Detection of InvA Gene in Isolated Salmonella from Broilers by PCR Method
The presence of Salmonella was detected in 192 samples of poultry carcasses from poultry farms in Shiraz province (Iran). A total of 30 Salmonella isolates were found in chicken samples (15.6%), by conventional culturing and confirmed by PCR and serology methods. Strains of serogroup D1 were the most prevalent strains, followed by serogroups C1, B and C2. All strains were subjected to Salmonell...
متن کاملDetection of Salmonella spp. from some wild captive herbivores in Iran and determination of serogroup, antibiotic susceptibility and presence of invA gene in the isolated strains
Salmonella spp. are zoonotic enteric bacteria able to infect humans, livestock and wildlife. The aim of this study was to investigate the prevalence of Salmonella (spp.) and to determine antibiotic susceptibility, serogrouping and presence of invA gene (Salmonella Invasion Gene A) in the detected strains in wild captive herbivores in Iran. The fecal samples of 103 animals from 8 different speci...
متن کاملDetection of Colicin genes by PCR in Escherichia coli isolated from cattle in Shiraz-Iran
A variety of probiotic bacteria have been tested to control animal and foodborne pathogenic bacteria in livestock. The mechanism of inhibition of pathogenic bacteria for several of those probiotic microorganisms is mediated by the production of bacteriocins. Colicins are probably the group of bacteriocins that have been most thoroughly characterized. Colicins are antimicrobial proteins produced...
متن کاملPCR detection of Escherichia coli O157:H7 directed from slaughtered cattle in Shiraz, Iran
Escheric hia coli O157:H7 lives in the intestines of healthy cattle, and can contaminate meat during slaughtering pr actices . Detection of the low infectious dosage of bacterium requires a sensitive method. We developed polymerase chain reaction (PCR) assays to detect the gene Stx2 irrespective of the bacterial serotype. In this study, the detection limit of the PCR protocol in detecting Stx...
متن کاملDetection of Salmonella spp contamination of carcasses slaughtered in poultry abattoir in Mashhad, Iran
A total of 60 neck skin swab samples were taken from 12 different broiler flocks after the chilling stage of processing at a commercial broiler slughtering facility in Mashhad. The presence of Salmonella was assessed by conventional culture method and confirmed by using poly O and poly H antiserum in serotyping. PCR amplification of invA gene as a specific method for detection of Salmonella w...
