Immunization Of Rats Against Mesocestoides Corti (Cestoda) By Subcutaneous Vaccination Of Living Tetrathyridia And By Passive Transfer With Serum, Jerry Y. Niederkorn
Journal of the Arkansas Academy of Science
Laboratory rats were subcutaneously vaccinated with 100 live tetrathyridia of Mesocestoides corti (Cestoda) and subsequently intraperitoneally challenged with 50 tetrathyridia. Necropsy 30 days postinfection revealed that vaccinated rats harbored 97.4% fewer worms compared to control rats. In a second experiment, passive transfer of immunity was accomplished by immune serum from subcutaneously vaccinated rats. Rats receiving immune serum harbored 33.4% lighter worm burdens compared to normal serum recipients.
