Morphological changes of Echinococcus granulosus following In vitro treatment with tetraspanin1 (EgTSP1)-specific dsRNA. Different development stages, protoscoleces (PSC, left column), one-proglottid worms (SW1, middle column) and three or more proglottids worms (SW3, right column) were treated by the dsRNA using electroporation (a, b, c), and electro-soaking (d, e, f) as compared to the irrelevant dsRNA (g, h, i) and untreated controls (j, k, l). Note the outer layer irregularities and malformations (arrowheads) in the tegument of protoscoleces (PSCs) and strobilated worms (SW). Scale-bars: 200 μm
