A rare maggot disease in a 10-year-old girl in Brazil What is maggot disease

A 10-year-old girl in Brazil recently complained to her mother that "something was squirming in her mouth," and the dentist removed 15 live maggots from her swollen gums. Girl Ana suffers from oral fly maggot disease, a rare tropical disease caused by flies laying eggs in the population. A clinic spokesperson said that because the situation is very rare, it took a video of removing maggots to explain to Ana's family and remind the public to pay attention to hygiene.

What is maggot disease

A general term for diseases caused by the infestation of larvae of parasitic flies of the insecta diptera infested livestock. The main hazards are stomach fly maggot disease, skin fly maggot disease and nose fly maggot disease. Pastoral occurrences are widespread.

The adult flies of the parasitic fly are divided into three parts: head, chest and abdomen. In addition to the 3 pairs of limbs, there are 1 pair of forewings on the thorax, and the hindwings degenerate into balancers. The appendages at the end of the abdomen become external genitalia. Larvae, commonly known as maggots, have no heads, no wings, and no limbs. The whole insect body generally has 12 to 13 segments, but it is still divided into three parts: the head, chest and abdomen, the first section is the prosthetic head, the last 3 sections are the thoracic segments, and the last 8 to 9 segments are the abdominal segments. There are often many small spines on the dorsal and ventral surfaces of each body, and their size, number and arrangement are of distinguishing significance. Totally perverted. In addition to the fetal wild flies, they generally go through four stages: eggs, larvae, pupae and adult. Male flies die after mating; Female flies die after laying eggs or larvae and generally live no more than 1 month. Neither feeds nor bites livestock during spawning. The whole development cycle is about 1 year.

Maggot disease refers to a disease caused by the parasitization of larvae ---- maggots in humans or animals.

Maggots that can live parasitically are divided into obligate parasitism and facultative parasitism.

such as horse stomach flies (can cause maggot disease); sheep rhinophilia (causes disease of sheep rhinophilus); Larvae such as the cow skin fly and the cow striped fly (which causes psoriasis) and the spiral trypanosofly (which parasitizes within the wounds of animals and humans) are obligate parasites. Its larvae cannot survive or continue to grow and develop without their hosts.

The vast majority of fly maggots live freely, but some species of maggots may still enter the animal body and human parasitism once they have the opportunity, which is called facultative parasitism.

In addition to parasitic maggots that parasitize large animals, there are also maggot diseases caused by parasitic flies that parasitize insects, such as silkworm maggot disease. Adults lay eggs on the surface of the silkworm body, and after hatching, maggots pass through the body wall of the silkworm into the body cavity, feed on the fat of the silkworm, and secrete endohormones to control the behavior and growth of the silkworm. After the host has formed a cocoon, the main wall of the host is drilled out, the host dies, and the fly maggots pupate and feather in the cocoon. Silkworm maggot disease is a disease that seriously endangers silk farming. Outbreaks of epidemics can cause serious losses to sericulture farmers.

What are the symptoms of maggot disease

The main symptom of maggot disease is the mechanical stimulation of the host or patient by the maggots. The hairs, hooks, spines, migrations, etc. on the surface of the body of the fly maggot stimulate the body wall of the host. The patient will feel a tingling, pain, itching, foreign body sensation, migration sensation and so on in a certain part of the body. For example, patients with rhinopathy will sneeze and feel foreign bodies in the nose. Patients with genitourinary tract fly maggot disease will feel tingling sensation, shifting sensation, urinary frequency, urgency, pain of urination, etc. in the lower abdomen, urethra, vagina, etc. Patients with maggot disease will feel subcutaneous cone pain, there is a sense of migration under the skin, and the tunnel left by the maggots can even be seen under the skin. In addition, fly maggots have bacteria on their surface, which may cause infection. Maggots that cause maggot disease may enter the cranial cavity through the sinuses, causing serious consequences and even death. Maggots that cause eye maggot disease may enter the inside of the eyeball, destroying intraocular tissue and causing blindness. Some maggots feed on host body tissues, such as the maggots of the spiral fly. The consequences are severe, even death.
