Cutaneous larva migrans (abbreviated CLM) is a skin disease in humans, caused by the larvae of various nematode parasites of the hookworm family (Ancylostomatidae).The parasites live in the intestines of dogs, cats, and wild animals; they should not be confused with other members of the hookworm family for which humans are definitive hosts, namely Ancylostoma duodenale and Necator americanus.
Instead, the larvae migrate just below the skin producing snake-like markings. This is referred to as a creeping eruption or cutaneous larva migrans. [ 3 ] However, Ancylostoma ceylanicum , a canid and felid hookworm, is able to establish patent intestinal infection in humans and is thus a zoonotic cause of ancylostomiasis.
The larvae can move through the body without triggering a response from the host's immune system, so some people who are infected with the parasite experience no symptoms; the Global Burden of Disease Study estimated that in 2017 there were at least 20.9 million people infected worldwide, of which 14.6 million had skin disease symptoms and 1.15 ...
Patches of edema appear after initial symptoms clear and are usually found on the abdomen. [3] These lesions vary in size and can be accompanied by pruritus , rash , and stabbing pain. Swellings may last 1 to 4 weeks in a given area and reappear in a different location. [ 3 ]
Adult worms migrating across the eye are another potential diagnostic, but the short timeframe for the worm's passage through the conjunctiva makes this observation less common. [citation needed] In the past, healthcare providers used a provocative injection of Dirofilaria immitis as a skin-test antigen for filariasis diagnosis. If the patient ...
Dracunculiasis, also called Guinea-worm disease, is a parasitic infection by the Guinea worm, Dracunculus medinensis. A person becomes infected by drinking water contaminated with Guinea-worm larvae that reside inside copepods (a type of small crustacean).
