Otariodibacter oris is a Gram-negative bacterial species in the family Pasteurellaceae and the only known member of the genus Otariodibacter. It was first isolated from the oral cavity of a Californian sea lion (Zalophus californianus) at the Copenhagen Zoo in Denmark in 2007.[1]
Etymology
[edit]The binomial name Otariodibacter oris is derived from:
- Otario-, referring to the marine mammal family Otariidae (eared seals such as sea lions),
- -di-, meaning “from” or “of”,
- -bacter, from Greek *baktērion*, meaning “small rod”.
The species epithet oris is derived from Latin *os, oris*, meaning "mouth", referring to the site of isolation.
Thus, the full name means "rod-shaped bacterium from the mouth of an otariid (sea lion)."
Characteristics
[edit]Otariodibacter oris exhibits the following traits:
- Gram-negative
- Rod-shaped
- Non-motile
- Facultatively anaerobic
It is positive for both catalase and oxidase activity. The bacterium grows on blood agar under aerobic and microaerophilic conditions.
Habitat
[edit]Otariodibacter oris was isolated from an oral swab of a captive Californian sea lion (Zalophus californianus). It is presumed to be a commensal species within the oral microbiome of marine mammals.
Type strain
[edit]The type strain of Otariodibacter oris is:
- DSM 23800
- Also referred to as strain T-1
- Deposited in the Deutsche Sammlung von Mikroorganismen und Zellkulturen (DSMZ)
