Abstract

The study included the effect of intramuscular injection of white mice (Balb/c) with unemberyonated eggs emberyonated eggs, dead larvae, live larvae and excretory secretory products of in-vitro cultured larvae of dogs ascaris to immunize white mice against the experimental infection by cat Ascaris.
The results showed that the highest reduction rate in the number of larvae is 65.08% then 62.79% , 61.60%, 61.09% finally 61.05 when give the excretory secretory products live larvae, unemberyonated eggs, dead larvae and emberyonated eggs, respectively.
The better antigen against experimental infection by T.leonina is the live larvae of the same worm (52.68%) , the live larvae of T.canis ( 51.15%).
