| molecular typing of enterohemorrhagic escherichia coli o157:h7 isolated in okayama prefecture using pulsed field gel electrophoresis and random amplification of polymorphic dna. | three outbreaks and many isolated cases of enterohemorrhagic escherichia coli o157:h7 occurred in 1996 and 1997 in okayama prefecture, japan. in an attempt to investigate the route of these infections, the strains isolated from the 3 outbreaks (total 33 strains) and 15 isolated cases (total 15 strains) were investigated using random amplification of polymorphic dna (rapd) and pulsed-field gel electrophoresis (pfge). in addition, 10 strains from an outbreak in tojo cho, hiroshima prefecture (june ... | 1999 | 10488407 |
| genomic analysis of a multidrug-resistant strain of enterohaemorrhagic escherichia coli o157:h7 causing a family outbreak in japan. | a family outbreak of enterohaemorrhagic escherichia coli (ehec) o157:h7 infection occurred in october 2003 in the hiroshima prefecture, japan. four isolates of ehec o157:h7, 03064, 03065, 03066 and 03067, were recovered from a 1-year-old daughter, mother, father and 3-year-old daughter, respectively. all ehec o157:h7 isolates were positive for stx1 and stx2 shiga toxins. surprisingly, dna fingerprinting profiles obtained by pfge showed that the first isolate, 03064, had unique xbai and blni prof ... | 2005 | 16091439 |
