The conventional cultural, biochemical and serological methods for detection and identification of Salmonella in fecal swabs were applied and the results were compared with those obtained by molecular screening assays using conventional PCR and Real-Time PCR techniques. The obtained results revealed that 9.1% of were positive for Salmonella species using conventional culture methods while 11.8% were positive by conventional PCR and 15.5% by using Real-Time PCR were found to be positive for Salmonella species. The results of the three methods were compared to each other. From the present work it could be concluded that the Real-Time PCR assay has highest sensitivity and specificity for detection of Salmonella species in dairy farms ER -
