Schistosoma mansoni: implante de vermes na cavidade peritoneal visando imunoproteção

Schistosoma mansoni: implantation of worms into the peritoneal cavity aiming at the induduction of immunoprotection

Resumos

Tentou-se obter imunoproteção contra infecção cercariana pela inoculação de vermes vivos na cavidade peritoneal de camundongos. Embora os vermes sobrevivessem bem nestas condições e não ocorresse postura de ovos, não foi possível obter imunoproteção, Também a inoculação de ovos viáveis por via sangüínea e peritoneal não propiciou o aparecimento de imunoproteção nos camundongos com vermes na cavidade peritoneal.

An attempt has been made to induce immunoprotection against cercarial infection through inoculation of live worms into the peritoneal cavity of mice. Although the worms were able to survive normally under these conditions, and no egg-laying could be detected, immunoprotection was obtained. Likewise, the inoculation of viable eggs, by circulatory and peritoneal routes, did not provide immunoprotection in mice with worms in the peritoneal cavity.
