Emergence of the zoonotic bacterium Necropsobacter rosorum in nutria Myocastor coypus with implications for wildlife and human health.

ABSTRACT: The nutria (Myocastor coypus), a semi-aquatic rodent native to South America, poses significant ecological and agricultural threats as an invasive species in France, where it continues to proliferate despite sustained control efforts. A fatal case of pneumonia in a nutria from Marseille (France) prompted a microbiological investigation that led to the isolation, taxonomic classification, genomic characterization, and phylogenetic analysis of Necropsobacter rosorum. Whole-genome sequencing of the N. rosorum strain RG01 revealed a genome size of 2,505,657 base pairs and 2303 predicted open reading frames, showing high similarity to other publicly available N. rosorum genomes. Comparative pan-genomic analysis indicated a high level of genomic conservation among N. rosorum strains. The presenc
