Synergistic action of praziquantel and host specific immune response against Schistosoma mansoni at different phases of infection Ação sinergística do praziquantel e resposta imune específica do hospedeiro ao Schistosoma mansoni em diferentes fases da infecção

The interaction between specific immune response to Schistosoma mansoni and praziquantel (PZQ) was studied in mice. In mice harboring concomitant immunity, 6-day-old parasites treated with PZQ were more effectively removed than 24h treated parasites despite both had a significant worm burden reducti...
