Granulicatella adiacens is a fastidious Gram-positive cocci (pairs, chains) and is part of the nutritionally variant streptococci (NVS). [2] [3] [4] Like other constituents of the NVS, it can cause bacteremia and infective endocarditis (IE), with significant morbidity and mortality.
Aerococcus urinae is a member of the bacterial genus Aerococcus.The bacterium is a Gram-positive, catalase-negative coccus growing in clusters. Isolates of this genus were originally isolated in 1953 from samples collected in the air and dust of occupied rooms and were distinguished by their tetrad cellular arrangements. [2]
Finegoldia is a genus of Gram-positive bacteria.They are anaerobic cocci of the class Clostridia, with Finegoldia magna being the type species. [1] F. magna was formerly known, along with several other Gram-positive anaerobic cocci (GPACs), as Peptostreptococcus magnus, but was moved into its own genus in 1999.
These bacteria are Gram-positive and strictly anaerobic. [2] [3] [4] The genus Anaerococcus was proposed in 2001. [2] [4] Its genome was sequenced in August 2009. The genus Anaerococcus is one of six genera classified within the group GPAC (Gram-Positive Anaerobic Cocci). [5]
Enterococcus casseliflavus are facultative Gram-positive cocci. They are catalase negative and produce pyrolidonyl arylamidase. They are catalase negative and produce pyrolidonyl arylamidase. They are able to produce acid from many sugars, including L-Arabinose, gluconate, inulin, mannitol, melibiose, trehatol, and xylitol. [ 2 ]
Anaerobic gram-positive cocci and microaerophilic streptococci are most frequently found in aspiration pneumonia, empyema, lung abscesses, and mediastinitis. These bacteria account for 10-20% of anaerobic isolated recovered from pulmonary infections. It is difficult to obtain appropriate culture specimens.
Enterococci are Gram-positive cocci that often occur in pairs or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. [2] Two species are common commensal organisms in the intestines of humans: E. faecalis (90–95%) and E. faecium (5–10%).
Enterococcus faecalis – formerly classified as part of the group D Streptococcus system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans. [1] [2] Like other species in the genus Enterococcus, E. faecalis is found in healthy humans and can be used as a probiotic.
