Genetic and physicochemical characterization of Escherichia coli strains carrying fused F' elements derived from KLF1 and F57.
Although the two F' elements, F57 (carrying his(+)) and KLF1 (carrying leu(+)), cannot normally coexist in the same cell, crosses between RecA(-) strains of Escherichia coli carrying these two elements gave rise, at a low frequency, to progeny carrying both the his(+) and leu(+) markers in an extrachromosomal state. Genetic studies showed that the his(+) and leu(+) markers were now linked, and ...
متن کاملImmunological and physicochemical characterization of heat-labile enterotoxins isolated from two strains of Escherichia coli.
Heat-labile enterotoxins from Escherichia coli strains of human and porcine origins had identical subunit composition, arrangement, and size in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Immunological differences recently described by others were shown to reside exclusively in the B subunits.
متن کاملShigella and enteroinvasive Escherichia coli strains are derived from distinct ancestral strains of E. coli.
The differentiation between Shigella subspecies, and the phylogenetic position of Shigella clones within Escherichia coli clones was determined by analysis of restriction fragment length polymorphisms of rDNA (ribotyping). Seventy-five Shigella strains belonging to the four subspecies and 13 enteroinvasive E. coli (EIEC) strains were compared with the 72 E. coli strains of the ECOR collection, ...
متن کاملPhysicochemical characterization of ribonucleoside diphosphate reductase from Escherichia coli.
Ribonucleotide reductase from Escherichia coli consists of two nonidentical subunits, proteins Bl and B2. Affinity chromatography resulted in a Bl preparation which appeared homogeneous during polyacrylamide gel electrophoresis and ultracentrifugation. The molecular weight was 160,000 by sedimentation equilibrium centrifugation using a partial specific volume of 0.706 ml per g at 4”. Protein Bl...
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...
