Characterization of type 1 and mannose-resistant fimbriae of Erwinia spp.
نویسندگان
چکیده
Type 1 fimbriae from Erwinia carotovora subsp. carotovora and mannose-resistant fimbriae from Erwinia rhapontici were purified and characterized. The type 1 fimbrillin had an apparent molecular weight of 16,500; that of the mannose-resistant fimbrillin was 18,000. The amino-terminal amino acid sequences of the two fimbrillins were related, but tryptic peptide maps showed significant differences between the proteins. No serological cross-reaction was found between the two fimbrial filaments, nor did they cross-react with type 1 or type 3 fimbriae purified from other enterobacterial species. Immunofluorescent staining of bacterial populations revealed that they were heterogeneous with respect to fimbriation.

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...

In order to study the relationship between hrmolysin / ashesins of Escherichia coli and occurrence of urinary tract infection ( UTI), the capacity of 570 isolated E.coli in agglutination of human or guinea pig erythrocytes and their lysis were tested. These isolates were obtained from the urine of patients with bacteriuria and from the stool of healthy people. Three patterns of hemagglutinat...

The uropathogenic Escherichia coli strain 536 (O6:K15:H31) exhibits a mannose-resistant hemagglutination phenotype (Mrh) with bovine erythrocytes and delayed Mrh with human and guinea pig erythrocytes. Neuraminidase treatment of the erythrocytes abolishes mannose resistant hemagglutination, which is typical for X fimbriae. E. coli strain 536 synthesizes two different fimbriae (Fim phenotype) pr...

Fimbriae from three Escherichia coli strains, C1212, C1214, and C1023, isolated from urinary tract infections, have been purified and characterized by determination of the N-terminal sequences, amino acid composition, and molecular weights of their respective subunits. Furthermore, their immunological interrelationships have been investigated. The three strains all harbored more than one fimbri...

This study documents the presence of type 1 fimbriae on Shigella and confirms these mannose-sensitive adherence structures to be bona fide components of the Shigella surface. While laboratory-passaged Shigella strains and lyophilized clinical isolates failed to express type 1 fimbriae, 6 of 20 recent clinical isolates, including 4 Shigella flexneri strains, 1 Shigella boydii strain, and 1 Shige...
