Detection of antimicrobial resistance, transposon and plasmid genes Tetracycline resistance genes tet(M), tet(O), tet(L), tet(K), tet (W), macrolide resistance genes erm(B), mef(A) and intTn916 had been detected by PCR as described by other people [35?8]. For the detection of tet(40) and also the lincosamide resistance genes lsa (E) and lnu(B), primer pairs tet40-up/tet40-dn ( 5 - C TA C C T G C T G T T C C G AT T T G T C a n d 5-TGATGAAGGTATCACCGCAACC), lsaE-up/lsaE-dn ( 5 - T AT G C G T AT T C C G G C A AT AT A A G a n d 5-AACGGCTTCCTGATGTCTTG) and lnuB-up/lnuB-dn ( 5 - C G T G G G G A AT T T C AT T T C C T T T C a n d 5-CGTTGATTCCCATCAACCATAG) were applied, respectively.

The presence of rep1 and rep2 genes, characteristic for broad-host variety streptococcal and enterococcal plasmids, was tested utilizing primers andconditions proposed within the Gram(+) plasmid typing scheme [39]. The reppBM407 gene [18] was searched by PCR with primers rep407-up/rep407-dn (5-GTATCGCACGTA TTCCTCGTG and 5-CATAATAGCCTTTTCCCCACGA). The -- and relBE genes of plasmid toxin ntitoxin systems (TAS) had been searched for as previously described [40]. The repA gene, particular for ICESsuSC84 and ICESsuBM407-2 [18], was detected with consensus primers repA_up/repA_dn (5-TTAAGGTAGCCTACGCGGTTTTA and 5-GTC GTCTCAGTTGCTTRGTCC). DNA from previously characterised clinical isolates of Streptococcus agalactiae, E. faecalis and Enterococcus faecium from our collection have been used as constructive controls for the detection of tet(M), tet(O), tet (L), tet(K), tet(W), erm(B), mef(A), intTn916, rep1, rep2, -- and relBE.15).
