Poultry is a major reservoir for foodborne Salmonella serovars. Salmonella Typhimurium, Salmonella Enteritidis, Salmonella Heidelberg, Salmonella Kentucky, and Salmonella Senftenberg are the most prevalent serovars in U.S. poultry. Information concerning the interactions between different Salmonella species and host cells in poultry is lacking. In the present study, the above mentioned Salmonel...

salmonella enterica serovar typhimurium and s.enterica serovar enteritidis are the most frequently isolated serovars from food-borne diseases throughout the world. according to their antigenic profiles, salmonella shows different disease syndromes and host specificities. it is necessary and important to discriminate salmonella serovars from each other in order to ensure that each pathogen and i...

salmonella is one of the most important zoonotic pathogens with many virulence factors playing a major role in its pathogenesis. the aims of this study were to detect spva, int2 and invc virulence genes of different salmonella serotypes isolated from various clinical animal and human sources, and to investigate antibiotic resistance patterns among these serotypes. using a pcr assay, a total of ...

background :  young chickens are more susceptible to salmonella colonization than older ones that have developed resistance with age as native microflora become established.   methods :  in this study, two groups of fertile eggs were inoculated with 20 cfu of hila or parent strains of s . enteritidis . presence and number of salmonella cells inside the homogenized egg contents were determined on...

Cockroaches were collected from hospitals, houses and poultry sheds in various parts of Isfahan (Iran) and identified to species. In total, seven species of cockroaches in seven genera were identified: Blatta lateralis, Polyphaga aegyptiaca, Arenivaga roseni and Parcoblatta spp. Three species Periplaneta americana, Blattella germanica and Supella longipalpa (Blattidae and Blattellidae) were mor...

the purpose of this study was to survey infections with salmonella spp. in poultry flocks in the vicinity of tehran and to determine the most frequent serogroups and serotypes implicated. twenty-eight samples of pullet, layer, and broiler flocks were randomly collected (n=1463), including freshly dropped feces from live birds or visceral organs from dead birds. in most flocks, 60 samples were t...

Background: Salmonella is one of the most common food-borne pathogens that can cause illness. In this study, the sensitivity and the specificity of Aptamer-Magnetic bead Separation-Polymerase Chain Reaction (AMS-PCR) method were determined for Salmonella spp. detection. Methods: Different concentrations of Salmonella enterica were mixed with streptavidin-magnetic beads coated with biotinylated...

AIM This work was conducted to study the phenotypic and genotypic characterization of locally isolated Salmonella strains (Salmonella Pullorum, Salmonella Enteritidis, and Salmonella Typhimurium) from poultry used in the preparation of Salmonella antigens in Egypt. MATERIALS AND METHODS The phenotypic characterization of Salmonella strains was done using standard microbiological, biochemical,...
