Clinical signs in people correlate with the life cycle of the parasite and are associated with the parasitic form: cercariae (cercarial dermatitis), schistosomula (producing symptoms such as cough and fever), adult worm (rarely pathogenic), and eggs (causing Katayama fever and schistosomiasis).
Mice infected with 50 cercariae (BH strain) were intraperitoneally treated at a dose of 50 mg/kg for 5 consecutive days, starting on the 1st, 14th, 28th and 45th days after infection, to evaluate the effect of [beta]-lap on skin schistosomula, lung schistosomula, young worms (before oviposition) and adult worms (after oviposition), respectively.
