Identification and Discrimination of Salmonella Enteritidis, S. Pullorum, S. Gallinarum and S. Dublin Using Salmonella Specific Genomic Regions Amplification Assay
Background: DNA amplification method has been developed for identifying and discriminating Salmonella serovars, using specific primers at the genus and serovar levels and to identify the S. Enteritidis, S. Dublin, S. Gallinarum and S. Pullorum. Objectives: This study was conducted for molecular identification and discrimination among some important Salmonella serovars. Methods: Fifty isolates o...
متن کاملThermolabile Sulfite Reductase from Salmonella pullorum'
The biochemical basis for sulfite accumulation by sulfate-using revertants of Salmonella pullorum was determined. All of the sulfate-using mutants isolated from wild-type S. pullorum accumulated sulfite when grown at 37 but not at 25 C. The specific activity of reduced nicotinamide adenine dinucleotide (NADPH)-dependent sulfite reductase (H2S-NADP oxidoreductase, EC 1.8.1.2) and of reduced meth...
متن کاملStudy on phenotypic characteristics of Salmonella gallinarum and Sallmonella pullorum isolates based on biochemical and antimicrobial susceptibility tests in Iran
Salmonellosis is a very important disease of avian species because of its huge economic impact, worldwide distribution and difficulty posed in its control. Fowl typhoid and pullorum disease, is caused by Salmonella enterica subsp enterica serovar Gallinarum biovar Gallinarum and Pullorum. The purpose of this study was to investigate the biochemical characteristics and antimicrobial susceptibili...
متن کاملIsolation and characterization of bacteriophages of Salmonella enterica serovar Pullorum.
In this study, 2 bacteriophages of Salmonella Pullorum were isolated using an enrichment protocol and the double agar layer method. They were named PSPu-95 and PSPu-4-116, respectively, against clinical isolates of Salmonella Pullorum SPu-95 and SPu-116. The host ranges of the 2 bacteriophages were determined by performing spot tests with 20 bacteria strains. Both bacteriophages had wide host r...
متن کاملImmunogenicity of living and heat-killed Salmonella pullorum vaccines.
Specific pathogen-free CD-1 and C57Bl mice were infected in a hind footpad with 5 x 10(4) viable Salmonella enteritidis cells or 10(7) viable S. pullorum cells. The resulting bacterial growth within the footpad, the draining lymph nodes, and the liver and spleen was followed for 14 days. Mice vaccinated with live S. enteritidis rapidly developed an effective antibacterial resistance to both int...
