Abstract

In an effort to develop an effective and affordable oral vaccine against porcine Taenia solium cysticercosis, the S3Pvac anti-cysticercosis vaccine was expressed in papaya calli. Taenia pisiformis experimental rabbit cysticercosis was used as a model to compare the efficacy of the oral vaccine vs. the injectable S3Pvac-synthetic and S3Pvac-phage versions.Oral S3Pvac-papaya significantly reduced the expected number of hepatic lesions and peritoneal cysticerci to a similar extent than the injectable vaccines. This study reports for the first time an effective oral vaccine against T. pisiformis cysticercosis, possibly useful against porcine T. solium cysticercosis.

► S3Pvac synthetic, S3Pvac-phage, S3Pvac-papaya protects against rabbit cysticercosis. ► Parenteral S3Pvac induced high similar protection than oral S3Pvac-papaya vaccine. ► S3Pvac components are expressed in Taenia pisiformis cysticerci and in oncospheres. ► Vaccination increased the inflammatory reaction surrounding established cysticerci.
