Shell-less, soft-shelled, and thin-shelled eggs are all characteristics that point to EDS ridged and misshapen eggs are not. Similar diagnosis diseases of the EDS virus include failure to achieve adequate egg production levels or if there is a decrease in egg production in seemingly healthy birds. Once of the easiest alternative methods is to feed affected eggs to antibody-free hens. It is important to select recently infected birds for testing, but these can be difficult to identify. PCR-based tests and antigen capture ELISA tests have been used to detect EDSV DNA and antigens. In addition, a hemagglutination-inhibition test using fowl RBCs, and ELISA, are the primary serologic tests of choice. Searching for evidence of seroconversion is the easiest diagnostic approach for nonvaccinated flocks. With endemic or sporadic EDS '76, the disease can develop in laying hens of any age.Ĭonfirmatory laboratory testing is needed for definitive diagnosis. Poor eggshell quality at peak production in healthy hens should also raise strong concerns for EDS '76. Ridged eggs and poor internal quality are not features of EDS '76. Transient mild depression and/or mild watery droppings may be seen. Production of pale thin-shelled and shell-less eggs by a flock that appears otherwise healthy suggests that EDS '76 is present. Birds with antibodies slow the spread of the virus throughout the flock. In flocks in which there has been some spread of virus and antibodies are present, the condition is seen as a failure to achieve predicted production targets. Birds tend to eat the thin-shelled and shell-less eggs. The first sign of the disease is the production of pale-shelled eggs, followed by the production of soft-shelled and shell-less eggs. The third pattern is sporadic and due to spread of EDS virus due to contact with domestic or wild ducks or geese or the use of a water supply contaminated with wildfowl droppings. It is usually seen in commercial egg layers. The second pattern is seen through endemic EDS, which is the result of horizontal infection of the flock during lay. Then, the virus multiply and are excreted in the eggs and fecal matter. The chicks that hatch are contaminated with the virus which remains latent until the birds reach sexual maturity. The first pattern with EDS ‘76 occurs when primary breeding stock are infected, and the virus is transmitted vertically through the egg. There are three patterns of viral transmission recognized in chickens. All ages and breeds of chickens are susceptible to infection. OccurrenceĮDS ‘76 has been recently reported in the US and in many other countries such as Ireland, England, and Brazil. Infection rate is lost after treatment with 0.5% formaldehyde or 0.5% glutaraldehyde. The EDSV is resistant to pH range 3–10 and to heating for 3 hours at 56☌ (approx.132.8☏).
