    Five exposures of baboons to the attenuated schistosome vaccine gave greater protection than three exposures, but this attenuation was not sustained when challenge was delayed. Within the scope of the data collected, fecal egg counts and circulating antigen levels did not accurately predict the observed worm burdens. Levels of immunoglobulin G at challenge correlated best with protection, but there was little evidence of a recall response

    To identify any toxicity on the vaginal epithelium, liver and kidney following UniPron administration, ten healthy female olive baboons ( Papio anubis ) of reproductive age and of proven fertility were used. Five baboons were each treated with 15g of UniPron intravaginally twice a week for 20-weeks and venous blood collected before and after each treatment. Venous blood was collected from five control animals as in the experimental females, but these control animals were not given any treatment. The endpoints that were evaluated included clinical chemistry profiles on kidney and liver functions and vaginal histopathology. Female baboons treated with 15g of UniPron intravaginally showed no detectable adverse effects on clinical chemistry profiles investigated and vaginal histopathology. Repeated intravaginal exposure of female baboons to UniPron did not induce detectable vaginal irritation and there were no detectable histological changes. We conclude that administration of UniPron into baboon vagina did not cause any detectable toxicity (Afr J Reprod Health 2009; 13[4]:95-104).Pour identifier la prĂ©sence de la toxicitĂ© sur l’épithĂ©lium vaginal, la foie et le rein suite d’une administration d’UniPron, nous avons utilisĂ© dix babouins ( Papio anubis ) olivĂątres en bonne santĂ© qui Ă©taient en Ăąge de procrĂ©er et d’une fĂ©conditĂ© confirmĂ©e. Cinq babouins ont Ă©tĂ© soignĂ©s chacune au 15g d’UniPron par voie intravaginale deux fois par semaine pendant 20 semaines et le sang veineux a Ă©tĂ© collectĂ© avant et aprĂšs chaque traitement. Le sang veineux a Ă©tĂ© collectĂ© de cinq animaux tĂ©moin comme dans le cas des femelles d’expĂ©rience, mais ces animaux tĂ©moin n’ont pas Ă©tĂ© traitĂ©s. Les rĂ©sultats qui ont Ă©tĂ© analysĂ©s ont compris les profils chimiques clinques sur les fonctions de la foie et du rein et l’histopathologie vaginale. Les babouins femelles qui ont Ă©tĂ© soignĂ©es au 15g d’UniPron par voie intravaginale n’ont pas eu d’effets nĂ©gatifs dĂ©tectables sur les profils chimiques Ă©tudiĂ©s et sur l’histopathologie. L’exposition intravaginale rĂ©pĂ©tĂ©e des babouins femelles a UniPron n’a pas dĂ©clenchĂ© l’irritation vaginale dĂ©tectable et il n’y avait pas de modifications histologiques dĂ©tectables. Nous avons conclu que l’administration d’UniPron dans le vagin du babouin n’a causĂ© aucune toxicitĂ© dĂ©testable (Afr J Reprod Health 2009; 13[4]:95-104)
