WebMETHODS: Two hundred eleven confirmed ESBL-producing isolates of K. pneumoniae were collected from January 1998 to June 2000. The isolates were characterized by various typing methods, including antibiogram (9 antimicrobial agents), computer-based ribotyping, pulsed-field gel electrophoresis (PFGE), and isoelectric focusing of beta-lactamase. WebGenetic relatedness among bla NDM-5-positive isolates was determined by pulsed-field gel electrophoresis (PFGE). In brief, bacterial cells harvested from stationary-phase culture …

Pulsed Field Gel Electrophoresis – The Basics

WebDec 11, 2024 · Pulse field gel electrophoresis (PFGE) Conventional agarose gel electrophoresis cannot separate linear double stranded DNA molecules that have radius of gyration, which is larger than the pore size of the gel. However, with certain changes in the orientation of electric field with respect to the gel, large DNA fragments can be resolved. There are various types of PFGE methods, such as FIGE, TAFE, CHEF, OFAG, PHOGE and PACE, that are used for isolating and typing DNA with large pieces. The choice of which method to use depends on the financial resources available and the specific goals of the study. This is a technique that separates large segments of DNA by periodically flipping two fields at a straight angle. The movement of DNA molecules is facilitated by shorter time pulses or less forc… the galliard vadi istanbul menü
