Abstract:

A number of domestic and wild animals have been infected with eimeria in Kazakhstan. As a result, horses (Equus caballus Linnaeus, 1758) have one species of eimeria new to science (Protozoa, Apicomplexa), kulans (Equus hemionus Pallas, 1775) - 2, beavers (Castor fiber Linnaeus, 1758) – 3, saigas (Saiga tatarica Linnaeus, 1766) – 1, argali saryarka (Ovis ammon collium Linnaeus, 1758) – 4, steppe wild sheep (Ovis orientalis Gmelin, 1774) – 7, Bukhara deer (Cervus elaphus Bactrianus lydekker, 1900) – 3 species. Oocysts secreted by feces from the host’s body cannot infect sensitive animals. In the external environment, they must undergo a certain development process, during which they acquire the ability to infect. In the presence of certain conditions in the external environment (heat, moisture and oxygen), the cytoplasm of the oocyte separates from the shell, contracts, acquires a spherical shape and begins to divide into four sporoblasts. A dense shell forms around each sporoblast, resulting in the formation of four sporocysts. Two sporozoites are formed in each sporocyst, and sporocyst-spores. This ends the exogenous period of the development of emeria-sporogonia. After that, the oocysts become invasive and infect sensitive animals when they become infected. Morphological signs of eimeria are described. The timing of sporulation is indicated. The number of oocytes, sporocysts and sporozoites is given.

Key words: eimeria, sporocysta, sporozoite, horse, kulan, river beaver, saiga, saryarka argali, wild steppe sheep, bukhar deer.

Introduction:

Eimeria is one of the richest quantitative and qualitative groups of protozoa. The high ability to adapt to different ecosystems has allowed Eimeria to spread throughout the world and to master all kinds of animals. The vast majority of individual trees of all species that feed on Eimeria are to some extent infected with this pathogenic single-celled.

Eimeria is characterized not only by its wide geographical and ownership distribution, but also by its location within a single host, affecting different organs and tissues. Eimeria often develops in the intestinal wall, lymph nodes, kidneys, liver, bladder, endothelium and blood cells. Several species of amygdala are usually found in the body of one host, sometimes more than ten. By affecting various organs and tissues, these single-celled organisms cause disease, often inhibiting the growth and development of animals and often leading to death.

It is necessary to use rational methods and tools to combat animal hemorrhoids. But its effectiveness is possible only on the basis of sufficiently accurate data on the fauna, life cycles, bodies, order and distribution of emery.

In this article, we will introduce new types of emery.
