[ 1 ] - Seroepidemiology of coxiellosis (Q fever) in sheep and goat populations in the northeast of Iran
Coxiella burnetii is the etiological agent of coxiellosis in animals and Q fever (a zoonotic disease) in humans. Cattle, sheep and goats are the main reservoirs of infection for humans. This serological survey was conducted to determine the seroprevalence of coxiellosis in sheep and goat populations in Khorasan Razavi province, Iran. Four hundred and sixty animals (255 sheep from 29 herds in 12...
[ 2 ] - Role of neutrophils in protection of udder from infection in high yielding dairy cows
Protection of the mammary gland against mastitis-causing pathogens is mediated by many factors in thegland and blood circulation. The professional phagocytic cells of bovine udder, polymorphonuclearneutrophils (PMN) and macrophages, comprise the first line of defense against invading mastitis pathogens.Most researchers now accept that the PMN is a key factor in the cows’ defense against intrama...
[ 3 ] - اثر افزایش تراکم نگه داری بر عملکرد رشد، غلظت هورمون کورتیزول و بیان ژن پروتئین شوک حرارتی در ماهی قزل آلای رنگین کمان (Oncorhynchus mykiss)
تراکم نگه داری به عنوان یک عامل استرس زای مزمن در آبزیپروری تلقی می شود. هدف از این مطالعه، مقایسه عملکرد رشد، تغییرات هورمون کورتیزول و بیان امآرانای ژن پروتئین شوک حرارتی (70 HSP) ماهی قزل آلای رنگین کمان (Onchorhynchus mykiss) در دو تراکم نگه داری متداول کشور در س...
[ 4 ] - Comparison of growth parameters, cortisol and muscle gene expression of rainbow trout reared in an open and water reuse system
Fish farming in recirculating aquaculture systems (RAS) has been expanding in the recent years, but the effects of water reuse are not well known. The aim of the present study was to compare the growth parameters, stress response and muscle stress- and growth- related gene expression of rainbow trout (Oncorhynchus mykiss) in open system (OS) versus water reuse system (WRS). For this purpose, yo...
