The diseases caused by intestinal parasites of the Eimeria genus tend to have a latent and often severe course in poultry fattening, especially in immunosuppressive individuals and young animals. Their treatment is complex and costly. It is also not very effective when compared with prevention.

These species belong among smallest unicellular parasites of mammals and birds. In external environment, their oocysts even rank second in the world, as to their resistance. They are not only resistant to adverse environmental influences, but they are also not enough sensitive to commonly used disinfectants.

They are transmitted most often by contaminated water, feedstuff and regularly also by environment. In the case of free ranges in the vicinity of fields, forests and watercourses, also by direct contact with infected wild animals or faeces of infected individuals. Exceptionally, they can be transmitted passively, but in subliminal doses. The infectious dose for these single-species endoparasites is usually 50,000 OPG (oocysts per gram of faeces). But the oocysts detected in contaminated farms reach over 200,000 OPG!/p>

Infectious diseases caused by these endoparasites occur mainly in environments with low level of hygiene or where sanitation is not performed regularly. When acute infection outbreaks, it is necessary to initiate treatment immediately and to add anticoccidials, but also to decontaminate the environment. In the near future, the use of anticoccidials will be limited because of AMR control. However, resistant oocysts cannot be destroyed in the environment in the presence of animals.

Besides to the destructive use of strong caustic at 60°C or flame burning, there are two basic procedures for effectively eliminating Eimeria oocysts in an environment with incomparably lower risks and higher efficiency. Each of them has certain benefits:

1. When there is a lower endoparasite load in the poultry hall, we recommend the combination of two preparations:(washing) and (disinfection)

• target organisms: Eimeria tenella, E. maxima, E. acervulina, bacteria, fungi and their spores, viruses.
• Efficiency from 10°C, hard water WHO, mild org. contamination, at 300ml of solution per m².
