Clostridium difficile is the main agent responsible for hospital acquired antibiotic associated diarrhoea. In recent years, epidemic strains have emerged causing more severe infections. Whilst C. difficile has two major virulence factors, toxins TcdA and TcdB, it is generally accepted that other virulence components of the bacterium contribute to disease. Previously, it has been suggested that ...
Edwardsiella tarda is a flagellated gram-negative bacterium which causes edwardsiellosis in fish. FliC, as a flagellar filament structural protein, is hypothesized to be involved in the pathogenesis of infection. In this study, a fliC in-frame deletion mutant of a virulent isolate of E. tarda was constructed through double crossover allelic exchange by means of the suicide vector pRE112, and it...
conclusions the r-b-flagellin carried antigenic epitopes just like the native flagellin, while the polyclonal antibody raised against it exhibited functional activity. results the polyclonal antibodies raised against this r-b-flagellin inhibited the motility of the homologous pao1 strain of p. aeruginosa, which significantly decreased the invasion of the pao1 strain into the a549 cells and also...
The E. coli flagellar types H1 and H12 show a high serological cross-reactivity and molecular serotyping appears an advantageous method to establish a clear discrimination between these flagellar types. Analysis of fliC H1 and fliC H12 gene sequences showed that they were 97.5% identical at the nucleotide level. Because of this high degree of homology we developed a two-step real-time PCR detec...
Uropathogenic Escherichia coli (UPEC) is the cause of ~75% of all urinary tract infections (UTIs) and is increasingly associated with multidrug resistance. This includes UPEC strains from the recently emerged and globally disseminated sequence type 131 (ST131), which is now the dominant fluoroquinolone-resistant UPEC clone worldwide. Most ST131 strains are motile and produce H4-type flagella. H...
Abstract Background In inflammatory bowel disease (IBD), including Crohn’s (CD) and ulcerative colitis (UC), CD4+ T cell-responses to unknown microbial antigens drive intestinal inflammation. Both hypo- or hyperactive anti-microbial innate immunity may underlie these pathogenic T-cell responses. Previously, IgG responses Lachnospiraceae flagellins were detected in spontaneously colitic mice wit...
