DNA fingerprinting of Escherichia coli O157:H7 strains by pulsed-field gel electrophoresis.
Pulsed-field gel electrophoresis of genomic DNA was carried out on Escherichia coli O157:H7 strains from different geographic locations to determine its value in an epidemiological survey of O157 infections. Pulsed-field gel electrophoresis of XbaI-digested DNA fragments clearly separated E. coli O157:H7 strains from nontoxigenic E. coli O157:H19, O157:H43, and O157:H45 strains and from Shiga-l...
متن کاملFingerprinting Viral Assemblages by Pulsed Field Gel Electrophoresis (PFGE)
Viruses are the most abundant microorganisms in marine and freshwater environments and perhaps the most genetically diverse (Fuhrman and Suttle, 1993). Counting viruses in aquatic samples is now a routine matter, but assessing the diversity and dynamics within complex assemblages is still a challenge. DNA-based fingerprinting approaches, which rely on amplification of rRNA gene fragments by PCR...
متن کاملMacrorestriction fingerprinting of "Streptococcus milleri" group bacteria by pulsed-field gel electrophoresis.
Although isolates of the "Streptococcus milleri" group (SMG) of bacteria are regarded as members of the commensal microflora of the body, they are frequently encountered in purulent infections from a range of body sites. The genetic diversity of 91 epidemiologically unrelated SMG isolates (including 37 commensal strains and 49 disease-associated strains) was analyzed by macrorestriction fingerp...
متن کاملMolecular Typing of Acinetobacter Baumannii Clinical Strains in Tehran by Pulsed-Field Gel Electrophoresis
Background & Objective : Currently, Acinetobacter baumannii is an important nosocomial pathogen insofar as its hospital outbreaks have been described from various geographical areas. Since the discrimination of strains within a species is important for delineating nosocomial outbreaks, this study was conducted with the aim of genotyping the A. baumannii clinical strains in Tehran via the pulsed...
متن کاملCharacterization of Streptococcus pneumoniae ophthalmic, systemic & commensal isolates by pulsed-field gel electrophoresis & ribotyping.
BACKGROUND & OBJECTIVE Streptococcus pneumoniae is common in ocular and systemic infections and is a part of normal nasopharyngeal flora. Very few studies regarding genetic analysis of S. pneumoniae isolates causing eye infections are available. This study was undertaken to do pulse field gel electrophoresis (PFGE) analysis and ribotyping of S. pneumoniae isolates obtained from eye infections, ...
