The Prevalence of Campylobacter amongst a Free-Range Broiler Breeder Flock Was Primarily Affected by Flock Age
Campylobacter successfully colonizes broiler chickens, but little is known about the longer term natural history of colonization, since most flocks are slaughtered at an immature age. In this study, the prevalence and genetic diversity of Campylobacter colonizing a single free-range broiler breeder flock was investigated over the course of a year. The age of the flock was the most important fac...
متن کاملCryptic species within the Tetratrichomonas gallinarum species complex revealed by molecular polymorphism.
Tetratrichomonas gallinarum is a widespread intestinal parasite of galliform and anseriform birds. The pathogenicity of this species is controversial, presenting an unsettled problem as yet. We analysed the polymorphism and genetic relationship among 29 isolates of T. gallinarum obtained from eight bird species and five T. gallinarum-like isolates from the oral cavity and lower respiratory trac...
متن کاملThe long-term dynamics of Campylobacter colonizing a free-range broiler breeder flock: an observational study
A free-range broiler breeder flock was studied in order to determine the natural patterns of Campylobacter colonization over a period of 63 weeks. Campylobacter sequence types (STs) were not mutually exclusive and on average colonized only 17.7% of the birds tested at any time. Campylobacter STs typically reached a peak in prevalence upon initial detection in the flock before tailing off, altho...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولPregnancy Disease - A Flock Perspective
Pregnancy disease (pregnancy toxemia, twin lamb disease, lambing sickness, lambing paralysis or lambing ketosis) typically affects ewes during the last 2 to 4 weeks of pregnancy and is a common cause of ewe and lamb loss in Michigan flocks. Overconditioned or thin ewes, usually pregnant with multiple fetuses, are most commonly affected and clinical cases are generally limited to older ewes duri...
