Oral myiasis

Oral myiasis, a parasitic disease that develops as a result of the introduction of dipteran insect larvae into the oral cavity, is a rare pathology and almost never occurs in the Northern Hemisphere. Tropical countries such as Mexico, Africa, Guinea and South America are considered endemic regions.

Tropical countries: Mexico, Africa, Guinea and South America are considered endemic regions for the development of the parasitic disease of the oral myiasis.

Sources of infection

There are several types of myiasis, which differ from which part of the body the parasites are located in. Oral is the rarest. Going to hot countries, you need to know the pathogens that can cause the development of the disease.

First of all, these are flies: meat, Wolfart and Tumba. Insect females lay more than 300 eggs on the body or mucous membranes of animals and humans. According to statistics, the Cochliomya Hominivorax (meat) fly lives for about 20 days. During this period, it is capable of flying more than 2000 km, causing several types of myiasis, incl. and oral.

One of the most common sources of infestation is flies. Insect females lay eggs on the body or mucous membranes of animals and humans.

Some species of gadflies pose a great danger to humans, which can lead to infection by laying eggs on open wounds. The most dangerous are sheep and Russians. Both belong to the cavity type, i.e. have the ability to give birth to live larvae.

Sand fleas should also be careful. Penetrating under the layer of the epidermis or mucous membrane, they parasitize in the body of an animal or human, swelling to large sizes and causing various types of myiasis. Oral is no exception if the flea manages to get into the human oral cavity.

Signs and symptoms of the disease

Oral myiasis should be suspected if the person complains of persistent mouth discomfort, burning and itching in the gums and palate. Unpleasant sensations are explained by the movement of insect larvae.

Oral myiasis should be suspected if the person complains of persistent mouth discomfort, burning and itching in the gums and palate.

Common symptoms include the following:

  • Swelling and bleeding of the gums, pain when chewing hard food.
  • Oral edema often spreads to the sinuses. Then patients complain of nasal congestion.
  • With the extensive spread of infection, a deterioration in the general condition of a person is noted: the body temperature rises, weakness develops, a feeling of fatigue and aches in the joints and muscles appear.
  • Facial lesions are not uncommon. In such cases, swelling occurs on the lip, the skin turns red. It is difficult for a person to open his mouth to talk or eat.
  • Rarely, an oral form of pathology can cause a cough.

How a mouth infection develops

Insect larvae, which cause myiasis in the mouth, penetrate into the mucous membrane. Localization sites of parasites - gum pockets, palate, cheeks. More than 600 larvae can be in the patient's mouth at the same time.

Infection is more often observed in elderly people suffering from purulent pathologies of the oral cavity, in alcoholics or drug addicts, seriously ill patients who are not able to take care of themselves.

Feeding on human blood and tissues, the larvae increase in size and rupture the mucous membrane, becoming dangerous to the patient's life. Without timely treatment, oral myiasis can be fatal.

Oral myiasis treatment

In most cases, oral pathology is treated surgically. Places of accumulation of parasites are opened, the larvae are removed. Then the patient's oral cavity is checked for the presence of affected gingival pockets, fistulas and abscesses.

The oral cavity is treated with antibacterial and antiparasitic drugs (Ivermectin), which can cause paralysis of the larvae and their subsequent death. On open wounds, napkins soaked in antiseptic solutions and chloroform are applied.

Despite the fact that the oral type of pathology is rare, in order to prevent it, it is recommended to protect food from flies, eat only well-washed vegetables and fruits, especially tropical fruits, and not use stale meat and fish for cooking.
