Abstract
Schistosomiasis is an important parasitic disease, touching roughly 200 million people worldwide. The causative agents are different species. Schistosoma Schistosomes have a complex life cycle, with a freshwater snail as intermediate host. After infection, sporocysts develop inside the snail host and give rise to human dwelling larvae. We present here a detailed step-by-step video instruction in English, French, Spanish and Portuguese that shows how these sporocysts can be manipulated and transferred from one snail to another. This procedure provides a technical basis for different types of modifications, ex vivo such as those used in functional genomics studies.
