Microfilariae Research Paper

W. bancrofti have two hosts for their life cycles; the definitive host being humans and their intermediate hosts being mosquitoes. When the parasite is an adult, it resides in the human’s lymphoids in the lower body of the human. The larvae in the first stage of the cycle, the microfilariae, are present in the human’s blood. The microfilariae have a sheath around them. This sheath, along with the area in which the worms reside, facilitates diagnosis of which species of microfilariae is in a patient. The microfilariae can be found mostly from 10:00 p.m. to 4:00 a.m. the next day. They move throughout the circulation throughout the day. They are present in the deep veins diurnally, and they migrate to the peripheral circulation nocturnally.
