ZOVER 2.0: a virome-based platform for zoonotic and vector-borne viruses

Year: 2025

Type: article

Abstract: Emerging zoonotic and vector-borne viruses pose a continuous threat to global public health, highlighting the need for effective virome surveillance that targets key wildlife reservoirs and vectors. Addressing this challenge requires a systematic understanding of both viral and host diversity, especially across broad spatiotemporal scales. Building on the previous genome-centric release, the upgraded ZOVER 2.0 (https://www.mgc.ac.cn/ZOVER/) expands its scope by incorporating 5883 curated metagenomic next-generation sequencing libraries from 72 independent projects, spanning 12 years and covering 362 distinct wildlife species of bats, rodents, mosquitoes, and ticks. To ensure consistent and sensitive virome profiling across heterogeneous datasets, ZOVER 2.0 employs a standardized analysis pipeline based on reads for taxonomic annotation and viral abundance estimation. After normalization, sequencing reads were collectively assigned to 110 recognized viral families, substantially expanding the known virome diversity within these four wildlife groups. Furthermore, a series of interactive modules enables users to visualize virome composition and perform comparative analyses across different host taxa, geographic regions, and temporal scales. By integrating current genomic and metagenomic knowledge, ZOVER 2.0 provides a robust platform for virus discovery, ecological interpretation, and surveillance of potential interspecies transmission, thereby contributing to One Health-oriented monitoring of emerging infectious diseases.
