  Delayed hypersensitivity reaction was used to measure the cell mediated immunity against avian coccidiosis. There was a gradual increase in the comb thickness of the immunized birds of all the groups from 24 to 72 hours after intradermal injection. The mean difference in comb thickness before and after injection of the respective antigen for the group immunized with Vaccine I (sonicated supernatant) was 1.87 mm at 24 hours, 2.23 mm at 36 hours, 2.31 mm at 48 hours and 2.42 mm at 72 hours. There was a significant difference (p<0.01) in comb thickness at 24 and 36 hours after intradermal injection. The mean difference in comb thickness before and after injection of the respective antigen for the group immunized with Vaccine II (sonicated sediment) was 1.12 mm at 24 hours, 1.75 mm at 36 hours, 2.10 mm at 48 hours and 2.31 mm at 72 hours. The difference was significant (p<0.01) at 24 and 48 hours; 36 and 72 hours after injection. Maximum difference in comb thickness was recorded 72 hours after injection in birds immunized with Vaccine I. It appears that delayed hypersensitivity response to sonicated supernatant antigen reported herein represent a strong CMI reaction. Delayed hypersensitivity comb reaction is a quick, simple, economical and practical tool to routinely determine the immune status of a bird with out restoring to challenge.

  Immune response of formalin inactivated and binnary ethyleneimine inactivated Angara disease (hydropericardium) vaccines were compared using indirect hemagglutination (IHA) test. A four fold increase in IHA antibody titre was recorded with binnary ethyleneimine (BEI) inactivated vaccine. Agar gel diffusion test gave a strong precipitation line with serum of chicks vaccinated with BEI inactivated vaccine whereas a weak precipitation line was observed with serum from chicks vaccinated with formalin inactivated vaccine. The results of challenge test were promising and no adverse effects were seen in vaccinated chicks. BEI as inactivating agent produced antigenically superior vaccine.
