Abstract

The research conducted on the pathogen Theileria annulata, which causes tropical theileriosis, has provided valuable insights into its behavior and virulence under various environmental conditions. The studies, which involved isolates from Azerbaijan, Tajikistan, the North Caucasus, and different regions of Uzbekistan, have shown that environmental factors such as temperature and humidity play a significant role in the pathogen's virulence. One key finding is that unfavorable environmental conditions can lead to changes in the virulent properties of Theileria annulata. For example, high temperatures and low humidity may weaken the pathogen, making it less virulent. Conversely, certain conditions could strengthen the pathogen, increasing its virulence and pathogenicity. Additionally, the passage of the pathogen through highly susceptible animals can also influence its virulence. Through these processes, the pathogen undergoes genetic and phenotypic changes that impact its ability to cause disease in animals. Understanding these factors is crucial for developing effective control and prevention strategies against tropical theileriosis. By studying the behavior and virulence of Theileria annulata under different conditions, researchers can identify potential risk factors and develop targeted interventions to mitigate the impact of the disease on livestock populations.
