THE EFFICIENCY OF IMMUNIZATION WITH SERUM AND SPLEEN CELL OF MICE WITH ANTIGENS SENSITIZED OF TOXOCARA CANIS AND TOXASCARIS LEONINA AGAINST INFECTION WITH TOXOCARA CATI AND TOXASCARIS LEONINA LARVAE

Abstract

The study reveals the effect of immunization of white mice (Balb/ c) with sensitizedserum and spleen cell of mice with of whole eggs extract and excratory secretory products of larvae of T.canis, T. leonina to protect mice from the larvae of T. cati, T. leonina infestation.Results showed that thehighest percentages of protection mice from T. leoniua 61.46%, 59.55% and 52.86% when miceimmunized with egg, Whole extract and were excretory secretory products of T. canis respectively. Thehighest percentages of protection from T. leonina larvae were 51.83%, 51.04% when immunized withegg, excretory secretory product of T. leonina antigen. Immunized mice with spleen cell .The highest ofpercentages of protection were 65.10%, 60.06%, 54.36% against T. cati larvae when immunized witheggs, whole extract, excretory and secretory products of T. canis respectively the highest percentage ofprotection from T. leonina larvae 54.07%, 52.34% when immunized mice with egg and whole exctract ofT. leonina and 53.33%, 50.12% when immunized mice with whole
