Bacteraemia due to Extibacter muris in an Immunocompetent Patient: First Case, Review and a Phylogenetical Analysis

Extibacter muris is a recently identified anaerobic Gram-positive rod belonging to the Lachnospiraceae family. Initially identified in the murine gut microbiota, it has recently been identified in the human gut microbiota. This article presents the case of an immunocompetent patient who was hospitalized with symptoms of sepsis. E. muris bacteraemia was diagnosed. This species was identified through 16S rRNA gene sequencing after comparison with published sequences. However, further studies are necessary to assess the impact of E. muris on the infection and to investigate potential clinical factors influencing these infections.
