Based on serology and virus isolation of chicken flocks, chicken anemia virus (CAV) is present worldwide.

CAV was first isolated in 1979 in Japan. Since then, an increasing interest was paid to this virus, as it was found to have a great impact on poultry industry in all major chicken-producing countries of the world. CAV is an immunosuppressive agent causing economic losses by inducing poor general performance and interfering with the immune response to vaccines. Based on the clinical or subclinical CAV infection on immune response, the infection has been related to increased susceptibility to other agents such as infectious bursal disease virus (IBDV). In addition, presence of CAV antibodies at slaughter has a substantial and significant negative effect on the broiler performance and profitability.

The most effective method to control the disease is to vaccinate breeder flocks before the onset of lay. In order to guarantee effective protection against CAV, parent flocks must have high and uniform antibody levels throughout the whole laying period. Currently, there are several CAV live vaccines available with CAV vaccine strains of different attenuation levels which present different immunogenic properties. Combination of vaccination and monitoring of CAV antibody titers in breeders and their progeny ensure effective protection against CAV and decreases the economic losses.

Register at to attend a one-hour educational webinar, “Optimizing the protection against chicken infectious anemia,” sponsored by Lohmann Animal Health and presented by WATT Global Media, to learn about the effects of CAV infection on other pathogens, the best strategies to prevent CAV-induced immunosuppression and the new tools for monitoring the immunization programs. The webinar will be held November 12, 2014, at 13:00 GMT.


Poultry veterinarians and nutritionists, research and development and operations directors, production managers, farmers, producers, purchasing directors, and commercial directors in poultry integration should attend to learn:

  • Why an optimum prevention against CAV may improve your profitability
  • What are the best vaccination strategies to reduce health problems associated with CAV
  • Which are the new tools for monitoring the CAV vaccination programs


Alejandro Banda will be the speaker for this webinar.

Banda is a clinical professor in veterinary virology with the Department of Pathobiology and Population Medicine, College of Veterinary Medicine, Mississippi State University. He obtained his Doctor of Veterinary Medicine, and Master of Science degrees from the National Autonomous University of Mexico (UNAM). In 2002, he obtained a Ph.D. in medical microbiology at the University of Georgia. From 1995 to 2004 he served as an associate professor in avian medicine at the College of Veterinary Medicine at the UNAM, and from 2004 to 2008 he served as an extension associate and laboratory director at the Cornel University Duck Research Laboratory in Eastport, NY. He is a diplomate of the American College of Poultry Veterinarians (ACPV), and the American College of Veterinary Microbiologists (ACVM). His professional and academic interests are focused on avian medicine, classical and molecular diagnostic veterinary virology, serological methods, and to the study of immunosuppressive diseases of poultry. Banda has published several papers in peer-reviewed journals and scientific book chapters.
