Overview

  • Ornithobacterium rhinotracheale is a Gram-negative, non-spore-forming, microaerophilic, non-motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 37-39%. Ornithobacterium rhinotracheale is probably a rare gut coloniser. (Vandamme1994a; Hafez2010Bergey)



  • This organism has been recovered from human faeces and avian respiratory system. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: animal pathogen). It is an opportunistic pathogen. It's gut microbiome symbiotic status is unknown.

  • N/A

  • Although O. rhinotracheale has generally been considered nonhemolytic on blood agar, Tabatabai et al. documented the _-hemolytic activity of numerous strains, including O. rhinotracheale strain ORT-UMN 88, and suggested that a hemolysin-like protein may function as a virulence factor [PMID: 25780507]

  • GutFeeling KnowledgeBase COMMENTS [Website]

    Ornithobacterium rhinotracheale strain ORT-UMN 88 is a Gram-negative, pleomorphic, rod-shaped bacterium and an etiologic agent of pneumonia and airsacculitis in poultry. It is a member of the family Flavobacteriaceae of the phylum Bacteroidetes. O. rhinotracheale strain ORT-UMN 88 was isolated from the pneumonic lung of a turkey in 1995. It was the isolate first used to experimentally reproduce disease in turkeys and has since been the focus of investigations characterizing potential virulence factors of the bacterium.
