Objective(s): Treatment of Helicobacter pylori infection by common drugs may be associated with several problems such as antimicrobial resistance to commonly used antibiotics and side effects of employed drugs. Therefore, exploration of non-chemical compounds which are safer than chemical ones is becoming important as an alternative therapy. The purpose of this study w...

background and objectives: helicobacter pylori is the causative agent of peptic ulcer disease and a co-factor in development of gastric malignancies. lps are among toxic substances produced by h. pylori exhibiting low endotoxic activity compared to typical bacterial lps. the aim of this study was to investigate bioactivity of lps produced by different serotypes of helicobacter pylori compared t...

conclusions about 90% of h. pylori strains potentially contained vaca s2m2 and s1m2 genotypes. infection with h. pylori strain containing the caga gene or the vaca s1m1 and s1m2 genotypes was associated with increased incidence of peptic ulcer disease (pud). objectives the aim of this study was to determine the frequency of two toxins and genotypes of vaca toxin in patients referred to a centra...

OBJECTIVE To determine the association of Helicobacter pylori infection in patients presenting with idiopathic thrombocytopenic purpura (ITP). METHODS From March 2007 to March 2008, thirty adult patients with ITP and 30 age and sex matched healthy controls were investigated for the presence of H. pylori infection by Helicobacter pylori stool antigen (HpSA) an enzyme immunoassay (EIA) based me...

AIM The aim of current study is to investigate whether tonsillar and/or adenoid tissue of patients with chronic adenotonsillitis plays a reservoir role for Helicobacter pylori (H. pylori) or Helicobacter hepaticus (H. hepaticus). BACKGROUND Recently, there have been arguments ragarding Helicobacter pylori (H. pylori) being reserved in adenotonsillar tissue. PATIENTS AND METHODS This study w...

development of a stool antigen immunoassay to detect helicobacter pylori infection requires monoclonal antibody against the specific antigen. alkylhydroperoxide reductase (ahpc) of helicobacter pylori has been described as a specific and unique enzyme for h. pylori and therefore, both h. pylori ahpc and anti-ahpc could be useful in the development of serologic and stool antigen tests, for detec...

In this study, a medicinal plant, Galla rhois (GR), was examined and screened for its anti-Helicobacter pylori activity. Galla rhois was extracted with 70% ethanol. Inhibitory zone tests, as in vitro assays, and an in vivo study using a Mongolian gerbil (Meriones unguiculatus) model were performed. The safety of the GR extract was then evaluated in an animal study. The Galla rhois extract demon...

There has been a strong, positive correlation between opisthorchiasis-associated cholangiocarcinoma and infection with Helicobacter. Here a rodent model of human infection with Opisthorchis viverrini was utilized to further investigate relationships of apparent co-infections with O. viverrini and H. pylori. A total of 150 hamsters were assigned to five groups: i) Control hamsters not infected w...

Background: Resistance of Helicobacter pylori?H. pylori? to antibiotics is increasing worldwide. In order understand the current situation antibiotic resistance in Nanjing and provide a reasonable basis for clinical selection cure H. Pylori. Objective: To investigate status Pylori area, analyze primary post-treatment pylori this area. Methods: During period from July 2017 December 2019, 1533 ga...
