Evaluation of the specificity o Salmonella P using various intestinal bacterial species * f CR primers virulence gene , Salmonella enterotoxin gene ( stn ) , invA gene , Fur-regulated gene , histidine transport operon , junction between SipB and SipC virulence genes , Salmonella-specific repetitive DNA fragment , and multiplex targeting invA gene and spvC gene of the virulence plasmid .
Gene targets included : 16S rDNA ( Lin and Tsen 1996 ) , a Salmonella pathogenicity island I virulence gene ( hilA ) ( Guo et al. 2000 ) , Salmonella enterotoxin gene ( stn ) ( Makino et al. 1999 ) , invA gene ( Ferretti et al. 2001 ) , Fur-regulated gene ( iroB ) ( Bäumler et al. 1997 ) , histidine transport operon ( Cohen et al. 1993 ) , the junction between sipB and sipC virulence genes ( sipB-sipC ) ( Carlson et al. 1999 ) , a Salmon-ella-specific repetitive DNA fragment ( Jitrapakdee et al. 1995 ) , and a multiplex targeting invA gene and spvC gene of the virulence plasmid ( invA/spvC ) ( Chiu and Ou 1996 ) .
