Detection and Genomic Characterization of Novel Mammarenavirus in European Hedgehogs, Italy

Emerg Infect Dis. 2025 Jan;31(1):155-159. doi: 10.3201/eid3101.241084.

Abstract

Mammarenaviruses are noteworthy zoonotic pathogens, and the main reservoirs are rodent species. We report the detection of a novel mammarenavirus in 6/183 (3.3%) in necropsied European hedgehogs (Erinaceus europaeus) collected in Italy. The whole-genome sequence obtained for 4 strains revealed a marked genetic diversity but a monophyletic origin.

Keywords: Arenaviridae; European hedgehog; Italy; mammarenaviruses; viruses; zoonoses.
