Filarioidea
Filarioidea
Filarioidea (pronunciation: fi·lar·i·oi·de·a) is a superfamily within the class of Nematoda, commonly known as roundworms. The term is derived from the Latin word "filum", which means thread, referring to the thread-like appearance of the worms in this superfamily.
Etymology
The term "Filarioidea" is derived from the Latin word "filum", meaning thread. This is in reference to the thread-like appearance of the worms in this superfamily. The suffix "-oidea" is a common ending in taxonomy, used to denote a higher rank of family.
Description
Filarioidea are parasitic nematodes that are typically long and slender, resembling a thread. They are known to cause a group of diseases collectively referred to as Filariasis. The most well-known species within this superfamily include Wuchereria bancrofti, Brugia malayi, and Onchocerca volvulus, which are responsible for lymphatic filariasis and onchocercaisis, respectively.
Life Cycle
The life cycle of Filarioidea involves a definitive host, which is usually a mammal, and an intermediate host, which is typically a blood-sucking insect. The adult worms live in the lymphatic system of the definitive host, where they produce microfilariae. These microfilariae are taken up by the intermediate host during a blood meal. Inside the intermediate host, the microfilariae develop into infective larvae, which can be transmitted to a new definitive host during a subsequent blood meal.
