River Blindness, scientifically called onchocerciasis, is a skin and eye disease transmitted by Onchocerca
volvulus, a parasite that can cause permanent blindness.
2 It is caused by the parasitic worm Onchocerca
Several types of parasitic roundworms have iPGM, including Brugia malayi and Onchocerca
volvulus, which infect roughly 150 million people living mostly in tropical regions.
Deep ear scrapings were obtained from pinna which were mixed with normal saline teased with dissecting forceps and examined under light microscope immediately after collection for presence of skin microfilariae (Stephanofilaria and Onchocerca
species) (Soulsby, 2005).
Algumas especies da familia Simuliidae apresentam competencia vetorial para transmitir especies de nematoides dos generos Onchocerca
, Mansonella, Splendidofilaria e Dirofilaria, motivo pelo qual apresentam grande importancia medica e veterinaria.

Intraocular nematode infections are uncommon and usually caused by filarial worms such as Loa loa and Onchocerca
volvulus that are transmitted by flies in the tropics.
Simulium guianense Wise (Diptera: Simuliidae) is widely distributed in Brazil (Adler & Crosskey 2014), but it is more frequent in the northern portion of the country where it is the main vector of the nematode Onchocerca
volvulus (Leuckart) (Spirurida: Onchocercidae) in the Amazon region.
Although these species have not been incriminated in transmission of Onchocerca
volvulus, the high density of the population and their severe biting cause negative impact on human population (allergy) and on cattle (loss of weight and/or reduction of milk production) (MARCONDES, 2011).
Caused by the parasite onchocerca
volvulus, river blindness is the second-leading infectious cause of blindness in the world and is transmitted to humans via the bite of a certain species of black fly that is commonly found near rivers.
Currently, they have added genome sequencing of wBm and Onchocerca
volvulus (Ov) with the Sanger Institute, NEB and TIGR.
River blindness, also known as Ochocerciasis is an eye and skin disease caused by a tiny worm called onchocerca
volvulus, which is spread by the bite of an infected black fly.
