Distribution of antibiotic resistances in ST40 E. faecalis isolates
| Antibiotic resistance | Phenotype [%] | Resistance gene | Genotype [%] |
|---|---|---|---|
| Vancomycin (VanA-type) | 2.4 (1/42) | vanA | 2.4 (1/42) |
| Erythromycin | 21.4 (9/42) | erm(B) | 21.4 (9/42) |
| Tetracycline | 81.0 (34/42) | tet(M) | 81.0 (34/42) |
| Streptomycin (high-level) | 31.0 (13/42) | aadE | 33.3 (14/42) |
| Gentamicin (high-level) | 2.4 (1/42) | aac6′-aph2” | 0 (0/42) |
Broth microdilution assay was used to determine phenotypic antibiotic susceptibilities. Resistance genes were determined by PCR.
