Binding 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 کاملCharacterization of Haemophilus influenzae type b fimbriae.
We confirmed that the fimbriae of Haemophilus influenzae type b conferred hemagglutinating activity (HA) towards human erythrocytes, and erythrocytes of certain other species. Most (17/25) cerebrospinal fluid isolates lacked detectable HA on direct testing, but selective enrichment for fimbriation (f+) indicated that 22 of 25 strains could produce these surface structures. HA was unchanged from...
متن کاملMolecular 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 کاملSialic acid and N-acetylglucosamine Regulate type 1 Fimbriae Synthesis.
Type 1 fimbriae of E. coli, a chaperon-usher bacterial adhesin, are synthesized by the majority of strains of the bacterium. Although frequently produced by commensal strains, the adhesin is nevertheless a virulence factor in Extraintestinal Pathogenic E. coli (ExPEC). The role of the adhesin in pathogenesis is best understood in Uropathogenic E. coli (UPEC). Host attachment and invasion by typ...
