The LOD values for qPCR and conventional culture methods (ISO and MSRV) were in the same order, allowing the detection of Salmonella at approximately 10 CFU/25 g. Isolation and Biochemical Identification of Salmonella spp. Salmonella spp. J. Vet. Between 27 September 2014 and 15 February 2015, a total of 200 samples were collected from cloacal swabs and cecal contents from different sources and ages at Al-Diwaniyah Province. Based on the results reported in the present study, the recommended culture method for the recovery/isolation of Salmonella from swine fecal samples consists of inoculating 10 g of feces into 100 ml of tetrathionate broth and incubating at 37°C for 48 hr, subculturing 10 ml of the tetrathionate broth into 100 ml RV broth and incubating at 37 . Every sample was collected from 7 different spots in the chicken skin facility (Yougin, Gyeonggi-do, Korea). samples analyzed (82.6%) were correctly identified as Salmonella positive by multiple culture methods, only when combining results of methods 2 and 3 or 2 and 5 were all 46 knownSalmonella-positive samples correctly identified. All the samples were wrapped separately in sterile polyethylene bags and plastic bags and transported to the laboratory for microbial analysis. The routine detection of Salmonella in foods is a important part of public health programs because the presence of Salmonella in food can cause health problems. Different combinations of Salmonella isolation procedures, including sample size, preenrichment broth, enrichment broth, enrichment temperature, and isolation medium, were used. A total of 50 Salmonella enterica serovar Javiana isolates, isolated from food, environmental and clinical samples, were analyzed for antibiotic resistance, presence of virulence genes, plasmids and plasmid replicon types.
