Cordylobia anthropophaga

Species of fly

Cordylobia anthropophaga, the mango fly, tumbu fly, tumba fly, putzi fly, or skin maggot fly, is a species of blow-fly common in East and Central Africa. It is a parasite of large mammals (including humans) during its larval stage.[1]C. anthropophaga has been endemic in the subtropics of Africa for more than 135 years and is a common cause of myiasis in humans in the region.[2]

Its specific epithetanthropophaga derives from the Greek word anthropophagos, "human eater".

The mode of infection by the Cayor Worm. Doctors Rodhain and Bequaert conclude, from their observations in the Congo Free State, that Cordylobia anthropophaga lays its eggs on the ground. The larvae, known generally as Cayor Worms, crawl over the soil until they come in contact with a mammal, penetrate the skin and lie in the subcutaneous tissue, causing the formation of tumors. On reaching full growth, the larvae leave the host, fall to the ground, bury themselves and then pupate. This fly is said to be the most common cause of human or animal myiasis in tropical Africa, from Senegal to Natal. In the region of Lower Katanga where these investigations were made, dogs appeared to be the principal hosts, although Cordylobia larvae were found also in guinea-pigs, a monkey, and two humans. The larvae are always localized on those parts of the hosts which come in immediate contact with the soil."

Ann. Soc. Entom. de Belgique, Iv, pp. 192–197, 1911) summary translation in Entomological News. 1911 Vol. xxii:467.

History of discovery[edit]

The larvae of the tumbu fly, Cordylobia anthropophaga, were first described in Senegal in 1862, and Blanchard first described the adult and gave it its name in 1872. In 1903, Grünberg placed the tumbu fly in a new genus, Cordylobia.[3]


Female tumbu flies deposit around 300 eggs in sandy soil, often contaminated with feces. The hatched larvae can remain viable in the soil for 9–15 days, when they need to find a host to continue developing.[4] If a larva finds a host, it penetrates the skin and takes 8–12 days developing through three larval stages before it reaches the prepupal stage. It then leaves the host, drops to the ground, buries itself, and pupates. It then becomes an adult fly able to reproduce and begin the cycle all over again.[5]

Clinical presentation in humans[edit]

Successful penetrations in humans results in furuncular (boil-like) myiasis, typically on the backs of arms or about the waist, lower back, or buttocks.[6]

C. anthropophaga rarely causes severe problems, and mainly causes cutaneous myiasis. Geary et al. describe the presentation of cutaneous myiasis caused by the tumbu fly: "At the site of penetration, a red papule forms and gradually enlarges. At first the host may experience only intermittent, slight itching, but pain develops and increases in frequency and intensity as the lesions develop into a furuncle. The furuncle's aperture opens, permitting fluids containing blood and waste products of the maggot to drain."[5]


Female tumbu flies lay their eggs in soil contaminated with feces or urine or on damp clothing or bed linens. Damp clothing hanging to dry makes for a perfect spot. The larvae hatch in 2–3 days and attach to unbroken skin and penetrate the skin, producing swelling and infection.[7] If the larvae hatch in soil, any disturbance of the soil causes them to wriggle to the surface to penetrate the skin of the host.[5]

Reservoir and vector[edit]

A natural reservoir is defined as an organism that can harbor a pathogen indefinitely with no ill effects. Although C. anthropophaga larvae can cause ill effects for animal hosts, relative to myiasis in humans, animal hosts are reservoirs.

Many animals are hosts of C. anthropophaga. The dog is the most common domestic host and several species of wild rats are the preferred field hosts. Domestic fowl are dead-end hosts; the larvae cannot develop when they enter the tissue of a fowl.[3]

Humans are, in fact, accidental hosts; tumbu fly larvae do not usually infect humans and are not necessary for the transmission cycle of the fly.[2]

A vector is an organism that carries the parasites (the larvae) from one host to another. The tumbu fly itself is the vector in a loose sense, because the female deposits the eggs in soil or on damp cloth, where the larvae can hatch and attach to human or animal skin.[7]


Cutaneous myiasis caused by the tumbu fly should be suspected when a patient who has just spent time in Africa presents with ulcers or boil-like sores. Definitive diagnosis is only possible when the larvae are found. They should be removed and allowed to develop into adult flies for identification and examination purposes.


When C. anthropophaga causes cutaneous myiasis, the larvae more often than not can be removed without any incision. Covering the punctum (the breathing hole) with petroleum jelly or similar substances cuts off the air supply and forces the maggot to the surface, where it is easy to capture with forceps. If this does not work, local anesthetic can be administered and an incision made to widen the punctum and remove the maggot.[5] Another treatment discussed in the March 2014 Journal of the American Medical Association is to inject a combination of anaesthetic and epinephrine into the insect's chamber. Less drastically, because larvae of C. anthropophaga have smaller hooked bristles on the cuticle than those of Dermatobia hominis, it often is practical just to push on each side of the hole to squeeze the maggot out, especially after first enlarging the punctum. It is important not to burst the larva to prevent the risk of granulomatous or serious inflammatory reaction.[8]

Patients should be monitored for additional and subsequent lesions, as development does not occur in unison and some larvae may take longer to reach the prepupal stage. Antiseptics or antibiotics may be useful to prevent bacterial infection after removal of the larvae, but in practice are not often necessary; the secretions of the larva tend to discourage bacterial growth. As a rule, the wound may be expected to heal readily.[9]


The tumbu fly is endemic to the tropical regions of Africa, south of the Sahara. Myiasis caused by C. anthropophaga is the most common cause of myiasis in Africa, but can be seen worldwide because of air travel, as human movements carry infestation outside endemic areas.[7]

Public health and prevention strategies[edit]

The fly commonly infects humans by laying its eggs on wet clothes, left out to dry.[10] The eggs hatch in one to three days and the larvae (which can survive without a host for up to 15 days) then burrow into the skin when the clothes are worn.[1] A prevention method is to iron all clothes, including underwear, which kills the eggs/larvae.[11][12]

Bedbugs have officially invaded. The CBS News Early Show reports that across the country, infestations are becoming so common exterminators are having a hard time keeping up. In New York City, the crawly blood-suckers are being spotted in upscale lingerie shops and trendy boutiques - one thing about these blood suckers, they have taste.


Brown and about the size of an apple seed, Cimex lentacularius hides during the day and comes out at night, (shown piercing the skin of its host and drinking its fill. The bites don't spread disease but leave red, itchy welts. Bedbugs are so hard to exterminate that some people simply throw out their furniture, clothing, and bedding.


Botflies aren't easily confused with common houseflies - they're hairy and about twice as big. They lay their eggs on a mosquito, which then lands on a person. Once hatched, the larvae invade the skin of the unlucky host (as seen in this photo).


The babies proceed to eat their way to the muscle, leaving a sore around the breathing hole they make in the skin. Here's the truly disturbing part: Infected people report being able to feel and even hear the maggots moving about. Surgery is often necessary to remove the organisms.

River Blindness

If you're planning a safari, be on the lookout for black flies, which can cause an illness known as river blindness. This swollen hand got that way after being bitten by a black fly infected by the nasty Onchocerca volvulos. Swollen flesh is one symptom of river blindness - others include eye sores and, eventually, blindness. Worldwide, it is the #2 cause of blindness, with about 90 percent of cases occurring in Africa.

River Blindness

This microscopic amoeba has a long name - Acanthamoeba keratitis - and a long rap sheet to match. If you wear contacts and like to camp, be extra careful about how you clean and insert your lenses. Make sure your hands are clean when you touch your eye, because acanthamoeba can invade the cornea, causing an infection that can lead to blindness. Acanthamoeba is common in nature and can be found in water, soil, and air.


If you're planning a vacation to South America, the Middle East, southern Europe or any of the 88 countries where sand flies like to hang, don't forget the insect repellent. Small and silent, the female sand fly can transmit a parasite that causes leishmaniasis. The bite is so small you might not even know you've been bitten - at first.


There are two ways to get sick. Cutaneous leishmaniasis causes severe skin sores, while visceral leishmaniasis attacks the internal organs. You'll know you have the skin kind within a few weeks or months of being bitten. If you get the kind that attacks your insides, it can be months or even years.


This bloody mess is the doing of a common leech. And if a leech can do that kind of damage, imagine what Tyrannobdella rex - the name means "tyrant leech king" - can do with its enormous teeth. So far he's been spotted in the Upper Amazon in Peru - as if people who live in the rain forest don't have enough don't scary critters to worry about.


This little nasty has a foot fetish. The threadworm, a.k.a. Strongyloides, is oddly attracted to the soles of the feet. Maybe that's why mom always made us put on shoes in the backyard. The larvae enter the bloodstream and travel to the lungs, where they break through the tissue and move up to the throat.


They might give you a clue that they've made your body "home" by the pneumonia-like symptoms you get as larvae move through the lungs. Or you might just get itching and swelling, and sometimes a red line under the skin that marks when they've been on the move. Untreated infection can lead to organ failure and death.


It's summer and you're watching your diet - good for you. But watch out for lettuce. If you eat raw produce that's hiding a tiny snail or slug, you might get infected with a sneaky little beast known as the rat lungworm. Seems snails and slugs can get the worm from eating rat feces - and then pass it along to humans.


Is escargot your thing? Make sure it's fully cooked. Is your kid a fearless eater? Warn him to stay away from garden slugs - children have been infected by eating them on a dare.


Planning a stay-cation? Don't be lulled into a sense of false security. Make sure you cook your BBQ thoroughly so you don't end up feeding your loved ones a side of tapeworm. Tapeworms attach to the intestinal wall, where they feed on nutrients from digested food.


Tapeworms are looong.Typically, they grow to about nine to 15 feet, though some reach 50 feet. Often the host doesn't even know it's there until the worm gets really big. Expect the symptoms, if you have any, to be flu-like: headache, nausea, stomach cramps.


Maybe the chilly waters off Cape Cod are more your style. Still, don't be cavalier about the ticks. In addition to the well-known Lyme disease, tick-borne illnesses include babesiosis, an illness sometimes called the Malaria of the North. Fire Island, New York, as well as Nantucket and Martha's Vineyard in Massachusetts are favorite haunts. If you get bitten by this bug, symptoms can include fevers and shaking chills.


Lucky you, you have tickets to the tropics! But watch for mosquitoes. Some females can inject you with the malaria parasite, which takes up residence in the liver. Left untreated, the parasites multiply in red blood cells. At best you'll feel like you have a bad cold. Worst-case scenario? Coma and even death.
