resistant Helicobacter pylori (MtzR- Hp ) in relation to gastroduodenal disease is of concern. The study shows that MtzR- Hp is significantly higher in non-ulcer dyspepsia patients ( p = 0.005), expresses lower Le b ( p = 0.0365) and babA2 ( p = 0.03). RAPD profiles show …

Untersuchungen zu Adaptationsmechanismen des Magenbakteriums Helicobacter pylori
Das Bakterium Helicobacter pylori persistiert für lange Zeiträume im menschlichen Magen und ist im Rahmen der durch die Infektion induzierten Entzündungsreaktion dauerhaft toxischen Sauerstoffradikalen ausgesetzt, die von Immunzellen, wie neutrophilen Granulozy-ten und Makrophagen generiert werden. …

A molecular biological study on Campylobacter pylori
C. pylori have been shown to be associated with gastritis and peptic ulceration, but the mechanism of their pathogenicity is unknown. Since a number of virulence factors are known to be plasmid mediated, it was decided to study the plasmids of C. pylori. A variety of techniques were used to …

Characterization of Helicobacter pylori sRNAs HPnc2525, HPnc2600, and HPnc2645
<p>Helicobacter pylori is a common microaerophilic gram-negative bacterium that infects approximately 50% of the human population. Although all H. pylori infections result in inflammation of the gastric epithelium, only 10-15% of infections are symptomatic and progress to severe gastric diseases …

Regulatory CD4+FOXP3+ T cells in Helicobacter pylori-induced disease
Helicobacter pylori colonize the gastric or duodenal mucosa of approximately half of the worlds’ population. Although most individuals are asymptomatic, H. pylori infection cause peptic ulcers or gastric cancer in 10-15 % and 1-2 %, respectively, of the infected individuals. It has previously been …

Cloning and sequence analysis of plasmid DNA from Helicobactor pylori
The bacterium Helicobacter pylori is recognized as the cause of some types of gastritis and gastric ulcers. Many bacterial species contain plasmid DNA which encodes virulence factors, including antibiotic resistance, adherence factors, degradative enzymes, and toxins. The majority of H. pylori …
