Detection of Virulence Gene (inva) in Salmonella Isolated from Meat and Poultry Products

Detection of pathogenic Salmonella isolated from meat and poultry products by detecting virulence invA gene using PCR technique.A total of100 meat and poultry products samples were collected from shops and supermarkets; including 50 meat products samples and 50 poultry products. Salmonella was detected by conventional isolation methods and then PCR was carried out to detectinvA gene in isolated Salmonella.It was observed that 16% of samples were positive for Salmonellaisolation; 26% (13/50) in meat samples and 6% (3/50) in poultry samples. All Salmonella isolates were positive for the invA gene.Meat and poultry products were contaminated with pathogenic Salmonella and all isolated Salmonella contained the virulence gene, invA gene, assuring that these isolates are pathogenic and virulent strains. Hygienic measures should be undertaken to reduce contamination of meat and poultry products with pathogenic Salmonella.
