This paper provides an overview of parasitic diseases that affect animals, including trematodes, which are highly prevalent and create significant economic damage due to helminths. It also discusses the epizootological indicators and techniques for detecting these diseases in cattle belonging to the population of the Fergana region, namely in the Beshariq district of the Fergana canal past gods.
Significance of the subject matter. The evolution of the etiological agents of trematodes disorders is highly intricate and proceeds by the process of boss replacement. Thus, the larval development, transfer to the primary (definitive) and intermediate hosts, distribution, degree of animal infection, and respite of these insects are regulated by specific abiotic, biotic, and anthropogenic elements of the region. Abiotic elements encompass the humidity, temperature, oxygen content, chemical composition of soil and water, and the relevant circumstances in intermediate hosts such as water and land molluscs, and biotopes. Biotic variables encompass the environmental attributes that are specific to the intermediate and primary hosts of each parasite. The anthropogenic element refers to the human influence on the exacerbation or abatement of diseases and the dissemination of their causes to different areas.
