Comparative evaluation of molecular typing of strains from a national epidemic due to Salmonella brandenburg by rRNA gene and IS200 probes and pulsed-field gel electrophoresis.

In Switzerland in 1992 there was a prolonged series of outbreaks of human salmonellosis caused by a previously rare serotype, Salmonella brandenburg. In order to examine the genotypic basis of the epidemic, molecular typing was applied to representative strains of this serovar isolated between 1983 and 1992. These included sporadic human isolates up to 1985… (More)
