Identification of clinical isolates of Leptospira spp by pulsed field gel-electrophoresis and microscopic agglutination test.
Twenty-five clinical isolates of Leptospira spp were characterized by microscopic agglutination test (MAT) and pulsed field gel-electrophoresis (PFGE) in comparison with 23 reference Leptospira serovars and with the saprophytic L. biflexa serovar Patoc. PFGE DNA profiling was more specific and reliable than MAT.
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 کاملRapid identification of Pseudomonas aeruginosa by pulsed-field gel electrophoresis
Twenty clinical Pseudomonas aeruginosa isolates recovered from patients admitted to The General Hospital in Ismailia Governorate (Egypt) were examined in this study. We analysed P. aeruginosa ATCC 9027 (as a control strain) and 19 of the isolates after digestion with SpeI restriction endonuclease. After this we conducted a pulsed-field gel electrophoresis (PFGE) and typed the obtained 10 unique...
متن کاملStandardization and interlaboratory reproducibility assessment of pulsed-field gel electrophoresis-generated fingerprints of Acinetobacter baumannii.
A standard procedure for pulsed-field gel electrophoresis (PFGE) of macrorestriction fragments of Acinetobacter baumannii was set up and validated for its interlaboratory reproducibility and its potential for use in the construction of an Internet-based database for international monitoring of epidemic strains. The PFGE fingerprints of strains were generated at three different laboratories with...
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...
