Mite settlement. Argassic tongs

The mite of the village of the Agrasov family belongs to the class of arachnids, parasitomorphic mites, which are very common in the territories of the post-Soviet space. It is for this reason that every person must necessarily know what actions to take when biting so that the mite does not cause serious diseases. It is noteworthy that a tick can bite both people and pets who are in constant contact with family members and especially young children who are the most vulnerable, because they do not understand the seriousness of what is happening, they often do not tell their parents about the bite.

Description

Argas pincers are carriers of many diseases, the most dangerous and widespread of which are spirochetes and the Central Asian form of tick-borne spirochetosis. In addition, they can carry on themselves:

• Taiga encephalitis.
• Tularemia.
• Sypnotifoznuyu a fever.

It is noteworthy that the diseases that the adult can tolerate can be transmitted to the larvae by inheritance. Basically, this applies to infectious or parasitic diseases that penetrate directly into the ovum. It is for this reason that the population of mites is often a serious threat to a stable epidemiological situation. Creating a so-called reservoir of serious viruses, which can suddenly occur almost anywhere in the world.

Structure

In order to timely take the first medical help with a bite, everyone should know what a village tick looks like, the structure of which makes it possible to distinguish it from most blood sucking insects. The body of this tick is of longitudinal or oval shape, resembling an egg. Proboscis is located on the ventral side, with the dorsal shield completely absent. The cover of the trunk of the argasid tick is chitinous and small.

The sexual identity of an individual can not be determined without special knowledge and appropriate devices, because sexual dimorphism is very weakly expressed. In addition, this species received from nature a characteristic welt that runs along the edges of the body and creates a visual edge on it.

Food

The tick of the village can consume the blood of any vertebrate, regardless of age and individual characteristics. At the same time, the time required for complete filling of the stomach is from 3 minutes to an entire hour, it all depends on the temperature conditions in which the bite was carried out. During the stay on the body, the tick can consume blood that is 12 times greater than its own weight.

Be sure to consider that if you have a tick detected on your body, then you can become a direct carrier of serious diseases. The scientists managed to find out that it is the mites belonging to the family of argas that can infect you with tick-borne typhus, and the causative agent of the disease is transmitted in several ways, transovarial and transphase.

Reproduction

Bipolar reproduction allows for stable reproduction, which has a significant effect on the rate at which a village tick develops. The development cycle includes a phased transformation. First of all, a larva is formed from the egg, which by repeated incarnations in the nymphal stage is transformed into a full-fledged argas mite.

A female lays eggs immediately after she completes drinking blood. At the same time, he tries to choose the most secluded place for them. On average, their number does not exceed one hundred at a time, however, during its life, it can annually lay aside about a thousand eggs, each of which will subsequently grow a new tick, needing food.

Larvae

After leaving the food source, the mites begin to mate. Of the eggs that the settlement mite has postponed, completely formed larvae begin to leave within a month, which immediately begin to look for themselves the first sources of food. In the future, it is the first blood they use that will serve as the main impetus for further development into a full-fledged individual. At this stage of development, the mite size does not exceed 2 mm, and the color is dominated by a beige or light brown hue.

In the event that the temperature at the time when they find a source of food for themselves will remain favorable, the standard development cycle is about a year, under unfavorable conditions it can increase to two years. At the same time the mass of their body for several days increases by more than 20 times. The body of the mite is covered with small spines that undergo moulting as they grow.

In the future, a fully developed tick can not eat for up to 10 years, without experiencing much discomfort from forced starvation. In general, the time required to spend a tick in order to go through all the stages of development is up to a quarter of a century.

The main types and characteristics of mites

In order to be able to distinguish Argas tick from the others and apply the most appropriate treatment in a timely manner, it is not superfluous to know what the remaining representatives of ticks are, the most common among which have been:

• Argas ticks - prefer to live in enclosed spaces, whose role is played by a variety of cracks, burrows, caves, as well as living quarters.
• The gas mites are small eyeless mites, the size of which does not exceed 5 mm. Most often parasitize on birds and small mammals, through which a person transmits a variety of different viral pathogens.
• Tyroglyphy - most often found in the home. The main places that are suitable for reproduction are different food stocks, in particular, various cereals and flour. The main problem that arises in a person who consumes food infected with these mites is necrosis of the intestine. In addition, by entering into direct contact with the human skin, these mites leave on it in most cases a rash and irritation. Individuals can even live on the human body or pets, causing constant discomfort.

Life periods

The village tick, whose life cycle is in most cases short, ranging from several months to several years, is a real threat, because under favorable conditions, life expectancy increases to 20-25 years.

Completely forming into an adult individual, the village mite changes its rough skin, but there are no thorns on it completely. Limbs 8, with the genital opening located between the first and second pair of legs, on the lower part of the trunk. In females, this is a gap, while in males the opening is covered with a special shield.

Bite

The tick on the human or animal body is a temporary ectoparasite. At the site of a direct bite, a small dark red knot with a pronounced edging of a pale color is usually observed. If you do not take measures to remove the tick in time, the nodule then grows and transforms into a hemorrhagic papule with a characteristic hemorrhage, the diameter of which usually does not exceed 8 mm.

The tick of the village, making a bite, irritates the body tissues, which results in a strong itching at the site of the bite, which is the main stimulus for promptly seeking medical help in most patients.

This happens for the reason that often a mite bites a person in places where a person can not see it and, as a consequence, take timely measures to eliminate it.

Precautionary measures

Since the village mite is the causative agent of most serious diseases, it is important not only to take timely measures to treat the bite, but also to carry out prophylaxis, which is extremely necessary in the warm season. Going to nature, it is worthwhile to make sure that most of the areas of the body are covered with clothing, such protection measures will not be superfluous when examining caves, both for tourist and research purposes.

It must be remembered that even with timely measures, a person is not immune from the dangerous consequences of a bite, which in rare cases can lead even to serious diseases of the brain or spinal cord, affecting neurological or mental abnormalities.

In the event that you plan to spend a certain time in an earthen house, for example, going on vacation, treat the room before direct settlement with the help of acaricides, which not only will help quickly destroy existing ticks, but also prevent the emergence of new ones.

Treatment

Having found out a bite on the body, it is necessary immediately to start disinfection of the affected area, treating it with hydrogen peroxide or greens, in order to reduce the risk of allergic reaction. Remember that it is not recommended to comb the place of the bite, as in the future this can lead even to the appearance of ulcers and secondary foci of infection.

It will be best, after consulting with a doctor, to reduce its effect with an antihistamine drug. The duration of healing of the bite itself takes no more than 2-3 weeks. In any case, do not engage in self-medication, it is best to contact the doctor in a timely manner, who will be able to identify and timely eliminate possible consequences.
