Abstract Helicobacter pylori , a dominant member of the gastric microbiota, shares co-evolutionary history with humans. This has led to development genetically distinct H. subpopulations associated geographic origin host and differential disease risk. Here, we provide insights into population structure as part Genome Project ( Hp GP), multi-disciplinary initiative aimed at elucidating pathogenesis identifying new therapeutic targets. We collected 1011 well-characterized clinical strains from...
We report 4 children with encephalitis associated human bocavirus (HBoV) 1 or 2. All were severely underweight, and 2 died; of them had a matching HBoV2 nucleotide sequence isolated from serum like particles in the cerebrospinal fluid that observed electron microscopy. No further pathogens detected these patients.
Helicobacter pylori (H. pylori) related chronic gastritis is a well-known major etiological factor for gastric cancer development. However, H. pylori-negative (HpN) not well described. We aimed to examine mucosal microbiota in HpN compared pylori-positive (HpP) and non-gastritis group (control). Here, we studied 11 subjects with HpN, 40 HpP 24 controls. performed endoscopy six biopsies. Comparison groups were defined based on strict histological criteria the disease diagnosis. used 16S rRNA...
Current management of gastric inflammation involves the eradication Helicobacter pylori. However, effectiveness commonly used antibiotics against H. pylori infection has decreased due to antibiotic resistance. Phenotypic-based diagnostics are laborious and finding cause resistance can be difficult. Therefore, early detection understanding underlying mechanism this necessary. This study evaluated mutations in genes related Antimicrobial Resistance (AMR) clinical isolates from Bangladeshi...
The number of copies rRNA (rrn) operons in a bacterial genome differs greatly among species. Here we examined the phenotypic effects variations genes Bacillus subtilis by analysis eight mutant strains constructed to carry from two nine rrn operon. We found that decrease ten one increased doubling time, and decreased sporulation frequency motility. maximum levels for transformation activity were similar strains, although competence development was significantly delayed strain with single...
We evaluated biofilm formation of clinical Helicobacter pylori isolates from Indonesia and its relation to antibiotic resistance. determined the minimum inhibition concentration (MIC) amoxicillin, clarithromycin, levofloxacin, metronidazole tetracycline by Etest measure planktonic susceptibility 101 H. strains. Biofilms were quantified crystal violet method. The eradication (MBEC) was obtained measuring survival bacteria in a after exposure antibiotics. majority strains formed (93.1%...
Antimicrobial susceptibility testing (AST) is increasingly needed to guide the Helicobacter pylori (H. pylori) treatment but remains laborious and unavailable in most African countries. To assess clinical relevance of bacterial whole genome sequencing (WGS)-based methods for predicting drug H. pylori, 102 strains isolated from Democratic Republic Congo were subjected phenotypic AST next-generation (NGS). WGS was used screen occurrence genotypes encoding antimicrobial resistance (AMR). We...
Helicobacter pylori (H. pylori) has been identified as a type I carcinogen and contributes to high rate of gastric cancer (GC), especially in Eastern Asia.
