Immunochemical analyses of 85 isolates of 17 Salmonella serovars using polyclonal antiserum to SEF21, the type 1 fimbriae of Salmonella enteritidis, demonstrated antigenic relatedness among both type 1 and type 2 fimbriae of Salmonella. However, anti-SEF21 antiserum was not entirely suitable as a Salmonella diagnostic probe due either to a variability of, or a rare deficiency of, detectable fimbriae. Partial amino acid sequence analyses of the SEF21 structural fimbrin protein revealed 99% homology to Salmonella typhimurium FimA. Therefore, oligonucleotide probes for Salmonella detection were designed following sequencing of S. enteritidis fimA and comparison to the corresponding genes of S. typhimurium, Escherichia coli, Klebsiella pneumoniae and Serratia marcescens. One oligonucleotide probe hybridized to all 612 Salmonella isolates of 89 serovars tested while two other probes detected 97.5% and 99.7% of the isolates. Three consistently weak positive reactions were obtained, therefore, inclusivity was optimized by identification of a Salmonella-specific tctC DNA probe that detected 609 of 612 Salmonella isolates. No hybridization of these Salmonella probes was detected to 250 other Enterobacteriaceae isolates or to 14 other eubacterial species. Therefore, in combination, DNA probes to fimA and tctC proved to be highly reliable diagnostics for Salmonella bacteria. Accordingly, PCR assays targeting fimA and tctC were developed.
