The increasing prevalence and expanding distribution of tick-borne viruses globally have raised health concerns, but the full repertoire of the tick virome has not been assessed. We sequenced the meta-transcriptomes of 31 different tick species in the Ixodidae and Argasidae families from across mainland China, and identified 724 RNA viruses with distinctive virome compositions among genera. A total of 1,801 assembled and complete or nearly complete viral genomes revealed an extensive diversity of genome architectures of tick-associated viruses, highlighting ticks as a reservoir of RNA viruses.

Tick-borne bacteria and protozoa can cause a variety of human and animal diseases in China. It is of great importance to monitor the prevalence and dynamic variation of these pathogens in ticks in ever-changing natural and social environment. Ticks were collected from Heilongjiang and Jilin provinces of northeastern China during 2018-2019 followed by morphological identification.

Article Synopsis
  • * A systematic review and meta-analysis of studies published between 1976 and 2020 revealed an overall prevalence of 30.5% for C. sinensis metacercariae in fish, with the highest rates observed in China (35.1%) and the lowest in Vietnam (8.4%).
  • * Factors such as climate, water source, and publication date were significant in influencing prevalence rates, indicating a pressing public health issue related to this parasite in the region.

Among arthropod vectors, ticks transmit the most diverse human and animal pathogens, leading to an increasing number of new challenges worldwide. Here we sequenced and assembled high-quality genomes of six ixodid tick species and further resequenced 678 tick specimens to understand three key aspects of ticks: genetic diversity, population structure, and pathogen distribution. We explored the genetic basis common to ticks, including heme and hemoglobin digestion, iron metabolism, and reactive oxygen species, and unveiled for the first time that genetic structure and pathogen composition in different tick species are mainly shaped by ecological and geographic factors.

Both Clonorchis sinensis and Metorchis orientalis are the fish-borne zoonotic trematodes, and have a wide distribution of southeastern Asia, especially in China. Due to the similar morphology, life cycle, and parasitic positions are difficult to differentiate between both metacercariae. In the present study, the complete rDNA sequences of five C.
