The role of mannose sensitive and mannose resistant pili of Escherichia coli in urinary tract infection
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...
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 کاملthe study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media
امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Characterization of type 1 and mannose-resistant fimbriae of Erwinia spp.
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...
متن کاملIn vivo expression of the mannose-resistant fimbriae of Photorhabdus temperata K122 during insect infection.
Photorhabdus temperata K122 is an entomopathogenic bacterium symbiotically associated with nematodes of the family Heterorhabditidae: Surface fimbriae are important for the colonization of many pathogenic bacteria, and here we report the nucleotide sequence and analysis of the expression of a 12-kbp fragment encoding the mannose-resistant fimbriae of P. temperata (mrf). The mrf gene cluster con...
