Egg Drop Syndrome
Egg Drop, EDS
Egg drop syndrome (EDS) is a disease affecting domestic laying hens, caused by an atadenovirus. The virus is believed to have originated in ducks and other waterfowl, who are often infected with the virus but show no clinical signs of disease. Heavier broiler-type breeds and brown egg producing chickens are most severely affected by the disease.
Symptoms of Egg Drop Syndrome
Often, the first sign of infection is a change in the color of the egg, quickly followed by production of smaller-the-normal eggs, shell-less, thin-shelled, or soft-shelled eggs, and either a rapid or extended loss in egg production of up to 40%. Clinical signs are mainly associated with egg production.
Diagnosis of Egg Drop Syndrome
The sensitivities of various serologic assays, including agar gel precipitin (AGP) assay, ELISA, Hemagglutination-inhibition (HI), and serum neutralization, are similar for detecting antibodies to EDS virus.
