Spirabiliibacterium

Spirabiliibacterium is a genus of Gram-negative, non-spore forming, non-motile bacteria in the family Pasteurellaceae. 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.^[1] 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 in birds.
