CLIMATE-INDUCED MECHANISMS OF VARIABILITY IN THE DISTRIBUTION OF YERSINIA PSEUDOTUBERCULOSIS
Abstract
This paper explores the multifactorial relationship between global climate change and the epidemiological behavior of Yersinia pseudotuberculosis, the causative agent of pseudotuberculosis — a zoonotic infection transmitted primarily through contaminated food, water, or animal contact. The analysis focuses on how climatic factors such as increasing global temperatures, fluctuations in humidity, changes in precipitation, and the frequency of extreme weather events influence the ecological niches and survival mechanisms of the pathogen.
The study emphasizes that these environmental alterations reshape the natural reservoirs and transmission pathways of Y. pseudotuberculosis, ultimately affecting its spread among human populations. Special consideration is given to the climatic and ecological conditions of Uzbekistan, where shifts in temperature and sanitation practices may facilitate bacterial persistence and seasonal outbreaks. The paper highlights the importance of integrating climate-adaptive epidemiological surveillance and preventive strategies to mitigate climate-driven infection risks.
