Granulicatella adiacens is a catalase-negative, oxidase-negative, facultatively anaerobic, Gram-positive coccus [1]. This bacterium is considered nutritionally variant streptococci (NVS) because of its requirement for pyridoxal, L-cysteine, or additional nutrients, such as sulfhydryl compounds, for growth [2]. G. adiacens can grow well on culture medium containing these required nutrients. G. a...
