Eimeria is a genus of apicomplexan parasites that includes various species capable of causing .. mice (M. musculus) Eimeria weybridgensis – sheep (O. aries) Eimeria wobati – southern hairy-nosed wombat (L. latifrons) Eimeria zuernii – cattle (B. taurus). Eimeria zuernii is a species of the parasite Eimeria that causes diarrheic disease known as eimeriosis in cattle (Bos taurus), and mainly affects younger animals. Coccidiosis is usually an acute invasion and destruction of intestinal mucosa by protozoa of the genera Eimeria or Isospora. Clinical signs include diarrhea.

Eimeria zuernii is a species of the parasite Eimeria that causes diarrheic disease known as eimeriosis in cattle Bos taurusand mainly affects eimrria animals. The disease is also commonly referred to as coccidiosis. The parasite can be found in cattle around the globe.

Eimeria zuernii

Eimeria zuernii is a very host specific parasite that only infects cattle. After the oocyst hatch in the gut of the animal it releases 8 zoites that undergo two asexual cycles schizogony.


The first cycle happens inside the lamina propria cells and produces many small schizonts. The second generation of schizonts target epithelial cells in the cecum and colon. The second generation of schizonts undergo a sexual cycle gametogony which is also the time when clinical signs of the disease can be observed.

The release zuermii new oocysts destroys mucosal cells which can lead to loss of serum and blood.

This can be zuernui as bloody diarrhea. The time from ingestion of the parasite to the first signs of disease prepatent period is days. The infection status of an animal is evaluated by examining the oocysts using different flotation methods [3]usually by counting the oocysts under a light microscope and identifying the species of the Eimeria based on morphology.

Environmental factors can influence how fast new oocysts become infective and management of the animals living conditions and feed and how easily the animals get eijeria.

In general, pathogenic Eimeria species, including E. Following the initial infection with an Eimeria species the animal usually is protected by immunity to that species, and is less likely to develop disease. The majority of the parasites life is in the environment and both survival of the parasite as well as developing into an infective oocysts depends on these factors.


Eimeria zuernii – Wikipedia

The time from when the parasite has left the animal in the faeces inside an oocyst and has developed in to a parasite that can infect new animals, is called the sporulation time. High humidity and temperature can speed up the sporulation time and facilitate new infections faster, which can lead to regular outbreaks of coccidiosis.
