Chryseobacterium spp. vulvovaginal and urinary tract infections

Chryseobacterium species are a known human pathogen with low virulence, but very resistant to antibiotics, making it a nuisance in hospitals. Anyone with severe underlying disease, catheters or other devices is at risk of infection by Chryseobacterium species, but generally, this bacteria stays clear of the vagina and urinary tract in women.

Chryseobacterium indologenes was the cause of one case study whereby a 19-year-old woman was admitted to hospital with a urinary tract infection. 

Another species, Chryseobacterium gleum, was found in a high vaginal swab in England. 

Chryseobacterium form yellow-orange pigments, and can be found in many areas from water to soil to fish to humans​1​.
