Parasitic subcutaneous in humans

Who are the subcutaneous parasites? How can you recognize them and get rid of them? Are there any preventive measures? You can now find answers to these questions.

So, how to recognize subcutaneous parasites in humans? Symptoms, photos will help to cope with this task. Note also the fact that many species live and spread only under specific climatic conditions, but there are also some that can be found in the city. As a rule, the latter are spread by insects. We will talk specifically about each species in the article.

Danger to people

Subcutaneous parasites in humans, the symptoms and photos of which will be considered further, cause a different degree of epidermal damage. The most common signs are:

  • irritation;
  • Itching;
  • Ulcers;
  • inflammation;
  • hair loss.

Now we suggest to consider what creatures can live on the skin and under its covers. All this is clearly shown in the table below.

Protozoa Organisms

Representatives of this class are Leishmania


This includes a whole list of organisms, among which rishty, gnathostomies and others


This group includes species of fleas


There are a lot of them

Many mistakenly suggest that these skin problems are caused by non-compliance with hygiene rules. By no means, the reasons for their emergence are other situations:

  • The use of raw foods (and also water);
  • The use of unprocessed and unwashed products (many have a habit of eating vegetables, fruits or berries straight from a bed or a tree);
  • Insect bites;
  • Close contact with the infected.

What are the dangerous subcutaneous parasites for humans? They are the causes of some diseases.


This is an inflammation of the pancreas. What is the cause of the disease? In most cases - the defeat of the intestines by parasites through penetration into the duct of the pancreas.


This is a non-infectious chronic skin disease that can occur as a result of many factors. The theory of parasite influence also exists.


These are non-contagious and diverse rashes on the skin of a person. With this disease, the victim experiences burning and itching.


This is a deficiency of the hormone insulin, which is produced by the pancreas. As a result of his lack, there is a steady overestimated blood glucose level. One of the causes of the disease is intestinal parasite damage.

It is worth noting also the fact that in people suffering from psoriasis, in 99% of cases is found and diabetes.


What is the danger in the presence of subcutaneous parasites in humans? Treatment is possible only after an accurate definition of the pathogen, since it directly depends on the type of parasite. Skin diseases caused by these organisms are dangerous because they can accumulate and as a result collect whole colonies. Inaction, they affect vital organs.

What skin diseases can be caused by parasites? First of all, it is scabies, pediculosis, demodectic and others. The earlier the disease is diagnosed, the easier it will be to get rid of the cause. Be sure to consult a doctor with this problem, and do not self-medicate.

I would also like to say that the disease is easier to prevent than cure. Prevention of parasitic skin diseases is also presented in the article.


Let's start with the disease, which is called leishmaniasis. It is caused by the simplest subcutaneous parasites. It is very important to note that the problem is often found in countries where the climate is warm.

There are several types of disease:

  • cutaneous;
  • Mucocutaneous skin;
  • visceral.

Leishmania for its entire life cycle is able to change two hosts. In this case, in each organism, it forms an inflammatory or flagellar form. Who or what is the source of distribution? These are infected animals and humans. The insects carry the disease, and they feed on contaminated blood. This happens by the transmissive method (that is, through a bite). A week after infection with the mosquito, he will become a carrier of the disease for life.

The disease manifests itself in this way:

  • Lethargy;
  • Decline in efficiency;
  • Sleep disorders;
  • fast fatiguability;
  • Poor appetite;
  • The appearance on the skin of painful ulcers (leishmaniom).

It should be extremely careful, leishmaniasis can easily be confused with a number of other diseases (typhus, sepsis, malaria and so on).


Subcutaneous parasites can cause a disease called gnathostomosis. The first and very important difference from the previous ailment is the way of infection. With leishmaniasis, human infection occurs as a result of an insect bite, but with gnathostomosis when the person is eating an intermediate host (the carrier of the disease). Intermediate hosts can be the following organisms:

  • a fish;
  • frog;
  • snake;
  • bird.

Cause nematode disease. It is important to note that the person in this case is an accidental host. Larvae in the human body can not develop. However, in many vertebrate carnivores, the normal life cycle of these parasites is observed, and they will be the final masters.

It manifests itself in this way:

  • Subcutaneous nodules;
  • dermatitis;
  • Pain;
  • Vomiting;
  • loss of appetite;
  • diarrhea;
  • fever;
  • weakness;
  • peritonitis;
  • Defeat of the central nervous system;
  • Lesions of the eyes;
  • Damage to the lungs.

Note that the last three items are very rare in practice. There are several types of disease: skin, eye, visceral, neurological.

The most dangerous form of gnatostomosis, which is associated with the migration of larvae into the nervous system. This can cause eosinophilic meningitis and encephalomyelitis. With this type of disease, larvae can migrate to the brain, which in most cases results in a fatal outcome.


Subcutaneous parasites are very dangerous. As mentioned above, they can form whole colonies. So schistosomiasis is caused by a whole group of parasites. It is very important that they lay eggs that have thorns. That is, they can freely enter any part of the human body:

  • bladder;
  • liver;
  • Spleen;
  • The uterus;
  • Circulatory system and so on.

Another danger is that clogs can form in the clusters. As a result, tumors, cysts and the like are formed. Schistosomes are tied to a tropical climate. From the human body to the external environment, they fall with feces and urine. After passing through some stages of maturation, the larvae look for a new master and make their way right through the skin to his body. Their task is to get to the right heart department. There the larva of the schistosome ripens and after a month of stay in the human body it is ready to lay eggs.

Symptoms in the gastrointestinal form of the disease:

  • Abdominal pain;
  • Intestinal disorder;
  • flatulence;
  • Bleeding;
  • weight loss.

Symptoms of the urogenital form:

  • Women have a malfunctioning menstrual cycle;
  • Miscarriages;
  • Sexual weakness in men;
  • Spotting in the urine and so on.

Symptoms common to all types of illness:

  • rash;
  • Itching;
  • fever;
  • headache;
  • diarrhea;
  • Blood or mucus in the feces;
  • depression;
  • weakness;
  • Fatigue and so on.


Subcutaneous parasites ( risto worms ) are capable of causing a disease called dracunculiasis. How does the person get infected? Everything is very simple, in dirty water can contain small crustaceans, which are already infected with parasites. When it is used, the crustaceans die, and the larvae are released and begin to actively develop.

This disease is common in areas where there is no access to clean drinking water. Worms live under human skin. After entering the body, the larvae tend to enter the stomach or intestine. After they are able to penetrate the abdominal and retroperitoneal cavity. There they develop for three months without showing themselves. After the passage of this period, reproduction occurs (pairing of different sexes). When fertilization takes place, the females migrate to the tissues. During this period, a blister appears on the surface of the skin (often on the foot). Within three days it bursts and an alive worm is released. This process is accompanied by a burning sensation, and a person is often forced to lower the affected area of the skin into the water, and infection occurs.

How to prevent infection? Everything is simple, you need to clean the drinking water with filters and the process of boiling.


Subcutaneous parasites in human filarias can cause disease of filariasis. This disease is tropical. You can get infected through the bite of an insect. Only after two years can the filariasis be detected in the form of mobile and painless nodes.


  • rash;
  • Elevated temperature;
  • Enlarged lymph nodes;
  • Subcutaneous accumulation of worms;
  • Lesions of the eyes;
  • Drowsiness and so on.

In this disease, several stages are distinguished:

  • Early (comes in three months after the bite of an insect, the duration of the period is six months);
  • Carriage (maturation of worms, the period may last for seven years);
  • Blockage (clogging of the luminal lumens).


Now we will consider one more subcutaneous parasite. Symptoms of dirofilariasis:

  • Subcutaneous compaction, which has the ability to move (primarily it appears at the site of the insect bite);
  • Sensation of creepy;
  • pain;
  • redness;
  • Itching.

The disease is caused by a filiform nematode. In animals, it is more common, but now people are more often infected with people. The way of infection is insect bites.


Subcutaneous parasites in humans, the symptoms and treatment of which we are considering in the article, can be presented in the form of insects. For example, in our case it is a sand flea.

It's quite easy to get infected. Do you like the sea and often go on vacation? Be careful with walks barefoot on the sand, there can hide a very small insect that can gnaw through the skin and stay with you for a long time, causing a lot of inconvenience.

The person thus experiences an itch and a burning sensation in a place of a sting. Soon the parasite will die and he will come out.

There is another dangerous parasite that is carried by insects - the human gadfly. The larva, which enters the human body, leaves on its own in a year.


Subcutaneous parasites in humans, photos provided in sections of the article, may be ticks. In humans, the most common are two types:

  • Itchy;
  • Demodex.

Infection occurs as a result of close contact with a sick person. Symptoms:

  • Itching;
  • A thin strip, which is visible under the skin (traces of the female when laying eggs).

Treatment and prevention


Preparations "Solyusurmin", "Neostibozan", "Glucantim", "Amphotericin B". Obligatory local therapy, treatment of affected areas, dressings.


Removal of the pathogen (this is not always possible). If localization is inaccessible place, then medicinal treatment is used: Albendazole, Ivermectin.


Treatment is reduced to the restoration of damaged areas and gradually introduced drugs (Biltricid, Prazikvantel, Astiban, Fuadin).


There are no drugs for treatment. It is necessary to wait for the release of the parasite.


Therapy consists of several stages (impact on larvae, destruction of adult individuals, surgical removal of parasites).


Surgical method, since education has a tendency to move, then a day before the operation, the drug "Ditrazin" is prescribed.


You can get rid of parasites with the drug "Ivermectin".


Ticks are also subcutaneous parasites. Treatment is carried out by a complex method (preparations of external and internal application).

For preventive maintenance, wash fruits and vegetables before use, filter and boil water, use insect repellent, in public places (including the beach), use personal slippers, do not wear someone else's clothes.
