AbstractIn this study we used and evaluated three rapid molecular typing methods for the identification of three frequent, clinically significant Salmonella serovars on the basis of the ease, simplicity and reproducibility of the chosen methods. We determined the genetic diversity among several isolates of Salmonella enter tidis, S. typhimwium and S. virchow, and compared them with other enterobacteria by using the repetitive extragenic palindromic (REP) sequences, the enterobacterial repetitive intergenic consensus (ERIC) sequences, and the 16S-23S rDNA intergenic spacer region (ITS 1). The objective was to evaluate their potential application to discriminate among members of the species Salmonella enterica subspecies enterica using the genetic diversity of the group found by genomic fingerprinting. The three different serovars of Salmonella studied gave reproducible and distinguishable profiles using whichever of the above mentioned polymerase chain reaction (PCR) methods assayed. The conserved patterns in each serovar allowed for easy differentiation from other serovars of Salmonella. © Springer-Verlag 2000.
