The aim of this study was to applicate and evaluate a SYBR Green real-time PCR for the specific detection of Salmonella spp. Specificity of the PCR method was confirmed with 48 Salmonella spp. and 5 non-Salmonella strains using invA gene primer. The average threshold cycle (CT) of Salmonella spp. was 11.83 ± 0.78 while non-Salmonella spp. was 30.86 ± 1.19. Correlation coefficients of standard curves constructed using CT versus copy number of Salmonella Enteritidis ATCC 13076 showed good linearity (R2 = 0.993; slope = 3.563). Minimum level of detection with the method was 102 colony forming units (CFU)/mL. These results suggested that the SYBR Green real-time PCR might be applicable for the specific detection of Salmonella spp. isolates.
