Multiplex PCR for simultaneous detection of macrolide and tetracycline resistance determinants in streptococci

Resistance to macrolides and tetracyclines is increasing among streptococci and co-occurs as their resistance determinants are carried on the same mobile element. We developed a multiplex PCR to facilitate simultaneous and specific detection of resistance determinants for both macrolides [erm(A), erm(B), and mef(A/E)] and tetracyclines [tet(M), tet(O), tet(K), and tet(L)] in streptococci.
