For millions of years, the nematode
Onchocerca volvulus has harbored bacteria that it needs to survive.
Several skin snips were taken from the shoulders, hips, and thighs bilaterally and submitted to the US National Institute of Health (NIH) which ruled out concomitant infection with
Onchocerca volvulus. Co-infections with both filarial worms could complicate treatment for loiasis in patients with excessive microfilarial levels (> 30,000 microfilaria /mL); contraindicate treatment with ivermectin.; and place patients at risk of significant encephalopathy from host response reactions to dying microfilariae in the cerebral circulation and cerebrospinal fluid with resulting meningoencephalitis, cerebral edema, cerebral infarcts, and coma.
A study was carried out in Imo River Basin, Imo State, Southeastern Nigeria, to assess the prevalence and intensity of microfilaria of
Onchocerca volvulus in the area [9].

Transmission of
Onchocerca volvulus has been interrupted in 11 of the 13 foci in the Americas, leaving only 4% of the previous at risk population still needing continued mass drug administration.

Onchocerca volvulus recombinant proteins similar to vespid venom antigen 5.
It is spread to humans by the bite of black flies infected with the parasitic worm
Onchocerca volvulus. Its larvae, deposited by the fly's bite, burrow into the skin, where they mature and eventually send out tiny offspring called microfilariae that can migrate through the skin to the eye.
River blindness is caused by a parasitic worm known as the
Onchocerca volvulus. Larvae is deposited by blackflies which breed in rivers - hence the name of the infection.
When they bite an infected victim, the female black fly takes in larvae of the nematode that causes the illness, the filarian worm (
Onchocerca volvulus).

RIVERFLY BLINDNESS (Onchocerciasis) is caused by small worms called
Onchocerca volvulus.
