The onchocerciasis parasite showing signs of resistance

Onchocerciasis is an infection caused by Onchocerca volvulus, a parasite nematode worm transmitted to humans by a species of black fly of the Simulium genus whose larvae develop in fast-flowing rivers. Infected subjects suffer not only from severe skin lesions but also eye damage that can lead to irreversible loss of sight, hence the name ‘river blindness’.
