ABSTRACT
This study includes effect of Immunizaton by intrapertoneal inoculation of unembryonated eggs, embryonated eggs , died larvae , live larvae and excretory / secretory products of larvae (L2) of T.canis and T.leonina to protect white mice (Balb/c) from the experimental infection by T.cati and T.leonina the results showed that the highest rate of protection is 69. 56% then , 68.77%, 65.83% , 65.20% and 55.70% when the mice immunized by excretory/ secretory products, Live Larvae, died Larvae, embryonated eggs and unembryonated eggs of T.canis antigens against the challenge dose of T.cati the highest protection rate against the experimental infection with T.leonina was obtained by inoculation of live larvae of T.leonina (58.63%) by using a challenge dose same to the immunization dose. while the highest protection rate obtained by T.canis against the experimental infection with T.leonina was obtained by immunization with live larvae(54. 74%).
