Research progress on emerging and important Tick-Borne pathogens.

Ticks are important vector arthropods, which can carry and transmit a variety of pathogenic microorganisms, and pose a serious threat to global public health. This study reviews the research progress of the main and emerging tick-borne pathogens, such as Lyme disease related Borrelia, Rickettsia, Babesia, Thrombocytopenia Syndrome Virus (SFTSV), Tick-borne Encephalitis Virus (TBEV), Alongshan virus (ALSV), etc., focuses on their genomic diversity, pathogenicity, transmission and immune escape, co- infection. In addition, the application of new detection technology [Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR), metagenomic next-generation sequencing (mNGS), microfluidics] in Tick-Borne pathogens is summarized.It highlights current research limitations, including delayed vaccine development and inadequate surveillance systems. Finally, future research directions are prospected, providing theoretical references for the prevention and control of tick-borne diseases.
