Exercitatus is a genus of Gram-negative bacteria belonging to the family Pasteurellaceae. It was first described in 2023 following the taxonomic reclassification of bacterial strains previously grouped within Bisgaard taxa 6 and 10.[1]
Etymology
[edit]The name Exercitatus derives from the Latin word meaning "trained" or "disciplined," referring metaphorically to the careful, systematic classification process involved in defining this genus.[1]
Characteristics
[edit]Members of the genus Exercitatus exhibit the following traits:[1]
- Gram-negative
- Facultatively anaerobic
- Non-motile
- Rod-shaped or pleomorphic
- Oxidase-positive
- Catalase-positive
- Grow on blood agar, forming small, non-haemolytic colonies
Habitat and isolation
[edit]Bacteria belonging to the genus Exercitatus have been isolated predominantly from birds, notably from respiratory tract samples. Prior to their formal description, these bacteria were referred to as Bisgaard taxa 6 and 10.[1]
Taxonomy
[edit]The type species of the genus is Exercitatus varius.[1]
