“…Concerning the digeneans, the studies included larval and adult forms: larval forms such as larval stages of Schistosoma mansoni (Bruckner and Vage 1974), cercaria of S. mansoni and Schistosoma japonicum (Orido 1989), cercaria of Diplostomum pseudospathaceum (Niewiadomska & Moczon 1982), daughter and mother sporocyst of D. pseudospathaceum (Niewiadomska & Moczon 1990), and sporocysts of S. mansoni (Diconza & Basch 1975) and adult forms, such as S. mansoni (Fripp 1967), Fasciola hepatica and Fasciola gigantic (Prcbert and Durrani 1976), Gorgoderina vitelliloba (McKAY et al 1991), G. vitelliloba and Gorgoderina euzeti (Rahemo 1993), and Haplorchoides cahirinus and Acanthostomum absconditum . The aim of this study is to describe the nervous system of both S. mansoni and Schistosoma haematobium for the first time in detail, using acetylthiocholine iodide enzymatic technique.…”
