Abstract
ABSTRACT
In the present report we describe the characteristics of 189 antimicrobial-resistant
Streptococcus agalactiae
isolates from bovine (38 isolates) and human (151 isolates) sources. All the strains were resistant to tetracycline (TET), and 16 (8.5%) were also resistant to erythromycin, corresponding to 23.7% of the TET-resistant bovine isolates and 4.6% of the TET-resistant human isolates. The
tet
(O),
erm
(B), and
mreA
resistance-related genes, as well as the
bca
and
scpB
virulence-related genes, were the most frequent among the bovine isolates, while the
tet
(M),
erm
(A),
mreA
,
bca
,
lmb
, and
scpB
genes were the most prevalent among the isolates from humans. Although a few major clusters were observed, pulsed-field gel electrophoresis results revealed a variety of profiles, reflecting the substantial genetic diversity among strains of this species isolated from either humans or bovines.
