Table 2. Antibiotic resistance of S. epidermidis strains
Note. R — resistant strain, S — sensitive strain.
Table 3. Resistance genes in S. epidermidis
Note. Symbols + and – represent the presence and absence of the resistance gene in the strain genome. Gene aacA-aphD  mediates resistance to amikacin, gentamycin, kanamycin, and tobramycin; gene aadD mediates resistance to amikacin, kanamycin, neomycin and tobramycinl; aphA mediates resistance to kanamycin and neomycin; blaZ — to penicillins; mecA — to beta-lactam antibiotics; fusB and fusC to fusidic acid; vanA, vanB, and vanZ  to vancamycin; lnu(A), vga(A), and vga(B) — to licosamides (clindamycin); msr(A) and mph(C) — to macrolide antibiotics (erythromycin); erm(A), erm(B), and erm(C) — to macrolide antibiotics and lincosamides; vat(B) — to streptogramin B; tet(M) and tet(K) — to tetracycline; dfr(G) and dfr(K) — to trimethoprim.
