Enhanced pathogenicity of chicken anemia agent by infectious bursal disease virus relating to the occurrence of Marek's disease vaccination breaks



Enhanced pathogenicity of chicken anemia agent by infectious bursal disease virus relating to the occurrence of Marek's disease vaccination breaks



Japanese Journal of Veterinary Science 51(4): 849-852



SPF chicks were inoculated i/p with 0.1 ml of chicken anaemia agent 82-2 or orally with 103.5 EID50 of infectious bursal disease virus strain GBF-1, or with both agents simultaneously, at 14, 21 or 28 days of age. In a second experiment, day-old chicks were inoculated s/c with 2200 pfu of turkey herpesvirus strain H2, and vaccinated and unvaccinated chicks challenged i/p with 2700 pfu of virulent Marek's disease virus, JM strain, at 7 days of age. Vaccinated and MDV-challenged chicks were inoculated with CAA and IBDV at 14, 21 or 28 days of age as in experiment 1, or left uninoculated. Chicks were reared to 70 days of age. In HVT-vaccinated and MDV-challenged chicks, an early mortality syndrome occurred at a relatively high frequency when both CAA and IBDV were inoculated at 14 or 21 days of age, and that simultaneous inoculation with both agents significantly depressed HVT vaccinal immunity. CAA and IBDV are known to be widespread in commercial chicken flocks in Japan. It is suggested that chicks may become infected with both agents around 3 weeks of age, when maternal antibody titres have decreased and that this may result in MD vaccination breaks.
