MeSH Oropharynx

The Oropharynx (oral part of the pharynx) reaches from the Uvula to the level of the hyoid bone.

It opens anteriorly, through the isthmus faucium, into the mouth, while in its lateral wall, between the two palatine arches, is the palatine tonsil.

Normal oropharyngeal flora

Fusobacterium

Although older resources have stated that Fusobacterium is a common occurrence in the human oropharynx, the current consensus is that Fusobacterium should always be treated as a pathogen. [1]

HACEK organisms

The name is formed from their initials:[2]

All of these organisms are part of the normal oropharyngeal flora, which grow slowly, prefer a carbon dioxide–enriched atmosphere and share an enhanced capacity to produce endocardial infections, especially in young children.

Actinomyces

Actinomyces species that cause human disease do not exist freely in nature but are normal flora of the oropharynx.
