Abstract
ABSTRACT
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 49175
T
)
Abiotrophia defectiva
(ATCC 49176
T
), and
Granulicatella elegans
(formerly
Abiotrophia elegans
) (DSM 11693
T
). 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 α- and β-galactosidase; production of β-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.
