Infectious Disease Compendium

Dracunculus medinesis

Microbiology

A helminth. AKA Guinea worm.

Epidemiologic Risks

Drinking water in tropical Africa, the worm eventually migrates to the skin and forms an ulcer with the worm wiggling at the base. It is found in African frogs. If so, it will soon cease as a human pathogen as frogs go the way of the passenger pigeon (PubMed).

Sudan, Ghana, Ethiopia and Mali are the only countries with the disease.

Syndromes

Skin ulcer.

Treatment

Thiabendazole 25 mg/kg bid x 2 days, or metronidazole 5 mg/kg bid for 1 week decreases inflammation to allow easy removal of the worm over a week or so by progressively rolling out the worm onto a stick. Then sold at the Minnesota State Fair.

Tearing out in pieces can lead to anaphylaxis.

Notes

The can be a yard long.

D. insignis in dogs and carnivores and there are other animals with their own parasites

Worm on a stick; isn't that at the food court?
