How this entity was disambiguated
This entity first appeared as the object of triple T11607622 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Moraxella
Moraxella is a genus of Gram-negative bacteria that commonly colonize the mucosal surfaces of humans and animals, with some species acting as important respiratory pathogens.
-
B.
Rhodococcus
Rhodococcus is a genus of Gram-positive, often soil-dwelling bacteria known for their ability to degrade a wide range of organic compounds, including environmental pollutants.
-

Streptococcus
Streptococcus is a genus of Gram-positive, often chain-forming bacteria that includes many species significant as human pathogens, such as those causing strep throat, pneumonia, and meningitis.
-
D.
Enterococcus
Enterococcus is a genus of Gram-positive, lactic acid bacteria commonly found in the gastrointestinal tracts of humans and animals, some species of which are notable as opportunistic pathogens and for their antibiotic resistance.
-
E.
Tsukamurella
Tsukamurella is a genus of Gram-positive, rod-shaped actinobacteria known for causing opportunistic infections in humans and being related to other mycolic acid–containing bacteria.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Actinomyces Description of subject: Actinomyces is a genus of filamentous, Gram-positive bacteria known for causing chronic, suppurative infections in humans and animals, particularly actinomycosis.
