Detection of Chicken Infectious Anemia Antibodies and Their Relationship with Other Immunosuppressor Virus in Broilers Chicken. Zulia State, Venezuela. ABSTRACT The incidence of viral respiratory and immunosuppressant diseases are two of the biggest problems in the Venezuelan poultry industry, however in the country, there is not enough epidemiological information that helps to establish control measures. The aim of this research was to determine the presence of serological chicken anemia virus, reovirus and gumboro, and it´s correlation between them as well as to determine the level of anemia in the evaluated birds. In this research, approximately fourteen or fifteen (14 or 15) birds were tested weekly and at different ages (1; 7; 14; 21; 28; 35 y 42 days), in three commercial farms. The samples were taken from a total of 295 birds. The viral antibodies were determined by ELISA test and the anemia levels by micro-hematocrit. The presence of seropositivity was 90.8% (268/295) for the chicken anemia virus, 82.4% (244/295) for reovirus and 97% (286/295) for gumboro. Of the total, 9.6% (58/295) of the evaluated birds presented anemia, showing values of hematocrits between 20% and 27%. A positive correlation was found between chicken anemia virus and the other immunosuppressor viruses studied, gumboro (r=0.437; P<0.0001) and reovirus (r=0.312; P<0.0001). The obtained results in this research demonstrated the presence of viral anemia, in broilers, in the Zulia Region, with or without the presence of reovirus and/or gumboro. That could have an effect, in either sub-clinical or clinical forms.
