lymphedema of an extremity (elephantiasis) can be the result of an infestation by which of the following parasites?
entamoeba histolytica
wuchereria bancrofti
diphyllobothrium latum
plasmodium vivax

Explanation:

Wuchereria bancrofti is a filarial nematode that infects the lymphatic system. When it infects the lymphatic vessels, it can cause obstruction of lymph flow. Over time, this obstruction leads to the accumulation of lymph fluid in the tissues, resulting in lymphedema. In severe and chronic cases, this lymphedema can progress to elephantiasis, characterized by gross swelling and thickening of the skin and underlying tissues in the extremities.
Entamoeba histolytica causes amoebic dysentery and liver abscesses. Diphyllobothrium latum is a tapeworm that causes vitamin B12 deficiency and anemia. Plasmodium vivax causes malaria.

Answer:

Wuchereria bancrofti
