Arcobacter (A.) butzleri has been described as causative agent for sporadic cases of human gastroenteritis with abdominal pain and acute or prolonged watery diarrhea. In vitro studies ...
To assess the prevalence of gastrointestinal neoplasia in patients with Streptococcus bovis infectious endocarditis we performed a retrospective cohort analysis of all episodes of S. bovis infectious endocarditis...
It remains unclear whether the low incidence of gastric cancer in Indonesia is due to low infection rates only or is also related to low Helicobacter pylori pathogenicity. We collected H. pylori strains from the ...
Developmentally early cells are mobilized into peripheral blood in Crohn’s disease (CD) patients. OCT4, is considered to be important in sustaining the pluripotency of stem cells. OCT4 splicing variants are diffe...
Salmonella enterica serovar Enteritidis, the most common cause of human gastroenteritis, employs several virulence factors including lipopolysaccharide (LPS) for infection and establis...
Dietary zinc oxide is used in pig nutrition to combat post weaning diarrhoea. Recent data suggests that high doses (2.5 g/kg feed) increase the bacterial antibiotic resistance development in weaned pigs. There...
Previous studies have highlighted the antimicrobial activity of caffeine, both individually and in combination with other compounds. A proposed mechanism for caffeine’s antimicrobial effects is inhibition of b...
Clinical and preclinical observations indicate that Lactobacillus plantarum has anti-inflammatory activity and may regulate the immune responses of its hosts when ingested. Recently, modification of teichoic acid...
Recently the Type VI secretion system (T6SS), which can play a significant role in bacterial survival and pathogenesis, was reported in Campylobacter spp., having the hcp gene as a key component.
For many putative Salmonella enterica subsp. enterica virulence genes, functional characterization across serovars has been limited. Cytolethal distending toxin B (CdtB) is an incompletely characterized virulence...
The O48 group comprises Salmonella bacteria containing sialic acid in the lipopolysaccharide (LPS). Bacteria with sialylated surface structures are described as pathogens that avoid immunological response of the ...
A recent report on the detection in a Crohn’s disease (CD) patient of an adherent and invasive Shiga toxin producing Escherichia coli (STEC) (Gut pathogens 2015, 7:2) prompted a commentary expressing some skeptic...
