A total of 13 clinical symptoms were identified, which have a slightly pronounced manifestation, and 6 - are expressed to a significant extent. The most frequent symptoms with a slight intensity of invasion are thirst (up to 30.77 %), decreased appetite and dullness of the coat (up to 23.08 %), abdominal wall tenderness (up to 20.51 %).
