Helminthology

This course provides a comprehensive overview of helminthology, focusing on parasitic helminths and essentials of parasitic arthropods. It explores the evolution of parasitic associations, classifications, morphological characteristics, and life cycles of trematodes, cestodes, and nematodes. Students will learn about soil-transmitted helminths, blood and tissue nematodes, and the biological significance of parasitic helminths, including their modes of transmission and economic importance. The course also covers parasitic arthropods and their impact on human health.
