Indicators of Erythrocytopoiesis in Herpes Infection of the First and Second Types of Horses

Abstract

The article presents the results of studies of erythrocytopoiesis in horses with herpesvirus infection of the first type (rhinopneumonia) and respiratory manifestations of herpesvirus of the second type and their coexistence in animals. In the general pathology of horses, herpesvirus infections of horses occupy a leading place, and diseases of mixed etiology, which occur with atypical manifestations of clinical signs, are of particular concern.
 The work was performed in 2018 on the basis of the laboratory of the Department of Microbiology, Pharmacology and Epizootology of Polissya National University on breeding horses belonging to the Nahiryan branch of PJSC "Rise-Maximko" Ternopil region. Blood for the study was taken from the jugular vein against Jugulares in the morning before feeding Diagnostic studies to confirm herpesvirus infection were performed in the reaction of delayed hemagglutination, reaction and diffusion deposition - for herpes of the first type and in the reaction and diffusion precipitation to herpesvirus infection of the second type.
 Evaluation of erythrocyte indices allows you to get an idea of the characteristics of erythrocytes, which is very important in determining the type of anemia. Erythrocyte indices often respond quickly to the treatment of anemia and can be used to assess the effectiveness of therapy. The studies revealed a significant decrease in the number of leukocytes P ≤ 0.05 in animals of all experimental groups. Regarding hematocrit and erythrocyte counts, a significant decrease in P ≤ 0.05 was found in horses affected by EHV-1, and in the case of coexistence of two types of pathogens - a significant decrease in P ≤ 0.01. Erythrocyte index indices for herpesvirus infection of the first type in horses were characterized by a significant P ≤ 0.05 increase in the mean hemoglobin concentration in erythrocytes and a significant P ≤ 0.05 decrease in the mean erythrocyte volume. In herpesvirus infection of the second type, the fluctuations of the indices were not significant. In the combined course of the two types of viruses in horses, a significant increase in P ≤ 0.05 hemoglobin content in one erythrocyte and a significant P ≤ 0.05 increase in the average volume of erythrocytes.
