Molecular Study of Phase Variation of Type 1 Fimbriae in Uropathogenic Escherichia coli O44 Serotypes during Touching with Solid Surfaces
Background & Aims: Type 1 fimbriae is the most common adhesion factor in urine tract infection. In this Study, presence of virulence genes in isolated strains of uropathogenic E.Coli, O serotyping and molecular detection of phase variation of type 1 fimbriae were assessed during solid surfaces exposure. Methods: Isolated E.coli from urine samples of patients were serotyped by using serologic me...
متن کاملAntigen 43 and type 1 fimbriae determine colony morphology of Escherichia coli K-12.
Colony morphology has been used as an important identification and characterization criterion in bacteriology for many decades. However, the molecular mechanisms underlying the appearance of different colony types have been given little attention. The synthesis of O antigen is defunct in Escherichia coli K-12, and colonies should accordingly only appear to be rough. However, previous reports ha...
متن کاملBinding of nonspecific cross-reacting antigen, a granulocyte membrane glycoprotein, to Escherichia coli expressing type 1 fimbriae.
Nonspecific cross-reacting antigen (NCA) is a well-characterized membrane glycoprotein on granulocytes, macrophages, and lung epithelium. Structural studies at the protein and genomic levels have revealed that NCA is a member of the immunoglobulin supergene family, and hybridization studies showed that the transcript level of NCA is induced by treatment with gamma interferon. These studies, as ...
متن کاملAdaptive mutations in the signal peptide of the type 1 fimbrial adhesin of uropathogenic Escherichia coli.
Signal peptides (SPs) are critical for protein transport across cellular membranes, have a highly conserved structure, and are cleaved from the mature protein upon translocation. Here, we report that naturally occurring mutations in the SP of the adhesive, tip-associated subunit of type 1 fimbriae (FimH) are positively selected in uropathogenic Escherichia coli. On the one hand, these mutations...
متن کاملcomplex interplay between type 1 fimbrial expression and flagellum-mediated motility of uropathogenic Escherichia coli.
Type 1 fimbriae and flagella have been previously shown to contribute to the virulence of uropathogenic Escherichia coli (UPEC) within the urinary tract. In this study, the relationship between motility and type 1 fimbrial expression was tested for UPEC strain CFT073 by examining the phenotypic effect of fimbrial expression on motility and the effect that induction of motility has on type 1 fim...
