knowledge of virus and replication kinetic is one of the most important issues in the vaccine production. the present study aimed to evaluate the best harvesting time of h9n2 avian influenza virus (aiv) vaccine strain inoculated in specific pathogen free (spf) embryonated chicken eggs (ece)s. for this purpose, 10-5 dilution of aiv (a/chicken/iran/99/h9n2) was inoculated into 336, 11-day old ece...

Egg white is an important contributor to the protection of eggs against bacterial contaminations during the first half of incubation (day zero to 12), prior to the egg white transfer into the amniotic fluid to be orally absorbed by the embryo. This protective system relies on an arsenal of antimicrobial proteins and on intrinsic physicochemical properties that are generally unfavorable for bact...

AIM The objective of the present study was to examine pock forming ability of field strain and vaccine strain of fowl pox virus (FPV) in chorioallantoic membrane (CAM) of embryonated chicken eggs and its adaptation in chicken embryo fibroblast (CEF) cell culture. MATERIALS AND METHODS Dry scabs were collected from 25 affected birds in glycerin-saline and preserved at 4°C until processed. Viru...

Chicken egg yolk is a rich source of nutrients providing high quality proteins, vitamins, minerals, carotenoids and antioxidants. Chicken egg yolk, recovered from whole egg within 24 hours post-lay has been utilized as a starting material in the preparation of a dietary supplement that has been demonstrated to lead to gains in muscle mass in a human clinical study. Further, an oil derived from ...

The growth kinetics of avian infectious bronchitis (AIB) virus in vitro have been investigated previously using different systems, including embryonated chicken eggs (Hitchner and White, 1955), and cell cultures of chick embryo kidney (Lukert, 1965 ; Bulow, 1966; Akers and Cunningham, 1968) or chick embryo liver (Lukert, 1965). Organ cultures of ciliated epithelium have been employed in various...

wide fluctuations of the prices of chicken and egg along with the containment of these fluctuations always matter to producers, consumers and government. these fluctuations are affected by various factors on the supply and demand sides of the product and its inputs. the results of this research are as follows: contributing 1.5 and 1 per cent to the world production of chicken (76.3 million tons...

A new system, the Toxorhynchites-fluorescent antibody (TFA) test in which the larvae of Toxorhynchites splendens mosquitoes were used for the detection of bluetongue virus (BTV) from Culicoides midges, was developed. Twenty-seven pools of Culicoides midges were collected from bluetongue-prone areas of Tamil Nadu by use of the light-trap and suction-trap methods. A suspension of each pool was in...
