In case of contact with the skin, the first symptoms may develop in 5-7 days.

It is important to note that, in addition to external problems, have deprive a bad effect on the health of animals. Thus, in young cattle and calves, it inhibits growth and development. In adult cows it often causes exhaustion and decreased productivity.

Forms of the disease

The main symptom of the disease is the occurrence of dense tubercles with the subsequent death of skin cells and hair loss. In calves, most often the disease affects the head, the area near the eyes, mouth, on the forehead, near the ears is vulnerable. In adult cows, it is found all over the body, especially on the neck, chest and back, as seen in the photo. Today, there are several forms of depriving:

On fallen crusts of skin and on hair follicles, they can live up to 1.5 years. When boiling, they die after 3 minutes, with a 100-degree heat treatment - after 20 minutes, the ultraviolet rays destroy spores within 30 minutes. Disinfectants, in particular, formaldehyde, carbolic acid, salicylic acid destroy the fungus within 15-30 minutes.
