Molecular genotyping of multinational ovine and caprine Corynebacterium pseudotuberculosis isolates using pulsed-field gel electrophoresis.
Caseous lymphadenitis (CLA) is a chronic, suppurative disease, with a worldwide distribution, caused by Corynebacterium pseudotuberculosis. The clinical manifestation of CLA is known to vary between different countries, and has been postulated to be due to differences in the strains present in these countries. Forty-two sheep and goat isolates of C. pseudotuberculosis from Australia, Canada, Ei...
متن کاملPulsed-field gel electrophoresis.
DNA molecules in an agarose matrix elongate and migrate toward the anode when exposed to an electric field. An agarose matrix represents a highly irregular network with pores of various dimensions, large open areas, and regions with different densities. During electrophoresis, migration will be retarded by obstructions that prevent sieving by size and result in "end-on" migration as if through ...
متن کاملAeromonas Isolates from Human Diarrheic Stool and Groundwater Compared by Pulsed-Field Gel Electrophoresis
Gastrointestinal infections of Aeromonas species are generally considered waterborne; for this reason, Aeromonas hydrophila has been placed on the United States Environmental Protection Agency Contaminant Candidate List of emerging pathogens in drinking water. In this study, we compared pulsed-field gel electrophoresis patterns of Aeromonas isolates from stool specimens of patients with diarrhe...
متن کاملPulsed homogeneous orthogonal field gel electrophoresis (PHOGE).
A versatile system (PHOGE) has been developed that allows resolution of molecules of DNA megabase pair size by the use of homogeneous, orthogonal, pulsed fields. The resulting electrophoretograms have characteristics that differ from those produced by other systems for pulsed field electrophoresis. Molecules in a two-fold range of sizes can be separated with maximum resolution, or a much larger...
متن کاملPulsed-field gel electrophoresis of circular DNA.
Mobility of supercoiled (form I) and nicked circular (form II) plasmid DNAs was determined on two major forms of pulsed-field electrophoresis, CHEF and OFAGE. Plasmids with molecular lengths ranging from 2.30 to 17.8 kilobase pairs (kb) were used with Saccharomyces cerevisiae chromosomes as standards. Agarose gel concentrations were varied from 0.3 to 2.0 percent, with higher percentage gels re...
