Viability of adult Schistosoma mansoni worms after exposure to hydrogen peroxide.

(A) Number of adult worms after 24-hour exposure to increasing concentrations of hydrogen peroxide (H₂O₂). (B) Number of adult worms after 24-hour exposure to increasing concentrations of H₂O₂ in the presence of HUVECs. Worm viability was categorized into four scores: score 3 (intact tegument and active motility), score 2 (partial tegument damage and moderate motility), score 1 (darkened tegument and low motility), and score 0 (complete loss of motility and tegument integrity, indicating death).
