A video of a woman having a bot fly larvae removed from her lip has gone viral on YouTube.
According to the Inquisitr, the woman finally decided to visit the doctor after a swelling in her lip just got worse and worse.
The site adds that the a bot fly had entered her lip and laid eggs, and the larvae from the eggs began growing in her mouth.
A doctor can be seen wiggling the parasite in an effort to slowly coax it out, which he does in around a minute while the girl lays there looking horrified.
The doctor then shows off the parasite to the camera, and it's rather stomach-churning.
According to wikipedia, the bot fly larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut.
The human bot fly, Dermatobia hominis, is the only species of bot fly known to parasitise humans routinely.
Bot flies deposit eggs on a host, or sometimes use an intermediate vector such as the common housefly, mosquitoes, and even a species of tick.
The smaller fly is firmly held by the bot fly female and rotated to a position where the botfly attaches some 30 eggs to the body under the wings.
Eggs are deposited on animal skin directly, or the larvae hatch and drop from the eggs attached to the intermediate vector: the body heat of the host animal induces hatching upon contact or immediate proximity. Some forms of botfly also occur in the digestive tract after ingestion by licking.
The human bot fly occasionally uses humans to host its larvae.
