| Abstract: | Channel catfish, Ictalurus punctatus , were immunized with cilia from three isolates of Tetrahymena pyriformis and challenged with Ichthyophthirius multifiliis using a reproducible quantitative procedure. Two different methods of deciliation were used in antigen preparation. Results indicate that T. pyriformis cilia elicit an immune response in channel catfish against I. multifiliis , and that the protective ability of the cilia varies between T. pyriformis strains. |
