| Abstract |
|
Antigenic ompC genes of S. gallinarum, S. pullorum and S. dublin were characterized among Salmonella spp. isolated from chickens and other animals to identify genetic variation. Salmonella ompC gene fragment (1,027 bp) was amplified by PCR and the amplicons were cloned for comparison of nucleotide sequences. The identity of the sequences between S. gallinarum and S. pullorum, S. gallinarum and S. dublin, S. pullorum and S. dublin was 99.8%, 97.6% and 97.8%, respectively. Also, we found that ompC has some diversity between S. gallinarum and S. pullorum, and other Salmonella spp. which may be useful to type the organisms. Similar to diagnosis in other organisms, the TaqMan PCR method can be applied to rapid and accurate diagnosis of salmonellosis in chickens and other animals. We designed PCR primers and TaqMan probe for flagellin gene (fliC) for detection of Salmonella spp. by TaqMan PCR. The TaqMan PCR method was 10,000 times more sensitive than conventional PCR. |
