Abstract :

Chicken infectious anemia virus, which causes aplastic anemia, extensive lymphoid tissue athtrophy, along with immunesuppresstion , provides the basis for secondary viral, bacterial, and fungal infections, and Transmitted vertically from the breeder flocks to the chickens. The virus can cause severe Economic losses. In the present study, the simultaneous contamination with chickens infectious anemia virus (CIAV) and respiratory complexes diseases in broiler flocks of Shooshtar and Bavi cities was studied by hematocrit and pathology method. In this study During the 6 month period, the farms of poultry that showed symptoms of respiratory complex diseases were selected. Twenty flooks sampled for whole blood samples, thymus tissue, bursa fibersius, and bone marrow and tested for Hematocrit and histopathology. Results of hematocrit tests were normal in 95% of the flooks, while among the tested flooks, 50% of the tissue samples showed histopathological lesions associated with infection of the chickens infectious anemia virus. The results of the present study show that the simultaneous contamination rate with chickens infectious anemia virus and respiratory complexes diseases is high in 50% of the studied poultry population. Pathological results, indicates that infection rate of this virus is high in industrial broiler population of the region and causing economic losses.
