Research overview: metagenomic virus discovery in wild felids

High-throughput sequencing has opened a new era of virus discovery, allowing researchers to catalog the viromes of wild felids without prior knowledge of which pathogens to seek. This overview surveys how metagenomic and viral-enrichment sequencing of blood, tissue and feces reveals known and novel viruses in lions, pumas and other cats, expanding the catalogue beyond the classic FIV, FeLV and distemper. It examines the promise of detecting emerging threats early, the challenge of distinguishing harmless commensal viruses from pathogens, and the bioinformatic and sampling hurdles involved. The synthesis connects unbiased sequencing to proactive disease surveillance. It aims to give readers a sense of how modern genomics is broadening our view of the hidden viral diversity carried by wild cats and its implications for conservation and spillover risk.
