Effects of one-day exposure to amodiaquine (AQ) and praziquantel (PZQ) on the gross appearance of Schistosoma mansoni adult worm pairs. Paired adult worms were incubated drug free (control) or with 10 μg/ml AQ or 0.1 μg/ml PZQ on the first day and subsequently incubated with daily replacement of drug-free media on the other days. The male and female signs indicate male and female worms, respectively. Small and large arrows show the localization of hemozoin in female worms and the swelling in male worms, respectively.
