| Abstract | ||
| immunity system to obtain immunization against helminthiasis . The larvae at different stages of mechanical hatching have been used as antigens . The ovulation – hatching fluid has also been used as another antigen for the immunologic stimulation . It has been found that the extracts of both types have the capability of stimulation of immunity system and protection from Ascaris mature ova infection . The number of extracted larvae taken after administered infection dose is used to induce the antigen – immunization . The study has revealed the following findings :- 1. Reduction in larvae no. Extracted from immunized mice with larvae extract . The protection rate obtained from injected mice intraperitonealy (IP) was 78% and 66% from those injected intramuscularly (IM) in contrast with the control group 2. Reduction in larvae no. Extracted from immunized mice with ova-hatching fluid . The protection rate obtained from injection mice (IP) was 31% and 59% for those injected in the muscles (IM) in contrast with the control group . 3. Both antigens from protection against helminthiasis for their hosts by different rates . | ||
