Introduction of ticks. What is the difference between it and mites?

Acari belongs to Acari, tick superfamily, also known as ticks, grasshoppers, cattle ticks, grasshoppers and cattle turtles. Adult worms have shield plates on their backs and strong crusting ability, commonly known as Ixodes, belonging to Ixodes; Commonly known as soft ticks without shields, they belong to the family of soft ticks. About 800 species have been found in the world, including about 700 species of Ixodidae, about 150 species of soft ticks and about 1 species of nano ticks. There are about 100 species of Ixodidae recorded in China, and about 10 species of Ixodidae.

Ticks are temporary parasites on the surface of many vertebrates. They lie dormant in the grass of shallow mountains and like to hide behind tea leaves. It is the size of a grain of rice when it is not sucking blood, and it is as big as a fingernail when it is full of blood. It is the transmission medium and storage host of some human and animal diseases. The anaplasmosis caused by tick bites is an infectious disease, and people are generally susceptible to infection. People who are in close contact with critically ill patients and people who are in direct contact with body fluids such as blood of patients may also be infected.

The difference between Acari and Acari;

1. Physiologically, mites and ticks belong to Acari, but they are quite different. Mites are very small, generally about 0.5 mm in length, some as small as 0. 1 mm, and most species are less than 1 mm, and they are generally difficult to see with naked eyes, while adult ticks are 2 ~ 10 mm in length.

2. In the degree of harm, the common harm of mites is to induce allergies, which will cause allergic dermatitis, allergic rhinitis and other diseases; Ticks, like mosquitoes, are important vectors of many infectious diseases in the world. Diseases transmitted by ticks can lead to the death of patients in severe cases.

Extended data:

Mites are generally parasitic on the epidermis of some animals and are the vectors of some human and animal diseases. It is not very pathogenic in itself. If ticks carrying these germs bite people, patients may be infected with some viruses, which may lead to major diseases.

In 20 10, 557 cases of suspected azoospermia (tick poisoning) were found in Henan * *, and 8 cases died10; 182 cases were found in Shandong, and 13 cases died. There are cases of death caused by ticks in the whole country 12 provinces.

Tick control measures are as follows:

1, improve environmental sanitation and personal hygiene.

2. Don't sit and lie in grasslands, Woods and other environments for a long time to avoid being bitten by ticks. If you need to enter these areas, you need to do personal protection and expose your body as little as possible, such as wearing tight long-sleeved underwear.

3. Ticks are often attached to the scalp, waist, armpit, groin, ankle and other parts of the human body. If ticks are found attached to the body, they should be removed immediately with tweezers and other tools. Do not directly remove ticks by hand or crush them with your fingers. Control vector transmission and host animals (i.e. ticks, rats, pets, etc.). ) and properly manage the blood and secretions of patients with anaplasmosis.

4. Once there are suspected signs, you should take the initiative to seek medical treatment and inform the doctor about the relevant exposure history.
