disease The cause of the development of scabies is infection with parasites. The causative agent of this disease is a pussy mite of the genus Pyemotes ventricosus, which lives in grain dust and straw.
Infection occurs when the grain dust hits the skin or when it comes in direct contact with straw. Therefore, in the risk group for infection with straw scalding are workers of agricultural enterprises, elevators, grain storage, flour mill complexes, etc.
The causative agent of cereal scabies is named pussy mite due to the characteristic form of the body of the fertilized females. Male mite has a body length of about 0.12 mm, the immature female is slightly larger, they have an elongated body length of about 0.22 mm. The fertilized female mite acquires a spherical shape and increases in sizes up to 2 mm in diameter. Therefore, the pathogen can be seen without the use of optical devices.
The optimum temperature for propagation of mites is 15-25 degrees, however, they can exist and multiply in a wider range of temperatures from 10 to 37 degrees of heat.
Females of pest mites are viable, one person can lead to 300-400 young ticks. On the light from one female every day there are about 30 young individuals. Sexual maturity of mites occurs 6-12 days after appearance, depending on external conditions.
Poison mite, unlike scabies, does not penetrate the upper layers of the skin and does not produce scabies. He only curses the skin and feeds with the blood of the victim as it bites an insect such as a mosquito.
Clears a parasite on grains of crops, in straw, grass, hay, cotton and flour. A tick may be present on the equipment or in the walls of the premises where the grain is stored or processed. The most frequent contamination of cereal scabies occurs in direct contact with infected products. A significantly lower role in contamination with straw caries is played by the dust factor. Particularly favorable conditions for the infection of this type of scabies are created in the process of performing work on infected products. When shredding the grain, pressing the hay, at picking and cutting straw, in the preparation of flour, etc.
Clinical picture of
Mites of ticks occur on areas of the body, unprotected clothing - hands( hands and forearms), shoulders, chest, back, legs. After 2-3 hours on the skin there are characteristic rashes, the appearance of which is accompanied by severe burning and itching as with cholinergic hives.
Elements of rash with cereal scabies are located in close proximity to each other against a background of reddened and slightly swollen skin. The size of the rash may vary, from buckwheat to hazelnut. In addition to papules on the skin, bubbles are often formed, filled with serous or purulent fluid.
For the first 4-5 days, the intensity of symptoms increases, with common rash in patients, often the temperature rises. Close lymph nodes may increase, pain in the joints may appear.
Symptoms of straw scabies are kept for 10-15 days, after which they pass without a trace. On the sites of the rupture location, secondary hyperpigmentation is often formed.
In young children( up to 5 years old), the external symptoms of cerebrospinal fluid can be less pronounced than in adults.
Sometimes, during straw scabies, it is accompanied by allergic cough and non-life. These symptoms develop as a secondary allergic reaction to ticks bites.
Diagnosis of cereal scabies is complicated by the fact that the tick was not detected in the study of the contents of the rash elements. Therefore, in the process of diagnosis, an important role is played by collecting anamnesis, and confirming the fact of contact with grain, straw or similar products that can be infected by the tick.
It is important to distinguish the manifestation of straw scabies from urticaria, monomorphic erythema, and phlebotomoderma.
Treatment of scabies is carried out in the same way as the treatment of scabies common. Often, the following drugs are prescribed:
- Lindane. This formulation for the treatment of scabies is available in the form of creams or lotions. The drug is applied to the affected skin and washed off after 6-24 hours. It is used once( less often requires double application).

- Esdepalletrin is a synthetic drug that is available as an aerosol. Used once. The drug is low-toxic and conveniently applied.
- Ivermectin is an oral scabies preparation. Contraindications
- Ointment of benzylbenzoate is a traditionally used remedy for scabies. The drug is applied to the body after an evening shower. In the morning, the drug is washed away.
- Sulfur Ointment. This drug has long been used successfully enough to treat scabies. For adults it is recommended to use 33% ointment, for children - 10-15%.
In the treatment of straw scabies, antihistamines - Zodak, Claritin, etc. - are also used. Both of these drugs are also very effective for the treatment of allergic dermatitis, atopic dermatitis and eczema.

Treatment by folk methods

In the treatment of scabies, the juniper will help. You can use the berries and branches of the plant. A decoction of 100 grams of plant material and a liter of water are prepared. A decoction is used to wipe affected skin scabies.
Prevention and prognosis
Prevention of infection with cereal scabies is to thoroughly protect the skin against mites. Individual remedies include the use of respirators, safety glasses, overalls, including mittens and armlets. All these means of protection must be provided by workers who, in the course of their work, are confronted with grain, straw and other materials stored in the course of their work, in which a grain tick can live.
It is necessary to carry out preventive treatment of premises in which the presence of a tick is assumed. The fires of these rooms are gray, other disinfection measures are carried out. Regular disinfection should be subjected to clothing workers.
The forecast for cereal scabies is good, however, immunity to the disease is not made. When re-infected, straw scabies will disintegrate again.
