Fig. 4From: Synergistic effect of combination chemotherapy with praziquantel and DW-3-15 for Schistosoma japonicum in vitro and in vivoScanning electron micrographs of S. japonicum males of the negative control group. Worms after 72 h of incubation showed no abnormalities in tegument topography or the gynecophoral canal (GC) (a). Notably, the morphology of the oral and ventral suckers was normal, showing high integrity and prominent spines (S) (b, c). Numerous tegumental crests (TC) with sensory papillae (SP) appeared along the body (d–f). Scale bars: a, 50 µm; b, 5 µm; c, 4 µm; d, 10 µm, e, 10 µm, f, 2 µmBack to article page
