Characterisation of a novel integrative and conjugative element ICESsD9 carrying erm(B) and tet(O) resistance determinants in Streptococcus suis, and the distribution of ICESsD9-like elements in clinical isolates
A novel integrative and conjugative element (ICE) conferring resistance to MLSB and tetracycline was identified. It can transfer by conjugation into Streptococcus suis and Enterococcus faecalis with high frequency. First description of integration of an ICE of the ICESa2603 class into E. faecalis chromosome. Presenting potential mechanism leading to multidrug resistance in S. suis isolates.
