Campylobacter concisus Genomospecies 2 Is Better Adapted to the Human Gastrointestinal Tract as Compared with Campylobacter concisus Genomospecies 1
Campylobacter concisus was previously shown to be associated with inflammatory bowel disease including Crohn's disease (CD) and ulcerative colitis (UC). C. concisus has two genomospecies (GS). This study systematically examined the colonization of GS1 and GS2 C. concisus in the human gastrointestinal tract. GS1 and GS2 specific polymorphisms in 23S rRNA gene were identified by comparison of the...
متن کاملNeutrophil activation by Campylobacter concisus
BACKGROUND Campylobacter concisus is an emerging enteric pathogen associated with prolonged diarrhoea and possibly inflammatory bowel disease in children as well as adults, but the interaction with cells of the innate immune system is unclear. The magnitude of systemic immunoglobulin response in acute infection is unknown. METHODS Neutrophils from healthy volunteers were activated with five f...
متن کاملLectin typing of Campylobacter concisus.
A total of 44 clinical isolates and the type strain of the putative pathogen Campylobacter concisus were grouped based on their reactions with plant lectins. The optimized lectin typing system used C. concisus strains proteolytically pretreated and subsequently typed by using a panel of four lectins. The system grouped all 45 strains into 13 lectin reaction patterns, leaving no strain untypeabl...
متن کاملOptimization of Plasma Sample Pretreatment for Quantitative Analysis Using iTRAQ Labeling and LC-MALDI-TOF/TOF
Shotgun proteomic methods involving iTRAQ (isobaric tags for relative and absolute quantitation) peptide labeling facilitate quantitative analyses of proteomes and searches for useful biomarkers. However, the plasma proteome's complexity and the highly dynamic plasma protein concentration range limit the ability of conventional approaches to analyze and identify a large number of proteins, incl...
متن کاملDossier MALDI - TOF ■ Oligonucleotide analysis by MALDI - MS
Matrix-assisted laser desorption (MALDI) time-offlight (TOF) mass spectrometry (MS) has been successfully used for oligonucleotide sequence confirmation by mass analysis of fragments generated by concentration-dependent exonuclease digestion. This approach is particularly well-suited to the analysis of synthetic DNA due to the relatively short length of the DNA strands. Additionally, an importa...
