Causes of

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.

Scabies of Grain Cause, Symptoms, Treatment, Photo 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.
