Endocarditis (see Endocarditis, [[Endocarditis]]): reported with Granulicatella adiacens and Granulicatella elegans
Approximately 5% of infective endocarditis cases are caused by nutritionally variant streptococci strains
Treatment/Prognosis
Clinical course with nutritionally variant streptococci strains is often more severe than that in cases caused by enterococci or viridans streptococci [MEDLINE]
Infections are difficult to treat: relapse rate of 41%, despite appropriate antibiotics [MEDLINE]
