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 کاملAdhesion of piliated Escherichia coli strains to phagocytes: differences between bacteria with mannose-sensitive pili and those with mannose-resistant pili.
Escherichia coli with mannose-resistant (MR) pili, in contrast to those with mannose-sensitive (MS) pili, did not adhere to rat peritoneal macrophages and human polymorphonuclear granulocytes, as measured by use of radioactive bacteria and by the chemiluminescence response induced by the cell contact. With some MS-piliated E. coli strains, unpiliated bacteria, obtained by growth at a pilus-rest...
متن کاملMannose-sensitive and Gal-Gal binding Escherichia coli pili from recombinant strains. Chemical, functional, and serological properties
Chromosomal genes encoding the MS and Gal-Gal binding properties have been cloned into separate recombinants and their respective pili characterized. Hapten inhibition of hemagglutination with synthetic carbohydrate receptor analogues and carbohydrate-adsorbed latex agglutination studies indicate that Gal-Gal and MS pili collectively exhibit the binding properties of the parent strain. MS pili ...

objective: aminoglycosides are highly potent, broad-spectrum antibiotics with many desirable properties for the treatment of life-threatening infections. escherichia coli (e. coli) is the most common cause of urinary tract infection (uti). antibiotic resistance has recently become prevalent. enzymatic inactivation of aminoglycosides by aminoglycoside-modifying enzymes is the main mechanism of r...
متن کاملBinding specificity of piliated strains of Escherichia coli and Salmonella typhimurium to epithelial cells, saccharomyces cerevisiae cells, and erythrocytes.
The binding to mammalian cells of piliated enteric bacteria and the inhibition of the binding by antibodies to purified pili were studied. The target cells were epithelial cells from human bucca and human and rat urinary tracts, erythrocytes from various species, and Saccharomyces cerevisiae cells. The strains were selected to represent the two main agglutination patterns of enteric bacteria: m...
