Sir,
While screening the association of IS1216 with antibiotic resistance genes using primers IS1216F(55)1 and IS1216_upR (5'-CATCGTCATTCCTCCTGCTATC-3'), we found a 4.5 kb product from a tetracycline-resistant Streptococcus dysgalactiae subsp. equisimilis clinical isolate, NTUH-3089. DNA sequencing revealed the presence of the tet(S) gene flanked by IS1216 and other open reading frames (ORFs). Since the tet(S) gene has not been previously reported in this species, we further analysed the presence and the genetic environment of tet(S) in clinical isolates of S. dysgalactiae subsp. equisimilis.
First, we screened the presence of tet(S) by PCR from 188
