Technical Abstract: This study compares the immune response of Nile tilapia and red tilapia against parasite Ichthyophthirius multifiliis (Ich) using a cohabitation challenge model. Both Nile and red tilapia showed strong immune response post immunization with live Ich theronts by IP injection or immersion. Blood serum from immune Nile or red tilapia contains anti-Ich antibody which caused infective theronts ceasing swimming, forming theront aggregate and reducing theront infectivity. This study helps to understand the immune response of Nile and red tilapia and assists in development of vaccines against parasite Ichthyophthirius.
