The environment, the tick, and the pathogen - It is an ensemble.

Area of Science:

• Environmental Science
• Microbiology
• Epidemiology

Background:

• Ixodes scapularis is a primary vector for Borrelia burgdorferi, the causative agent of Lyme disease in the USA.
• The geographic range of I. scapularis is expanding, posing a growing public health concern.
• Tick-borne disease prevalence is shaped by complex microbiological, ecological, and environmental interactions.

Purpose of the Study:

• To review critical environmental factors influencing tick biology and pathogen interactions.
• To highlight the impact of abiotic and biotic factors on Borrelia burgdorferi infection in ticks.
• To emphasize the need for a molecular understanding of these interactions for disease control.

Main Methods:

• Literature review focusing on environmental factors affecting tick-pathogen dynamics.
• Analysis of molecular studies on tick-host and tick-pathogen interactions.
• Examination of abiotic (temperature, humidity) and biotic (microbiota) influences.

Main Results:

• Environmental factors significantly impact tick biology and infection prevalence.
• Abiotic factors like temperature and humidity play a crucial role.
• Biotic factors, including environmental microbiota, also affect tick infection rates.

Conclusions:

• Understanding the interplay of environmental factors with tick-pathogen interactions is essential.
• Molecular insights into these interactions can lead to novel control strategies.
• Developing new approaches to control ticks and Borrelia burgdorferi transmission is critical.
