Scientists at the University of Liverpool have found that the worm which causes River Blindness survives by using a bacterium to provide energy, as well as help 'trick' the body's immune system into thinking it is fighting a different kind of infection.

It is caused by a parasitic worm that is transmitted by blood-feeding blackflies, which breed in fast-flowing rivers.To see more details visit,www.medicalnewstoday.com/
