The protective role of Fasciola tegument antigen against Trichinella spiralis infection.

Fasciola gigantica tegument antigen was prepared to be used for induction of immunity against Trichinella spiralis in albino mice. The results of the study showed that the antigen was more effective when administered in a dose of 3 micrograms than in a dose of 30 micrograms. This was evidenced by the reduction in adult count 72%, adult length 61.4%, larval count 78.7%, length of muscle larvae 32.2% and the significant reduction in reproductive capacity index.
