Which nematode causes “Naru bala” disease in humans?

✅Explanation:
"Naru bala" (also known as Guinea worm disease or dracunculiasis) is caused by the nematode Dracunculus medinensis. This parasite is transmitted to humans through contaminated drinking water containing infected copepods (small crustaceans). The adult female worm emerges from the skin, causing painful blisters, usually on the lower limbs.
