Comparison 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 کاملComparison of Experimental Competitive-exclusion Cultures for Controlling Salmonella Colonization in Broiler Chicks
The efficacy of three different types of experimental competitive exclusion (CE-A, CE-B and CE-C) cultures against Salmonella Kedougou (SK) NCTC 12173, resistant to nalidixic-acid resistant (Nal), in one-day-old broiler chicks, in four treatments with three replicates in each treatment, was evaluated. The mean logarithmic counts of Salmonella program of feces were 0.4 L in the group treated wit...
متن کاملCompetitive exclusion of heterologous Campylobacter spp. in chicks.
Chicken and human isolates of Campylobacter jejuni were used to provide oral challenge of day-old broiler chicks. The isolation ratio of the competing challenge strains was monitored and varied, depending upon the isolates used. A PCR-restriction fragment length polymorphism assay of the flagellin gene (flaA) was used to discriminate between the chick-colonizing isolates. Our observations indic...
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...
متن کاملEmergence of Salmonella enteritidis outbreaks in broiler chickens in the Lebanon: epidemiological markers and competitive exclusion control.
This study investigates the first emergence of Salmonella Enteritidis outbreaks among chickens in the Lebanon and identifies the epidemiological markers of selected recovered Enteritidis strains. In addition, the authors evaluate a competitive exclusion approach to control infection in broiler chickens by Enteritidis organisms which possess the prevalent identified markers. The basic procedure ...
