Structure of the Helicobacter pylori Cag type IV secretion system.
Chung JM, et al. Elife 2019. PMID 31210639 Free PMC article.
The Helicobacter pylori Cag T4SS translocates CagA, a bacterial oncoprotein, into gastric cells, contributing to gastric cancer pathogenesis. ...

Biochemical characterization of the Helicobacter pylori bactofilin-homolog HP1542.
Holtrup S, et al. PLoS One 2019. PMID 31233532 Free PMC article.
The human pathogen Helicobacter pylori is known for its colonization of the upper digestive system, where it escapes the harsh acidic environment by hiding in the mucus layer. ...Interestingly our results indicate that H. pylori bactofilin does not contribute to cell wall stability. This study might act as a starting point for biophysical studies of the H. pylori bactofilin biology as well as for the investigation of bactofilin cell physiology in this organism. ...

Measurement of Internal pH in Helicobacter pylori by Using Green Fluorescent Protein Fluorimetry.
Wen Y, et al. J Bacteriol 2018. PMID 29735759 Free PMC article.
Helicobacter pylori is an organism known to colonize the normal human stomach. Previous studies have shown that the bacterium does this by elevating its periplasmic pH via the hydrolysis of urea. ...To measure the periplasmic pH directly in H. pylori, we fused enhanced green fluorescent protein (EGFP) to the predicted twin-arginine signal peptides of HydA and KapA from H. pylori and TorA from Escherichia coli The fusion proteins were expressed in the H. pylori genome under the control of the cagA promoter. ...

Accuracy of urea breath test in Helicobacter pylori infection: meta-analysis.
Ferwana M, et al. World J Gastroenterol 2015 - Review. PMID 25632206 Free PMC article.
AIM: To quantitatively summarize and appraise the available evidence of urea breath test (UBT) use to diagnose Helicobacter pylori (H. pylori) infection in patients with dyspepsia and provide pooled diagnostic accuracy measures. METHODS: We searched MEDLINE, EMBASE, Cochrane library and other databases for studies addressing the value of UBT in the diagnosis of H. pylori infection. ...

In Vivo Structures of the Helicobacter pylori cag Type IV Secretion System.
Chang YW, et al. Cell Rep 2018. PMID 29669273 Free PMC article.
Here, using electron cryotomography, we reveal the molecular architecture of the Helicobacter pylori cag T4SS. Although most components are unique to H. pylori, the cag T4SS exhibits remarkable architectural similarity to other T4SSs. Our images revealed that, when H. pylori encounters host cells, the bacterium elaborates membranous tubes perforated by lateral ports. ...

Advances in diagnosis and treatment of Helicobacter pylori infection.
Ranjbar R, et al. Acta Microbiol Immunol Hung 2017 - Review. PMID 28263101
Helicobacter pylori is a Gram-negative motile bacterium causative agent of acute and chronic digestive and extra-digestive human infections. ...Furthermore, there are several pharmacotherapies which can be used for complete eradication of H. pylori infection....

Biochemical and Biophysical Characterization of the Enolase from Helicobacter pylori.
López-López MJ, et al. Biomed Res Int 2018. PMID 30648111 Free PMC article.
Helicobacter pylori is a common human pathogen that causes gastric diseases and even gastric cancer. In this study, the sequence of H. pylori enolase (HpEno) was analysed; the conservation (at least partial) of binding sites for cofactor, plasminogen, and host extracellular RNA, as well as catalytic site, indicates that HpEno should be capable of performing the functions. ...

Helicobacter pylori does not use spermidine synthase to produce spermidine.
Zhang H and Au SWN. Biochem Biophys Res Commun 2017. PMID 28648602
Helicobacter pylori is the primary pathogen associated to gastritis and gastric cancer. Growth of H. pylori depends on the availability of spermidine in vivo. Interestingly, the genome of H. pylori contains an incomplete set of genes for the classical pathway of spermidine biosynthesis. ...

Structural Analysis of Glutamine Synthetase from Helicobacter pylori.
Joo HK, et al. Sci Rep 2018. PMID 30076387 Free PMC article.
Glutamine synthetase (GS) is an enzyme that regulates nitrogen metabolism and synthesizes glutamine via glutamate, ATP, and ammonia. ...GS is an essential protein for the survival of Helicobacter pylori which its infection could promote gastroduodenal diseases. ...

Feco-prevalence and risk factors of Helicobacter pylori infection among symptomatic patients at Dessie Referral Hospital, Ethiopia.
Seid A and Demsiss W. BMC Infect Dis 2018. PMID 29879914 Free PMC article.
BACKGROUND: Helicobacter pylori (H. pylori) infection is the most common chronic bacterial infection in the world. It can result in various upper gastroduodenal diseases. ...Stool samples were used to detect H. pylori specific antigen. Blood samples were assessed for anti-H. pylori IgG and ABO blood types. ...
