Meaning and Definition
The early larval stage of a parasitic filarial worm, found in the blood or tissue of infected hosts.
In medicine and parasitology, it refers specifically to the minute, pre-larval forms of filarial nematodes (e.g., Wuchereria bancrofti, Onchocerca volvulus) that circulate in blood or migrate in skin, and which are transmitted by insect vectors to continue the lifecycle.

FAQ
Frequently Asked Questions
No, it is not a disease itself. It is the larval form of the parasitic worm that causes diseases like elephantiasis and river blindness.
No, they are microscopic and can only be seen under a microscope, typically in a stained blood or skin smear.
They are transmitted from one host to another through the bite of an insect vector, such as a mosquito or blackfly, which ingests them while feeding.
Microfilariae are the early, larval, circulatory forms that are infectious to vectors. Adult filariae are the mature, reproductive worms that live in the lymphatic system or tissues of the definitive host.
The early larval stage of a parasitic filarial worm, found in the blood or tissue of infected hosts.
Microfilaria is usually technical/medical in register.
Microfilaria: in British English it is pronounced /ˌmaɪkrə(ʊ)fɪˈlɛːrɪə/, and in American English it is pronounced /ˌmaɪkroʊfɪˈlɛriə/. Tap the audio buttons above to hear it.
