Competitive exclusion of Salmonella enteritidis by Salmonella gallinarum in poultry.
Salmonella Enteritidis emerged as a major egg-associated pathogen in the late 20th century. Epidemiologic data from England, Wales, and the United States indicate that S. Enteritidis filled the ecologic niche vacated by eradication of S. Gallinarum from poultry, leading to an epidemic increase in human infections. We tested this hypothesis by retrospective analysis of epidemiologic surveys in G...
متن کاملDifferential cytokine expression in avian cells in response to invasion by Salmonella typhimurium, Salmonella enteritidis and Salmonella gallinarum.
Salmonella enterica is a facultative intracellular pathogen that is capable of causing disease in a range of hosts. Although human salmonellosis is frequently associated with consumption of contaminated poultry and eggs, and the serotypes Salmonella gallinarum and Salmonella pullorum are important world-wide pathogens of poultry, little is understood of the mechanisms of pathogenesis of Salmone...
متن کاملIdentification 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 کاملMicrobial-Resistant Salmonella enteritidis Isolated from Poultry Samples
Background: Multidrug resistance in Salmonella enteritidis isolates is a public health problem worldwide; the present study, therefore, was designed for antimicrobial-resistance determination in this strain. Methods: Salmonella strains isolated from poultry samples by biochemical positive and negative tests were subjected to PCR and identified as Salmonella enteritidis. For detection and ide...
متن کاملEnterotoxigenicity of Salmonella Gallinarum strains isolated from poultry
Twenty Salmonella Gallinarum strains isolated from poultry were tested for Enterotoxigenicity activity using rabbit and chicken ligated intestine loop technique and the rabbit vascular permeability factor activity test. One ml of cell-free filtrate (CFF) of each isolate was injected into chicken ligated loops and rabbit ligated loops, one ml of whole cell culture(WCC) of each isolate was inject...
