| multiple-locus variable-number tandem-repeats analysis of listeria monocytogenes using multicolour capillary electrophoresis and comparison with pulsed-field gel electrophoresis typing. | the multiple-locus variable-number tandem-repeats analysis (mlva) method for genotyping has proven to be a fast and reliable typing tool in several bacterial species. mlva is in our laboratory the routine typing method for salmonella enterica subsp. enterica serovar typhimurium and escherichia coli o157. the gram-positive bacteria listeria monocytogenes, while not isolated as frequent as s. typhimurium and e. coli, causes severe illness with an overall mortality rate of 30%. thus, it is importan ... | 2008 | 18096258 |
| epidemiology of salmonella typhimurium o:4-12 infection in norway: evidence of transmission from an avian wildlife reservoir. | in 1987, a nationwide outbreak of salmonella typhimurium o:4-12 infection traced to contaminated chocolate bars occurred in norway. in the 5 years after the outbreak, elevated numbers of sporadic cases caused by the epidemic strain of salmonella were detected, followed by a decline in subsequent years. to characterize the epidemiology of this infection, the authors analyzed information concerning all sporadic cases reported in norway from 1966 to 1996. of the 153 patients infected by the outbrea ... | 1998 | 9554419 |
| comparison of epidemiological marker methods for identification of salmonella typhimurium isolates from an outbreak caused by contaminated chocolate. | plasmid profile analysis, restriction endonuclease analysis, and multilocus enzyme electrophoresis were used in conjunction with serotyping, bacteriophage typing, and biochemical fingerprinting to trace epidemiologically related isolates of salmonella typhimurium from an outbreak caused by contaminated chocolate products in norway and finland. to evaluate the efficiency of the epidemiological marker methods, isolates from the outbreak were compared with five groups of control isolates not known ... | 1989 | 2674198 |
