Rodentibacter is a genus of Gram-negative bacteria in the family Pasteurellaceae. Members of this genus are facultatively anaerobic, non-motile, rod-shaped bacteria primarily associated with rodents, including laboratory mice and rats. The genus was first proposed in 2017 after phylogenetic studies showed that several former Pasteurella species and novel isolates formed a distinct clade.
Etymology
The name Rodentibacter is derived from the Latin word rodens (gnawing, referring to rodents) and the Greek word baktērion (small rod). It reflects both the host group (rodents) and the bacterial morphology (rod-shaped).
Characteristics
Rodentibacter species typically exhibit the following traits:
- Gram-negative
- Rod-shaped
- Facultatively anaerobic
- Non-motile
- Oxidase- and catalase-positive
They are part of the normal microbiota of rodents, particularly in the respiratory and urogenital tracts, but may also act as opportunistic pathogens.
Species
As of 2025, the genus Rodentibacter includes the following validly published species:[2]
- Rodentibacter abscessus
- Rodentibacter caecimuris (= Rodentibacter heylii)
- Rodentibacter haemolyticus
- Rodentibacter heidelbergensis
- Rodentibacter mrazii
- Rodentibacter myodis
- Rodentibacter pneumotropicus
- Rodentibacter rarus
- Rodentibacter ratti
- Rodentibacter trehalosifermentans
Rodentibacter heylii is now considered a later heterotypic synonym of Rodentibacter caecimuris.
Significance
Species of Rodentibacter are important in laboratory animal microbiology and veterinary medicine. Some species are part of the normal microbiota, while others may be implicated in infections, particularly in immunocompromised or stressed animals.
