Characterization of a Helicobacter pylori strain with high biofilm-forming ability (2023)
Journal Article
Wilkinson, D., Alsharaf, L., Thompson, S., Paulin, A., Takor, R., Zaitoun, A., …Winter, J. (2023). Characterization of a Helicobacter pylori strain with high biofilm-forming ability. Journal of Medical Microbiology, 72(6), Article 001710. https://doi.org/10.1099/jmm.0.001710

Introduction. Helicobacter pylori is highly polymorphic, and some strains are much more likely to cause disease than others. Biofilm formation can help bacteria to survive antibiotic treatment, immune attack and other stresses, promoting persistent i...

Journal Article
Nabavi-Rad, A., Jamshidizadeh, S., Azizi, M., Yadegar, A., Robinson, K., Monaghan, T. M., & Reza Zali, M. (2023). The synergistic effect of Levilactobacillus breves IBRC-M10790 and vitamin D3 on Helicobacter pylori-induced inflammation. Frontiers in Cellular and Infection Microbiology, 13, Article 1171469

Owing to the emergence and spread of multidrug resistance mechanisms in Helicobacter pylori, achieving a successful eradication has become exceedingly difficult. Thus, this study for the first time determines the effect of a combination of vitamin D3...

The active form of Helicobacter pylori vacuolating cytotoxin induces decay-accelerating factor CD55 in association with intestinal metaplasia in the human gastric mucosa (2022)
Journal Article
Kaneko, K., Zaitoun, A. M., Letley, D. P., Rhead, J. L., Torres, J., Spendlove, I., …Robinson, K. (2022). The active form of Helicobacter pylori vacuolating cytotoxin induces decay-accelerating factor CD55 in association with intestinal metaplasia in the human gastric mucosa. Journal of Pathology, https://doi.org/10.1002/path.5990

High-level expression of decay-accelerating factor, CD55, has previously been found in human gastric cancer (GC) and intestinal metaplasia (IM) tissues. Therapeutic effects of CD55 inhibition in cancer have been reported. However, the role of Helicob...

There is no consensus among the existing literature on the relationship between ABO blood groups and risk of Helicobacter pylori infection. However, histo-blood group carbohydrates are proposed to influence the risk of acquiring this pathogen via eff...

Association between infection with H. pylori and atopy in young Ethiopian children: a longitudinal study (2017)
Journal Article
Taye, B., Enquselassie, F., Tsegaye, A., Amberbir, A., Medhin, G., Fogarty, A. W., …Davey, G. (in press). Association between infection with H. pylori and atopy in young Ethiopian children: a longitudinal study. Clinical and Experimental Allergy, 47(10), https://doi.org/10.1111/cea.12995

Background: Epidemiological evidence from developed countries indicates that Helicobacter pylori infection correlates with a reduced risk of atopy and allergic disorders, however limited data are available from low-income countries. Objective: We... Read More about Association between infection with H. pylori and atopy in young Ethiopian children: a longitudinal study.

Effect of Helicobacter pylori infection on growth trajectories in young Ethiopian children: a longitudinal study (2016)
Journal Article

International Journal of Infectious Diseases, 50, 57-66. https://doi.org/10.1016/j.ijid.2016.08.005

Background Helicobacter pylori infection has been associated with early childhood growth impairment in high- and middle-income countries; however, few studies have examined this relationship within low-income countries or have used a longitudinal de...

Expression of the Helicobacter pylori virulence factor vacuolating cytotoxin A (vacA) is influenced by a potential stem-loop structure in the 5' untranslated region of the transcript (2015)
Journal Article

The vacuolating cytotoxin, VacA, is an important virulence factor secreted by the gastric pathogen Helicobacter pylori. Certain vacA genotypes are strongly associated with disease risk, but the association is not absolute. The factors determining vac...
