Abstract
Attempts were niade to establish experimental infection in dogs. In this study , the best method was to mix the hydatid cysts fluid from camel with milk at ratio ice. of cystic fluid per JO cc.milk and to be given to young dog (l—6months).
The prepatent period of the infected dogs varied from 56 to5a days. Variation in this prepatent period iaa attributed to methods of storage oZ cysts in the laboratory. In experimentally infected dogs with ]chinococcus, the worms became senile and showedagreat reduction in egg production as early as four to five months after infection of the final host . The intestine became free from worms at seven months post infection.
No clinical symptomes were observed in experimentally infected dogs. Post mortem examination revealed that at 36 to 3a days, the small intestine was heavily infected with worms and the mucous membranes were coated with mucous secretion. The capillaries supplying the small intestine were congested with blood.
It was intended in the present investigation to Infect the laboratory aniaals ( rat, mice and rabbit) with the
