  Immune response of sonicated coccidiai oocyst was observed in chickens. Indirect haernagglutination (INA) test was developed for detecting antibodies to coccidia and serum antibody levels were measured against soluble oocyst (sporulated) antigen. IHA antibody titre was significantly higher (p<0.05), in chicks vaccinated with inactivated sonicated vaccines as compared to the chicks vaccinated with inactivated sporulated vaccine. The IHA antibody titre vaccinated with inactivated sonicated vaccine ranged from 1 : 64 to 1 : 1:512, among the 15 samples processed, 1:64 in two samples, 1:128 in four samples, 1: 256 in seven samples and 1: 512 in two samples. It gave 100 percent protection to the challenge chicks. Their faeces were normal and no clinical sign was recorded even 40 days post vaccination.

  A splenic cell migration inhibition test with modifications was successfully employed in the flat bottom micro titration plates to detect the cell mediated immunity more conveniently and accurately due to vaccine against coccidiosis. A drop of melted agarose (0.2% in PBS) was used to immobilize the splenic fragments. The splenic cells were culture in Hank`s Balanced salt containing fresh chicken plasma and maintained for 10 days. Twenty four hours after cultivation, dominant cell type migrated from a splenic fragment was leukocyte-like cells. At the fourth day these appeared predominantly large round cells and resembled to the macrophage. At the 10th day, spindle cells resembling of fibroblast appeared. The migration of the splenic cells from immunized chickens were inhibited remarkably with the antigen and there was a significant difference (P<0.01) in migration distance of the splenic cells with and without the antigen.
