Seasonal dynamics of influence of netels and cows with spontaneous anaplasmosis in the Kirov region

We studied the seasonal dynamics of infection (the extensity and intensity of invasion) of netels and cows during spontaneous anaplasmosis in livestock farms in the Malmyzhsky district of the Kirov region. At the same time, the dynamics of changes in the amount of hemoglobin in the blood of netels and cows at a different level of parasitemia was studied. Anaplasmosis of netels and cows in the Malmyzhsky district of the Kirov region proceeds in the form of carriage and is characterized by two seasonal outbreaks of extensiveness and intensity of invasion. The first outbreak is recorded in the winter stall period and is characterized by the highest degree of infection of netels (EI 83,3±11,5 %) and cows (EI 90±10,0 %), the second - before pasture to the pasture - with the highest level of parasitemia in the blood of netels (II 3,6±0,3 anaplasmas at 100 p.p. microscope) and cows (II 4,0±0,6 anaplasmas at 100 p.p. microscope). Cows are 8 % higher and 11,1 % stronger than anaplasmosis infected than netels. The amount of hemoglobin during the first and second outbreaks in the blood of netels and cows was near the lower boundary of the physiological norm. The hemoglobin in the blood of netels was 0,4 and 1,6 % higher than in cows.
