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 کاملInhibition of Campylobacter jejuni colonization in chicks by defined competitive exclusion bacteria.
Campylobacter enteritis in humans has been linked to consumption of chicken. Reducing Campylobacter jejuni colonization in chickens can potentially reduce Campylobacter infections in humans. In this study, the reduction of C. jejuni colonization in chicks by oral administration of defined competitive exclusion (CE) cultures, 2.5% dietary carbohydrates, or CE cultures and carbohydrates was exami...
متن کاملColonization of cattle intestines by Campylobacter jejuni and Campylobacter lanienae.
The location and abundance of Campylobacter jejuni and Campylobacter lanienae in the intestines of beef cattle were investigated using real-time quantitative PCR in two studies. In an initial study, digesta and tissue samples were obtained along the digestive tract of two beef steers known to shed C. jejuni and C. lanienae (steers A and B). At the time of slaughter, steer B weighed 540 kg, comp...
متن کاملPassive immunization to reduce Campylobacter jejuni colonization and transmission in broiler chickens
Campylobacter jejuni is the most common cause of bacterium-mediated diarrheal disease in humans worldwide. Poultry products are considered the most important source of C. jejuni infections in humans but to date no effective strategy exists to eradicate this zoonotic pathogen from poultry production. Here, the potential use of passive immunization to reduce Campylobacter colonization in broiler ...
متن کاملColonization of gastrointestinal tracts of chicks by Campylobacter jejuni.
Bacterial enumeration and histologic examination of organs and tissues of 8-day-old chicks 7 days after peroral inoculation with Campylobacter jejuni revealed that the organism colonized primarily the lower gastrointestinal tract. The principal sites of localization were the ceca, large intestine, and cloaca, where densely packed cells of C. jejuni were observed in mucus within crypts. Examinat...
