Scientists uncover hidden parasite diversity in barb fish from the Sea of Galilee

Phys · · 982 words · By Aditya Gupta

Researchers led by Dr. Aditya Gupta identified two new species of microscopic parasites, Myxidium grauri and Myxidium sharmai, in barb fish from the Sea of Galilee. The study utilized DNA sequencing to distinguish these species from others that appear morphologically identical, highlighting the importance of molecular tools in understanding freshwater biodiversity.
