Abstract

Molecular characterization of the chicken anemia virus by using the VP1 gene of CAV/ SK/2017 strains, Iraq ABSTRACT Chicken infectious anemia virus (CIAV) is one amongst the numerous pathogens in the poultry industry. CIAV infection can cause restraint of the immune system, the excitement of co-infections, vaccination failures and mortality. chicks. Maternal antibodies not prevent infection but to prevent these symptoms, immunological disorder, or transmission of the virus. Genetic characterizations for five sequences of chicken infectious anemia virus (CIAV) from different flocks of broiler industrial chickens were a consideration for the primary time in Iraq. Phylogenetic analysis of the viral protein 1 (VP1) gene, as well as the hypervariable region of the CIAV genome, indicated that Iraqi CIAV strains have belonged into genotype II. Amino acid comparison exhibit that the diversity of VP1 is indicated that the new strains were extremely pathogenic viruses. Our epidemiological study provided new insights into the prevalence of CIAV strain in recent years in Sulaimani province/Iraq.
