Abstract/OtherAbstract:
1. Early granulocytic response was evaluated in chick embryos inoculated with herpesvirus of turkeys (HVT). 2. Fifty 10-d-old specific pathogen-free embryos were divided into two groups, inoculated via yolk sac. Group 1 were inoculated with a complete dose of HVT and group 2 with vaccinediluent only. 3. Samples were taken for histological evaluation of yolk sac, liver, chorioallantoic membrane, brain and heart from 5 embryos per group on days 12, 14, 16, 18 and 20 of embryonic life. 4. Increases in numbers of granulocytes were detected on days 14 and 16 in the yolk sac, and on d 14 and 20 in the liver of in embryos, which received HVT. In addition, the chorioallantoic membrane was infiltrated with granulocytes. 5. The results confirm that granulopoiesis in the yolk sac is stimulated in the early stages of incubation if a viral antigen is present. The virus also appears to trigger the presence of granulocytes in embryonic liver and chorioallantoic membranes.
