Detection of novel orthoparamyxoviruses, orthonairoviruses and an orthohepevirus in European white-toothed shrews

Original language description

While the viromes and immune systems of bats and rodents have been extensively studied, comprehensive data are lacking for insectivores (order Eulipotyphla) despite their wide geographic distribution. Anthropogenic land use and outdoor recreational activities, as well as changes in the range of shrews, may lead to an expansion of the human-shrew interface with the risk of spillover infections, as reported for Borna disease virus 1. We investigated the virome of 45 individuals of 4 white-toothed shrew species present in Europe, using metagenomic RNA sequencing of tissue and intestine pools. Moderate to high abundances of sequences related to the families Paramyxoviridae, Nairoviridae, Hepeviridae and Bornaviridae were detected. Whole genomes were determined for novel orthoparamyxoviruses (n=3), orthonairoviruses (n=2) and an orthohepevirus. The novel paramyxovirus, tentatively named Hasua virus, was phylogenetically related to the zoonotic Langya virus and Mojiāng virus. The novel orthonairoviruses, along with the potentially zoonotic Erve virus, fall within the shrew-borne Thiafora virus genogroup. The highest viral RNA loads of orthoparamyxoviruses were detected in the kidneys, in well-perfused organs for orthonairoviruses and in the liver and intestine for orthohepevirus, indicating potential transmission routes. Notably, several shrews were found to be coinfected with viruses from different families. Our study highlights the virus diversity present in shrews, not only in biodiversity-rich regions but also in areas influenced by human activity. This study warrants further research to characterize and assess the clinical implications and risk of these viruses and the importance of shrews as reservoirs in European ecosystems.
