Abstract

Domestic animals, as bovine and equine, are vulnerable to diseases caused by infectious pathogens. Unfortunately, the pathogens that infect animals can also infect humans. In this context, the public health demands a global effort to control zoonotic diseases in herds from developing countries. Serology tests are applied to diagnose the infected animals, protect the human population and implement the disease control procedures. Among the reagents used in diagnostic platforms, the antibodies, as the Immunoglobulin G (IgG) and IgY from mammals and chickens, respectively, are some of them. The IgY antibodies are available in egg yolk content from immunized chicken. According to the principles of welfare, the large amount of antibodies and the antigenic target recognition made IgY an alternative biologic reagent in veterinary diagnosing tests. Innovative platforms for serology assays are being produced using IgY-technology.
