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 کاملProbiotics, prebiotics and competitive exclusion for prophylaxis against bacterial disease.
The microbial population of the intestinal tract is a complex natural resource that can be utilized in an effort to reduce the impact of pathogenic bacteria that affect animal production and efficiency, as well as the safety of food products. Strategies have been devised to reduce the populations of food-borne pathogenic bacteria in animals at the on-farm stage. Many of these techniques rely on...
متن کاملImmunity, vaccination and the avian intestinal tract.
Defence of the intestinal mucosal surface from enteric pathogens is initially mediated by secretory IgA (SIgA). As oral immunization of non-replicating antigen induces minimal SIgA antibody titers, novel immunization strategies which selectively induce mucosal immune responses in mammals are now being assessed in chickens. The strategies reviewed include the route of antigen delivery, the incor...
متن کاملComparison of mucosal competitive exclusion and competitive exclusion treatment to reduce Salmonella and Campylobacter spp. colonization in broiler chickens.
Control of Salmonella spp. during the earliest phases of broiler production may provide the best opportunity to reduce human pathogens on processed broiler carcasses. Application of the "Nurmi concept" has been demonstrated to be an effective means in reducing Salmonella colonization among broiler chicks. In 1989, Aho et al. developed a competitive exclusion (CE) culture for control of Salmonel...
متن کاملEffectiveness of an Undefined Mucosal Competitive Exclusion Treatment to Control Salmonella in Turkeys during Brooding
Mucosal competitive exclusion (MCE) cultures generated from the mucosal scrapings of healthy adult turkeys were administered to commercial turkey poults. MCE-treated poults were placed on tom and hen farms with paired untreated control poults in adjacent houses. After 6 wk in the brood house, cecal droppings from control and treated flocks were collected and analyzed for the presence of salmone...
