Granulicatella species, formerly known as nutritionally variant streptococci, cause a variety of @entity281 , primarily @entity884 . We report the first culture-proven case of a Granulicatella species causing @entity5414 . A 68-year-old female presented with knee @entity158 and @entity4 . She was initially evaluated with arthrocentesis and arthroscopy, but no organism was identified. Her @entity158 improved after a brief course of antibiotics but recurred 3 months later. She underwent repeat arthrocentesis, with direct inoculation of synovial fluid into blood culture bottles. Granulicatella adiacens was recovered from both bottles. She was treated with @entity7048 for 4 weeks combined with @entity801 for the first 2 weeks. Her knee @entity158 and @entity4 resolved without evidence of recurrence. Granulicatella should be considered in cases of @entity5414 with initially negative synovial fluid cultures. Inoculation of blood cultures bottles with synovial fluid may increase the diagnostic yield for these species.

XXXX caused by Granulicatella adiacens: diagnosis by inoculation of synovial fluid into blood culture bottles.
