Pulsed-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 کاملComparison of Genetic Patterns of E. coli Strains Isolated from Patients with Cystitis and Pyelonephritis, Using Pulsed Field Gel Electrophoresis
Background & Aims: Urinary tract infection (UTI) is one of the most frequently acquired bacterial infections caused by a large genetically heterogeneous group of Escherichia coli which are called uropathogenic E. coli (UPEC). Cystitis and pyelonephritis are two most common symptoms seen in patients with UTI. The genetic diversity of this organism has hampered the identification of UTI strains a...
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 for Salmonella Infection
To detect Salmonella clusters, public health laboratories perform pulsed-field gel electrophoresis (PFGE) that provides a PFGE pattern, or DNA fingerprint. If the PFGE patterns of isolates from >2 persons are indistinguishable, the responsible bacteria may be related to a common source (1–3). PulseNet is a network of public health laboratories coordinated by the Centers for Disease Control and ...
