Tick symbiont-pathogen interactions : A systematic review A systematic review on tick-borne diseases, tick endosymbionts and potential strategies for controlling tick-borne diseases

This review explores #TickBorneDisease #epidemiology and how tick microbiota, #endosymbionts, and immune responses shape development, #GutHomeostasis, and #PathogenTransmission, highlighting symbiont–pathogen interactions as promising targets for disease control.

Evolution and comparative genomics of tick-associated Francisella endosymbionts: insights into metabolic pathways and historical biogeographic patterns Ticks (Ixodida) are the second most important vectors of infectious diseases in vertebrates, after mosquitoes. They also maintain mutualistic relationships with bacteria, such as endosymbionts that pr...
