Schistosomoses
Objectives
After this unit, students should be able to: 1. Relate the etiological agents of schistosomiasis, their developmental stages and the induced pathology in humans. 2. Understand the host-parasite-environmental dynamics in the scope of schistosomiasis expansion. 3. Be aware of bioinformatics application tools in schistosome research. 4. Select and apply molecular methods in the diagnosis of schistosomiasis. 5. Consider preventive measures in the emerging scenario of drug-resistant schistosmes. 6. Intervening factors in the epidemiology and transmission of helminths. 7. Propose the adequate measures for planning and monitoring a schistosomiasis control programme.
