Seroprev Alence and Pathology of Egg Drop Syndrome (eds-76) in Commercial Chicken Layers
نویسنده
چکیده
From September 1994 to April 1996, the aetiology of sudden decrease in egg production in commercial layer flocks was investigated. Clinical manifestations were recorded and the egg-shell quality was evaluated in 80 affected flocks. Serological screening was conducted twice at fortnightly intervals to record antibody titres against egg drop syndrome (EDS). Out of 80 flocks with lowered production, 34 (42.5 %) flocks were serologically positive for EDS. No specific gross lesions were observed but histopathological alterations were seen in the oviducts. Based on these findings, the farmers were advised to vaccinate their flocks against EDS between the age of 14-16 weeks using killed vaccines.

Egg drop syndrome (EDS) is caused by a hemagglutinating adenovirus which has become a major cause of lost egg production and sever economic losses in breeder and layer chicken flocks throughout the world. A PCR assay was optimized for detection of EDS virus in inoculated allantoic fluids (AFs) of duck and chicken emberyonated eggs. Two strains of EDS viruses were propagated in allantoic cavit...

To prepare hemagglutination inhibition (HI) antigen the egg drop syndrome virus (EDSV) was propagated in 10-day-old embryonated duck eggs. The virus antigen was inactivated with two methods including heating (65°C) and adding 0.5% formaldehyde by considering low destroying effect on hemagglutination (HA) and HI titers. The EDSV HI titers of 310 sera and 100 yolks obtained from 23 chicken farms ...

Egg Drop Syndrome 1976 (EDS76) is a viral disease of laying birds characterized by a sudden drop in egg production, failure to achieve peak production and the laying of poor quality eggs. It has been reported to affect a wide range of birds including turkeys and layers and is a major constraint to the profitability of egg production in both commercial and village laying birds. This paper is a r...

A drop in egg production associated with loss of pigment and soft-shelled eggs was experienced on a farm in the Western Cape. Investigations revealed high levels of antibodies against adenovirus 127, the causative agent of egg drop syndrome (EDS) in chickens which were not vaccinated against EDS. A cytopathic agent was subsequently isolated in chicken embryo liver cell cultures and identified a...
