Abstract Background Chicken anemia virus CAV is the causative agent of chicken infectious anemia CIA . Study on the type of CAV isolates present and their genetic diversity transmission to their progeny and level of protection afforded in the breeder farms is lacking in Malaysia. Hence the present study was aimed to detect CAV from commercial broiler breeder farms and characterize CAV positive samples based on sequence and phylogenetic analysis of partial VP1 gene. Results A total of 12 CAV isolates from different commercial broiler breeder farms were isolated and characterized. Detection of CAV positive embryos by the PCR assay in the range of 40 to 100 for different farms indicated high level of occurrence of vertical transmission of viral DNA to the progeny. .
