The possible functions of two recently described flagellar genes, fliU and fliV, have been examined. Introduction of gene fliC, encoding the bacterial flagellin protein, into a number of flagellin-deficient Salmonella and Escherichia coli strains failed to complement the mutations in these strains, and the FliC flagellin was accumulated in the bacterial cytoplasm. Complementation with fliU and ...

A newly developed PCR-based assay for the H7 variant of the Escherichia coli flagellin gene, fliC, was 100% sensitive and specific in comparison with serology and probe hybridization. It revealed broad conservation of the H7 fliC variant among phylogenetically diverse lineages of extraintestinal pathogenic E. coli (ExPEC) and superseded serotyping for certain isolates with ambiguous or non-H7 s...

BACKGROUND Salmonella spp. is the major bacterial pathogen in poultry and is responsible for significant economic losses of the poultry industry in many parts of the world. Among Salmonella spp., Salmonella gallinarum and Salmonella. pullorum are the most common causative agents of chicken salmonellosis resulting in high mortality and morbidity. OBJECTIVES The aim of this study was to identif...

U pałeczek Salmonella obserwuje się więcej niż jedną fazę antygenów rzęskowych, co jest uwarunkowane występowaniem jednego, dwóch lub trzech genów, które niezależnie od siebie kodują białko strukturalne witki rzęski o właściwościach antygenowych. Gen fliC koduje antygen rzęskowy pierwszej fazy, natomiast gen fljB – drugiej fazy. Trzecia faza antygenu rzęskowego związana jest z genem umiejscowio...

Flagellums have been reported to play a critical role in the protective immunity in host. In clostridia genera it is coded by flagellin (fliC) gene. Previous southern blot analysis has suggested that Flic gene may has two copies in genome of C. chauvoei. We studied sequences of two copies (fliA and fliB) of flagellin gene in Iranian isolates. In this study, four specific primers for fliA, fliB ...

In this study, we performed fliC PCR-restriction fragment length polymorphism (RFLP) to investigate whether this technique would be better than classic serotyping for the characterization of the H antigen in enterotoxigenic Escherichia coli (ETEC) strains. We showed that the fliC genes from ETEC strains can be characterized by restriction analysis of their polymorphism. Only one allele of the f...

OBJECTIVES To assess patients with recurrent high grade brain glioma with the aim of evaluating facets of quality of life (QOL) and their association with mood, cognition, and physical performance. METHODS Ninety four glioma patients (four groups with different duration of glioma recurrence) were compared with 24 patients with other chronic neurological diseases and 48 healthy subjects. The F...
