Video: Bancroft's Thread (filaria): Life Cycle, How To Get Rid Of A Person
Bancroft's filament is a parasitic worm of the nematode class that provokes the development of helminthiasis called Elephantiasis (wuchereriasis). Filamentous worms are also called Bancroft's string. Most often, these helminths are found in Asia and the southern regions. In other places, the appearance of the parasite is possible if it is brought in.

Filaria Bancroft enters the human body through the carrier of microfilariae. They are larvae of worms that are practically invisible to the human eye. The life cycle of filariae provides an intermediate and final host. The role of the latter is performed by any vertebrate animal, including humans. Initially, the larvae of parasites develop in the body of an intermediate host, which is the gnat (a collection of dipterans that feed on blood). In particular, Diptera insects transmit filariasis.
Once in the human body, mature filaments parasitize in connective tissues, lymph nodes, blood vessels and on the skin. Along with this, the filarial larvae perfectly circulate in the human blood. Dirofilaria immitis often accidentally enters the human body. An insect bite becomes a source of infection, after which microfilariae penetrate the human stomach, from where they move to the muscles, mature and pass into the invasive stage. The larvae are on the proboscis of an insect, which is why a person becomes infected after a bite.
Danger to humans
Symptoms of the disease caused by the filaria family are quite severe. As a rule, untimely therapy of parasitic infection causes the development of severe consequences that end in disability, because both internal systems and organs are infected.
The filamentous worm, localized under the skin, provokes the appearance of symptoms such as:
- dense papules;
- dryness, itching, and flaking;
- wounds and ulceration.
The filament is able to move to the lymph nodes and tubular formations, remaining parasitized there. The genitals, eyeballs are also susceptible to damage. If the parasite concentrates in the organs of vision, then conjunctivitis, exaggerated photosensitivity, inflammation of the cornea of the eye can develop.
Types of caused diseases
Once in the human body, the thread is capable of provoking the formation of the following pathologies:
- elephantiasis or wuchereriasis, brugiosis is filariasis, which occurs in a person's body in a chronic form. The symptoms of the disease include an increase in body temperature above 37 ° C, infectious inflammation of the lymphatic vessels of the extremities, funiculitis, inflammation of the male genital organs, abscesses, as a result of lymphostasis of the extremities, mammary glands;
- river blindness (onchocerciasis) is a chronic form of filariasis, accompanied by damage to the organs of vision, skin and hypodermis. In addition to lymphostasis of the legs, other dangerous consequences may occur;
- loiasis - filariasis characterized by a chronic course. As a rule, lymphedema occurs, the conjunctiva of the eye, organs of the reproductive system and serous membranes are affected by helminths;
- dirofilariasis is a zoonotic filariasis, during which several types of roundworms can simultaneously parasitize in the subcutaneous tissue. Tumors migrating throughout the body immediately become noticeable.
Filariasis and its distinctive features
Invasive disease is called elephantiasis. Helminth is a class of nematodes that can be 10 centimeters long. In the human body, the female develops offspring. By the way, parasitic females are much larger than males in size. The place of localization of the larvae is the bloodstream or thoracic duct.
Bancroft's thread is the most dangerous representative of roundworms. The parasitic worm is able to disrupt the circulation of lymph in the lower extremities, which is a rather serious deviation.
The life activity of a filamentous worm in a human body can last more than 10 years. During the period of parasitic existence, nematodes poison the human body with their toxic waste products.
The infected person experiences a painful condition caused by severe disorders. If you consult a doctor on time, and not conduct self-treatment, you can avoid dangerous pathologies.
Having penetrated the human body, parasitic worms rapidly reproduce and lead to a chronic parasitic process
Filariasis has several stages:
- Incubation - this stage is absolutely asymptomatic. A person may develop a minor painful condition that, as a rule, people do not take seriously.
- Toxic-allergic (early) - manifested by skin rashes. Often, papules of a dense consistency and small size are formed. Opening the nodules will cause ulcers, which cannot be removed without antiparasitic therapy.
- Clinical - there are signs characteristic of wuchereriosis. The severity of symptoms is determined by the number of nematodes and the degree of damage to the body.
- Obstructive - the lymphatic system is damaged, an inflammatory process of a purulent nature develops, and internal organs are affected.
The main symptomatology provoked by the filamentous worm is the accumulation of fluid in the scrotum, poisoning of the body with toxic substances, and increased body temperature. Purulent inflammation of the places where parasites have accumulated is possible. In females, the emission of urine may be delayed, and pain in the pubic region is formed. In men, the testicles may be affected.
- bronchial asthma;
- infection of the organs of vision;
- the formation of warts, eczema and papillomas;
- violation of skin pigmentation;
Diagnostics and therapy
Before starting the fight against the filamentous tissue, which is localized in the body, a specialist consultation is required. The patient will be assigned laboratory tests, according to the results of which the presence of parasites is confirmed or denied, and, if necessary, the correct therapy is prescribed.
The specialist prescribes treatment on an individual basis, taking into account the characteristics of the infected person.
Only a doctor can answer the question: how to deal with filamentous tissue. As a rule, therapy is carried out in stages. First of all, it is necessary to get rid of microfilariae, eliminate their waste products and death. Further, adult parasites are eradicated.
Effective anthelmintic drugs include medicines based on the drug Albendazole, Erythromycin, Ditrazine citrate, Ivermectin.
Anti-inflammatory and antihistamines can treat inflammation and allergies that cause toxins and death of nematodes.
Along with this, the drug Doxycycline is prescribed, which effectively fights against viruses and bacteria.
