▬ 📌 Tissue Helminths
Helminths are one of the leading causes of morbidity in developing countries and affect almost 2 billion people every year, which is almost a third of the World’s population!

In this video, we are discussing different diseases and organisms associated with them.
🔹 Schistosomiasis
🔹 Clonorchiasis
🔹 Filariasis
🔹 Onchocerciasis

Learn the details of the bacteria along with the life cycle, important properties, pathogenesis, epidemiology, treatment, and prevention.

▬ 📌 Schistosomiasis
