Isolated from the human vagina, and associated with human infections (lung, ear, eye, genital tract and others). Pathogen or commensal.
Fastidious (hard to grow). HACEK organism that can cause heart inflammation and infection.
Has been found as a sexually transmitted pathogen in men who have sex with men1.
Can produce acid from mannose. Not favoured by temperatures over 35C.
