The gastric mucosa of dogs is often colonized by non-Helicobacter pylori helicobacters (NHPH), while H. pylori is the predominant gastric Helicobacter species in humans. The colonization of the human stomach by H. pylori is highly dependent on the recognition of host glycan receptors. Our goal was to define the canine gastric mucosa glycophenotype, to evaluate the capacity of different gastric ...

Helicobacter pylori is a Gram-negative bacterium that is considered a causative agent of peptic ulcer disease, gastric lymphoma, and gastric carcinoma. Helicobacter pylori triggers an intense leucocyte infiltration of the gastric submucosa, an action which is mediated by pro-inflammatory cytokines. This pathogenetic mechanism is common to many other diseases and consequently, Helicobacter pylor...

Patients of chronic gastritis should be investigated with gastric mucosal biopsy, parietal cell antibody, intrinsic factor antibody, Helicobacter pylori antibody, urea breath test or faecal antigen test for Helicobacter pylori, to accurately classify them. The results of these tests will indicate Helicobacter pylori infection (present or past), the role of hereditary factor (intrinsic factor an...

BACKGROUND AND AIM We present a new clinical entity in relation to the Helicobacter pylori infection characterized by complex and varied clinical extra-digestive manifestations. Clinical findings such as asthenia, adynamia, sleep disorders, hair and nails modifications, digestive symptoms and heart rhythm disorders describe the clinical aspect of toxicosis associated with Helicobacter pylori in...

Introduction: Helicobacter pylori infection is associated with a wide range of digestive diseases and is very prevalent in developing countries, although few data exist on the susceptibility of helicobacter pylori to antimicrobial agents. The aim of this study was to determine the susceptibility patterns in helicobacter pylori strains isolated from patients in Kermanshah to twelve antimicrobial...

The aim of this study was to explore the prevalence of Helicobacter pylori infection in different surgical diseases in patients with six different cancer types. We analyzed sixty consecutive patients with malignancy (gastric cancer, pancreatic cancer, hepatocellular cancer, intestinal cancer, colon cancer, rectal cancer). Detection of specific IgA and IgG antibodies to Helicobacter pylori in hu...

There is increasing evidence that certain microbial agents may have an etiopathogenic role in the development of atherothrombosis. Helicobacter pylori, a bacterium that causes peptic ulcer disease, has been suggested as one of the microbes involved in the development of atherothrombosis. This hypothesis is based on the following observations: a) a higher prevalence of Helicobacter pylori infect...

An unusual Helicobacter sp. was isolated from the blood of a human immunodeficiency virus (HIV)-infected patient. This organism had spiral morphology, with single amphitrichous flagella, and was negative for hippurate hydrolysis, production of urease, and reduction of nitrate. 16S rRNA gene sequence analysis verified that the isolate was a species of Helicobacter, most closely related to an und...

Gastric biopsies are often done to evaluate for Helicobacter gastritis. Given the oncogenic association with Helicobacter gastritis and the relative ease of therapy, it is important for pathology departments to identify all positive cases. We describe an institutional quality assurance study of an institutional method for the diagnosis of Helicobacter gastritis. We reviewed 356 gastric biopsy s...

The presence of Helicobacter species in Australian marsupials was examined systematically using microscopy, culture, and PCR in different regions of the gastrointestinal tract (GIT) and in the liver of brushtail possums (BTPs) (Trichosurus vulpecula), a common Australian marsupial that feeds on eucalyptus leaves. The spatial distribution of Helicobacter species in the GIT sections also was exam...
