One hundred one isolates of nutritionally variant streptococci from
97 patients were phenotypically characterized and compared with the
type strains of Granulicatella adiacens (formerly
Abiotrophia adiacens) (ATCC 49175T)
Abiotrophia defectiva (ATCC 49176T), and
Granulicatella elegans (formerly Abiotrophia
elegans) (DSM 11693T). Of the isolates, 55 and 43 resembled G. adiacens and
A. defectiva, respectively, while 3 strains resembled G. elegans. Phenotypic characteristics useful in differentiating between species within the
genera Granulicatella and Abiotrophia
(G. adiacens, G.
elegans, Granulicatella balaenopterae,
and A. defectiva) were production of

and
-galactosidase; production of
-glucuronidase; hippurate hydrolysis; arginine dihydrolase activity; and acid production from
trehalose, sucrose, pullulan, and tagatose. From the reports submitted
with the specimens, the clinical diagnosis was endocarditis in 58% of
patients and septicemia or bacteremia in 26% of patients.
