T2182C Mutation Is Not Associated with Clarithromycin Resistance in Helicobacter pyloriIn a recent article, Khan et al. described a new mutation in the 23S rRNA gene, T2182C, conferring clarithromycin resistance to Helicobacter pylori (1).An A-to-G mutation at either position 2142 or position 2143 a...

BACKGROUND: Salmonella enterica serovar Enteritidis is a cause of both poultry- and egg-associated enterocolitis globally and bloodstream-invasive nontyphoidal Salmonella (iNTS) disease in sub-Saharan Africa (sSA). Distinct, multi-drug resistant genotypes associated with iNTS disease in sSA have rec...

Laboratory case definition of leptospirosis is scarcely defined by a solid evaluation that determines cut-off values in the tests that are applied. This study describes the process of determining optimal cut-off titers of laboratory tests for leptospirosis for a valid case definition of leptospirosi...

Data from the Quality Assurance System in Danish Broiler Production (KIK system) were analyzed to identify within farm biosecurity- and management-related risk factors for Campylobacter infection in Danish broiler flocks. In the study, data from 2,835 flocks originating from 187 farms in the time pe...

Helicobacter pylori is a genetically diverse bacterial species, which has facilitated adaptation to new hosts and persists worldwide. The main objective of this study was to explore intra-familial transmission of H. pylori in Bangladesh. We characterized H. pylori in 35 families including 138 family...

Virulence-associated genes and neutral DNA markers of Helicobacter pylori strains from the Santhal and Oroan ethnic minorities of West Bengal, India, were studied. These people have traditionally been quite separate from other Indians and differ culturally, genetically, and linguistically from mains...

The complex relation between the genotype of Helicobacter pylori and its association with clinical outcome is not well understood. Studies in the West have showed that strains expressing certain virulence factors (vacAs1, vacAm1, and cagA) are associated with duodenal ulcer disease. However, the H. ...

Little is known about clinical and epidemiological features of Plesiomonas shigelloides-associated diarrhoea in children. We reviewed hospital-based surveillance records of 38 children with diarrhoea having P. shigelloides as the only pathogen isolated from their faecal specimen. Of those 38 childre...

In healthy controls (n = 8) living in shigella endemic areas, accumulation of interferon gamma (IFN gamma) in the epithelial lining was seen in the rectal tissues. At the single cell level, however, few or no IFN gamma protein producing cells or mRNA expressing cells were detected at that site indic...

A method for detecting Entamoeba histolytica trophozoite antigens in aqueous solution is described. This involves coating plastic microtitre plates with a 'catching antibody', specific rabbit anti-E. histolytica antibody (SRAE). After adding the test material the presence of antigen is determined us...

Helicobacter pylori is an important cause of chronic gastritis leading to peptic ulcer and is a major risk factor for gastric malignancies. Failure in the eradication of H. pylori infection and increasing antibiotic resistance are two major problems in preventing H. pylori colonization. Hence, a dee...

The diphtheria outbreak in the Rohingya refugee population in Bangladesh, the outbreak in Yemen due to war, and the more recent outbreaks in Venezuela and Haiti should raise concern that diphtheria remains a public health issue in 2017/2018, almost a century after an effective and safe toxoid vaccin...

The Toll-like receptor (TLR)4 is critical for the recognition of Gram-negative bacterial lipopolysaccharide (LPS) but in porcine peripheral blood mononuclear cells (PBMCs) it may cooperate with other TLRs and lead to the production of inflammatory cytokines. Therefore, we analyzed TLR1–10 mRNA expre...

BACKGROUND: Tetanus is a severe disease that can be prevented by vaccination. In developing countries vaccination coverage is not always high. Cases still occur also in developed countries, particularly in elderly people owing to their reduced immuno protection. There are about 1 million tetanus cas...

A polymerase chain reaction (PCR) assay, based on the amplification of a species specific ureA (urease) gene internal sequence, was used to detect Helicobacter pylori . Total DNA extracts were obtained from dental plaque in patients attending an endoscopy clinic and from apparently healthy schoolchi...
