Susceptibilities of oral and nasal isolates of Streptococcus mitis and Streptococcus oralis to macrolides and PCR detection of resistance genes

Antimicrob Agents Chemother. 2000 Apr;44(4):1078-80. doi: 10.1128/AAC.44.4.1078-1080.2000.

Abstract

The susceptibility of viridans group streptococci to macrolides was determined. Thirteen isolates (17%) were resistant to erythromycin. Five strains carried an erm gene that was highly homologous to that in Tn917. Four strains had mefE genes that coded erythromycin efflux ability.
