Ixodes ricinus tick bacteriome alterations based on a climatically representative survey in Hungary

Area of Science:

• Ecology and Environmental Science
• Microbiology
• Vector-borne Disease Epidemiology

Background:

• Climate change is altering ecosystems, affecting disease vector populations and their associated microbiomes.
• Changes in tick microbiomes can influence the transmission dynamics of pathogens like Lyme borreliosis (LB) and tick-borne encephalitis (TBE).
• Ixodes ricinus is a primary vector for numerous pathogens in Central Europe.

Purpose of the Study:

• To assess how climatic factors influence the microbiome composition across different developmental stages of Ixodes ricinus.
• To understand the relationship between environmental changes and microbial shifts within ticks.
• To provide insights for developing novel strategies for tick-borne disease control.

Main Methods:

• Collection of Ixodes ricinus ticks across various developmental stages.
• Environmental data collection for climatically representative assessment.
• Microbiome analysis to determine microbial relative abundance and interactions.

Main Results:

• Identified significant variations in tick microbiomes correlated with climatic factors.
• Observed distinct microbial community structures across different tick life stages.
• Documented potential shifts in microbial interactions influenced by environmental conditions.

Conclusions:

• Tick microbiomes are sensitive to climatic variations, impacting pathogen transmission potential.
• Understanding these climate-microbiome interactions in Ixodes ricinus is crucial for predicting and managing vector-borne diseases.
• This research supports the development of climate-informed strategies for tick control and disease prevention.
