Helicobacter pylori Infection, Chronic Inflammation, and Genomic Transformations in Gastric MALT Lymphoma

Mediators of Inflammation, Volume 2013, Issue 1, 2013., 2013
Nowadays, it is believed that the main role in the development of gastric mucosa‐associated lymphoid tissue (MALT) lymphoma plays Helicobacter pylori infection. This world‐wide distributed bacteria is in charge of most cases of not only upper gastrointestinal tract disorders but also some of extragastric problems.

Clinical Management of Helicobacter Infection in Captive Baboons (Papio anubis and Papio hamadryas), and Isolation and Molecular Characterization of Three Novel Helicobacter Species

Journal of Medical Primatology, Volume 55, Issue 4, August 2026.
ABSTRACT Background Helicobacter spp. are gastric or enterohepatic bacteria that can be commensal, opportunistic, or pathogenic. Few studies have evaluated Helicobacter spp. in baboons. Methods Twenty‐seven captive baboons were surveyed for Helicobacter spp. by fecal PCR, and a subset evaluated by culture.

Comparing Multiplex PCR and Rapid Urease Test in the Detection of H. pylori in Patients on Proton Pump Inhibitors

Gastroenterology Research and Practice, Volume 2012, Issue 1, 2012., 2012
Background. This study was conducted to assess the diagnostic value of a multiplex PCR assay to detect H. pylori infection and to further evaluate the negative results from the CLOtest on patients with and without PPI treatment. Methods. This study is a retrospective cohort that included 457 patients with symptoms of dyspepsia, who underwent upper ...

Endoscopic features differentiating non‐Helicobacter pylori Helicobacter‐induced gastric mucosa‐associated lymphoid tissue lymphoma with a nodular gastritis‐like appearance and H. pylori‐induced conventional nodular gastritis

Digestive Endoscopy, Volume 37, Issue 9, Page 998-1009, September 2025.
Objectives Conventional nodular gastritis has been known to be caused by Helicobacter pylori infection. Several cases of gastric mucosa‐associated lymphoid tissue (MALT) lymphoma with non‐H. pylori Helicobacters (NHPH) exhibit endoscopic findings resembling nodular gastritis.

Molecular Characterization of the 16S rRNA Gene of Helicobacter fennelliae Isolated from Stools and Blood Cultures from Paediatric Patients in South Africa

Journal of Pathogens, Volume 2011, Issue 1, 2011., 2011
Forty strains of H. fennelliae collected from paediatric blood and stool samples over an 18 year period at a children′s hospital in Cape Town, South Africa, were amplified by PCR of the 16S rRNA. Two distinct genotypes of H. fennelliae were identified based on the phylogenetic analysis.

Comparative Genomics of Helicobacter pylori and the human-derived Helicobacter bizzozeronii CIII-1 strain reveal the molecular basis of the zoonotic nature of non-pylori gastric Helicobacter infections in humans

BMC Genomics, 2011
Background The canine Gram-negative Helicobacter bizzozeronii is one of seven species in Helicobacter heilmannii sensu lato that are detected in 0.17-2.3% of the gastric biopsies of human patients with gastric symptoms. At the present, H. bizzozeronii is

Antimicrobial Susceptibility Pattern of Helicobacter heilmannii and Helicobacter ailurogastricus Isolates

Microorganisms, 2020
A combined agar and broth dilution method followed by qPCR was used to determine the antimicrobial susceptibility of feline H. heilmannii and H. ailurogastricus isolates. All H. ailurogastricus isolates showed a monomodal distribution of MICs for all the

A Three‐Way Comparison of Nodular Lesions in H. pylori‐Induced Gastritis, Non‐Helicobacter pylori Helicobacter (NHPH)‐Induced Gastritis, and NHPH‐Induced MALT Lymphoma Reveals Their Distinct Endoscopic Predictors: Distribution for Bacterial Etiology and Morphology for Malignancy

Helicobacter, Volume 30, Issue 5, September/October 2025.
ABSTRACT Background Nodular gastritis associated with Helicobacter pylori infection (HPi‐NG) has long been recognized. Recently, similar mucosal changes have been reported with non‐H. pylori Helicobacter (NHPH), including NHPH‐induced gastric mucosa‐associated lymphoid tissue lymphoma with a nodular gastritis‐like appearance (NHPHi‐MNG) and NHPH ...

Ultrastructural and molecular characterization of non-Helicobacter pylori species in the gastric mucosa of naturally infected pigs

Brazilian Journal of Veterinary Pathology, 2018
Infection by Helicobacter spp. has been associated with gastritis and ulcers in pigs and humans. Association between Helicobacter species and lesions can contribute to determine specific pathogenicity.

Wildlife Pathogens and Zoonotic Disease Risk Assessment in Vietnam: A Wildlife Trade Hotspot

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Vietnam is a wildlife trade hotspot presenting multiple high‐risk interfaces for pathogen spillover from wildlife to humans. However, the zoonotic disease risk remains poorly characterized in the country and needs to be assessed to better inform policy dialog and legislative reforms.
