*Erythromycin resistance was tested at 5 μg/ml. †Vancomycin resistance was tested at 10 μg/ml. ‡Two sets of primers were used to detect the cas genes (cas1 and csn1). §This set of primers amplifies the junction between EF0672 and EF0673 where the CRISPR1 locus is inserted in OG1RF. ¶CC2. # Ruiz-Garbajosa P. (Spain), Jensen L. (Denmark), Gaastra W. and Mevius D. (Netherland), and Kawalec M. (Poland).
