Ja. Jacobs et al., Prevalence of macrolide resistance genes in clinical isolates of the Streptococcus anginosus ("S-milleri") group, ANTIM AG CH, 45(8), 2001, pp. 2375-2377
Twenty-two unrelated erythromycin-resistant anginosus group strains (3.2% r
esistance rate) were assessed for mechanisms of resistance. Streptococcus a
nginosus accounted for 16 of the 22 isolates. Fifteen isolates harbored the
erm(B) gene. The erm(TR) and the mef(E) genes were carried by two isolates
each. In three isolates, none of these resistance genes was detected by PC
R.
