Effect of oxamniquine on cell adhesion to Schistosoma mansoni larvae in the peritoneal cavity of naive mice

Efeito da oxamniquina sobre a adesão celular da larva do S. mansoni na cavidade peritoneal de camundongos

Abstracts

The treatment of naive mice with high closes of oxamniquine, 1 hour before the intraperitoneal inoculation of Schistosoma mansoni cercariae, induces a delay in the transformation process resulting in a longer host cell adhesion.

Schistosoma mansoni; Cell adhesion; Cercaria; Schistosomulum; Oxamniquine


O tratamento de camundongos sem infecção prévia com altas doses de oxamniquina, 1 hora antes do inóculo intraperitoneal com cercárias de Schistosoma mansoni, induz a um atraso no processo de transformação, resultando conseqüentemente em larvas com adesão celular mais duradoura.
