Fly Tumbu - (tumbu fly) - large non-bloodsucking fly of the species Cordylobia anthro-pophaga, widespread in the countries of Tropical Africa. Females of these flies can lay eggs in soil contaminated with urine or excrement, or on clothing soaked in sweat or urine.

Usually, the larvae of these flies parasitize in the body of rats, however, upon their direct contact with humans, they can penetrate the skin, causing the formation of boils (see also Mias). After applying the oil to the swelling formed on the skin, these larvae are easily removed.

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>



Description of the disease

Miasis refers to entomoses - diseases that are caused by various types of insects. The group of entomoses includes such common diseases as head lice (infestation by lice) and caterpillar dermatitis (skin irritation after contact with hairs on the body of caterpillars).

The mechanism of development of myiasis is as follows: a female fly lays eggs or live larvae on mucous membranes, skin, wounds and abrasions on the body of a person or animal. The larvae feed on the tissues of the victim, make passages in the muscles. At the same time, the victim experiences severe pain, the damaged areas become inflamed, swollen, and rot.

Flies that lay larvae under the skin:

  • Tumbu is a large insect that lives in Africa;
  • Wolfart - the fly is found in the Middle East, in the Asian part of Russia, China and North Africa;
  • Gadflies - scientists have about 150 species of gadflies.

Fly eggs laid under the skin during a bite are almost impossible to detect, so at first myiasis develops unnoticed: a person thinks that he has a common pimple on his body. Infection with larvae can occur not only when an insect bites: for example, a female pedestal fly lays eggs in the soil, on dirty clothes. If the larvae released from the eggs get on the human skin, they immediately penetrate into it.

Types of myiasis caused by flies

According to the method of infection, myiasis can be divided into two types: accidental and obligate. An accidental disease is considered if the infection occurred as a result of a person's non-observance of the rules of hygiene, and the larva of the parasite entered the body with food, while wearing dirty linen. Obligate cutaneous myiasis develops when the skin is directly affected by parasites.

According to the habitat of the larvae, myiasis is divided into two types:

  1. Superficial - the life of the larvae occurs in the upper layers of the skin, so the parasites can be easily removed from the tissues.
  2. Deep - the larvae penetrate deeply located tissues; to extract the parasites, one has to resort to surgical methods.

Symptoms and Treatment

Immediately after infection with myiasis, a person may not feel anything - usually during the laying of eggs, insects secrete a special substance with anesthetic properties into the wound so that the victim does not notice the bite. Then, at the site of the introduction of the egg, edema, swelling appears, the person begins to experience itching. As the parasite develops and advances, other symptoms join:

  • pain;
  • a feeling of movement under the skin;
  • the formation of fistulas in the skin;
  • discharge from the fistula of fluid or pus;
  • increased body temperature;
  • chills, muscle aches;
  • nausea, vomiting;
  • in some cases, loss of consciousness.

Diagnostics

If there is a suspicion that a person is infected with dipteran parasites, a dermatologist, infectious disease specialist, ENT doctor, ophthalmologist or surgeon (depending on the location of the causative agents of the disease) reveal the pathology when examining the affected area using a magnifying glass. Wounds or ulcers are often overgrown with larvae. They can be found visually in vomit, in biological fluids, in feces and other excrement. If a person is sick with pathologies of the cavity form, studies of various secretions, smears from the vagina are carried out.

Differential diagnosis is required to exclude helminthic invasions, salmonellosis, food poisoning, urethritis, viral rhinitis, conjunctivitis. To make an accurate diagnosis, a person must pass an enzyme immunoassay in combination with a hemotest. ELISA allows you to obtain comprehensive information about the causative agent of the pathology, including:

  • type and localization of the parasite in the patient's body;
  • the intensity of its colonies;
  • the period of residence of the larvae in the tissues;
  • the stage of their development;
  • clinical picture of the disease;
  • the presence of complications.

Treatment and prevention of myiasis

First of all, a person must be rid of parasites. In case of skin pathology, the places of accumulation of larvae are treated with sterile oil. Without air, they cannot breathe and come to the surface. Then the focus of inflammation is disinfected with Furacilin and a bandage is applied. Sick organs of the genitourinary system are washed with antiseptic solutions. In the treatment of the oral form, the antiparasitic drug Ivermectin is used.

When the skin is damaged, the abscesses are opened and also subjected to careful treatment with antiseptics.

Intestinal illness is treated with laxatives to cleanse the digestive tract. In ophthalmomyasis, larvae are removed under local anesthesia, followed by eye rinsing with sodium bicarbonate solution. With severe cavitary lesions, a person needs surgical removal of parasites.

With severe cavitary lesions, a person needs surgical removal of parasites.

In order to avoid the manifestation of myiasis, some norms should be observed:

  1. Apply various insect repellents;
  2. Conduct the strictest disinfection of various wounds in animals;
  3. In order to prevent deep damage, it is necessary to timely treat any damage to the skin;
  4. An important role is played by the destruction of pests and their breeding grounds;
  5. Comply with food storage standards;
  6. It is strictly forbidden to eat foods that have expired;
  7. Eat only washed vegetables and fruits;
  8. Drink exclusively purified water;
  9. Observe the norms of their own hygiene (washing hands, changing clothes regularly, etc.);
  10. Eliminate bad habits in children from an early age.

There are general recommendations during the treatment period. You should use decoctions from black currant leaves, drinking plenty of fennel tea, decoctions from a medicinal plant - celandine. It is recommended to add garlic, caraway seeds, onions and cinnamon as spices to various dishes.

For the cutaneous form of the disease, you should use special ointments made on the basis of birch tar or sulfur. With the intestinal form of the disease, it is possible to use enemas with bitter medicinal herbs.
