What does Dracunculus medinensis infect?

The roundworm, Dracunculus medinensis, causes dracunculiasis or Guinea worm disease. Humans become infected by drinking unfiltered water containing small crustaceans that are infected with larvae of Dracunculus medinensis. The worm emerges from the skin in the middle of an ulcer as a white-looking filament.

How do you get Dracunculus medinensis?

Dracunculiasis, also known as Guinea-worm disease is a parasitic disease caused by the nematode Dracunculus medinensis. The infection is transmitted to humans by drinking water contaminated with the small crustacean copepods (Cyclops) which contain the larvae of D. medinensis.

How is Dracunculus diagnosed?

Diagnose based on observation of a white, filamentous adult worm at a cutaneous ulcer. Treat dracunculiasis by slowly removing the adult worm over days to weeks by rolling it on a stick or sometimes by surgically removing it.

What are the symptoms of Onchocerca volvulus?

Onchocerciasis, commonly known as “river blindness”, is caused by the parasitic worm Onchocerca volvulus. Symptoms include severe itching, disfiguring skin conditions, and visual impairment, including permanent blindness. More than 99% of infected people live in 31 African countries.

What is the vector for Dracunculus medinensis?

Vector Control The vector for GWD is the copepod. To control this vector, the GWEP puts a measured amount of the approved chemical temephos (ABATE®*) into the water sources that are suspected or known to be contaminated with Guinea worm-infected copepods.

What type of pathogen is Dracunculus medinensis?

Dracunculus medinensis, or Guinea worm, is a nematode that causes dracunculiasis, also known as guinea worm disease. The disease is caused by the female which, at up to 80 centimetres (31 inches) in length, is among the longest nematodes infecting humans.

How long does it take to remove a Guinea worm?

Because the worm can be as long as one meter in length, full extraction can take several days to weeks. Afterwards, topical antibiotics are applied to the wound to prevent secondary bacterial infections. The affected body part is then bandaged with fresh gauze to protect the site.

Is Dracunculus medinensis a filarial worm?

Dracunculus medinensis, the guinea worm, is not a true filarial worm, but is often grouped with the filariae.

What are the signs and symptoms of dracuncunculus medinensis infection?

The clinical manifestations are localized but incapacitating. The worm emerges as a whitish filament (duration of emergence: 1 to 3 weeks) in the center of a painful ulcer, accompanied by inflammation and frequently by secondary bacterial infection. A female Dracuncunculus medinensis in a human host.

What is dracunculiasis (Dracunculus medinensis)?

Dracunculiasis is infection with Dracunculus medinensis. Symptoms are a painful, inflamed skin lesion, which contains an adult worm, and debilitating arthritis. Diagnosis is by inspection.

How big do Dracunculus medinensis worms get?

Dracunculus medinensis. Dracunculus medinensis is similar to the filarids. The females measure up to 120 cm long and 2 mm wide and the males 2 cm. The worms mature in the connective tissue; gravid females then migrate to the subcutaneous tissue where they cause ulcers through which larvae are released when the lesion is immersed in water.

What is the life cycle of dracunuculus medinensis?

Life cycle of Dracunuculus medinensis : Lifecycle is completed in two hosts: Definitive host: Human. Intermediate host: Cyclops and other twelve species. Entrance into man and development into adult worms: Man acquires infections by drinking unfiltered water containing infected Cyclops.
