''. It was established in 2019 following the reclassification of previously unclassified ''Pasteurella''-like organisms grouped under Bisgaard taxon 14 and 32. The genus includes species primarily isolated from the respiratory tract of birds.

Taxonomy

The genus ''Spirabiliibacterium'' was proposed by Bisgaard and Christensen in 2019 based on a combination of phenotypic, biochemical, and whole-genome sequence analyses. The genus currently includes the following species: * ''Spirabiliibacterium mucosae'' * ''Spirabiliibacterium pneumoniae'' * ''Spirabiliibacterium falconis'' The type species is ''Spirabiliibacterium mucosae''. The name is derived from the Latin ''spirabilis'' (breathable) and ''bacterium'', referring to its association with

respiratory infections Respiratory tract infections (RTIs) are infectious diseases involving the lower or upper respiratory tract. An infection of this type usually is further classified as an upper respiratory tract infection (URI or URTI) or a lower respiratory tract ...
