Association study in naturally infected helminth layers shows evidence for influence of interferon-gamma gene variants on Ascaridia galli worm burden
Single nucleotide polymorphisms (SNPs) in the genes for interleukin-4, -13 and interferon-gamma, and 21 additional SNPs which previously had been significantly associated with immune traits in the chicken, were genotyped in white and brown layer hens and analyzed for their association with helminth burden following natural infections. A nucleotide substitution located upstream of the promoter o...
متن کاملImmune gene expression in the spleen of chickens experimentally infected with Ascaridia galli.
Ascaridia galli is a gastrointestinal nematode infecting chickens. Chickens kept in alternative rearing systems or at free-range experience increased risk for infection with resulting high prevalences. A. galli infection causes reduced weight gain, decreased egg production and in severe cases increased mortality. More importantly, the parasitised chickens are more susceptible to secondary infec...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولThe effect of excess dietary manganese on uninfected and Ascaridia galli infected chicks.
The effect of dietary manganese from two different sources on chicks (uninfected and infected with Ascaridia galli) was studied. Chick diet was supplemented with 0.9 g Mn2+ kg-1 food either in the form of MnSO4.H2O or 2Gly. MnCl2.2H2O for 20 days. Chicks were divided into six groups: group 0, control; group 1, control + MnSO4.H2O; group 2, control + 2Gly.MnCl2.2H2O; group 3, infected with A. ga...

A survey was conducted to determine the prevalence of gastrointestinal helminthes in local chickens, broilers and layers slaughtered in Makurdi metropolis between September 2007 and April 2008. A total of 440 samples were collected from male and female chickens. Of the total samples examined, 200(45.5%) were from domestic chicken, 140(31.8%) from broilers and 100(22.7%) from layers. Of the tota...
