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 Escherichia coli to human uroepithelial cells in vitro.
Optimal conditions for in vitro adherence of Escherichia coli to uroepithelial cells, previously shown to more efficient for strains causing acute symptomatic than that for strains causing "asymptomatic" urinary tract infections, were investigated. Uroepithelial cells from fresh morning urine of healthy individuals and E. coli bacteria from patients with various forms of urinary tract infeciton...
متن کاملSensitivity of Human Leukemic Cells to Carvedilol
Background and Objective: Carvedilol, a non-specific β-blocker, has been used for treatment of hypertension, stroke and congestive heart failure. The therapeutic effects of β blockers in cancer patients have been shown. Carvedilol has considerable anti-inflammatory, anti-tumor and anti-angiogenic properties. In this study, the effects of carvedilol on proliferation of human U937 and Molt-4 leuk...
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...
متن کاملPhylogenetic analysis of Escherichia coli strains isolated from human samples
Escherichia coli (E. coli) is a normal inhabitant of the gastrointestinal tract of vertebrates, including humans. Phylogenetic analysis has shown that E. coli is composed of four main phylogenetic groups (A, B1, B2 and D). Group A and B1 are generally associated with commensals, whereas group B2 is associated with extra-intestinal pathotypes. Most enteropathogenic isolates, however, are assigne...
