Predominant (in > 2 isolates) acquired MDR patterns among E. faecalis and E. faecium isolated from conventional (CONV) and newly organic (ORG) poultry farms.a

|---|---|---|---|---|
| E. faecalis | ||||

| aE. faecalis is intrinsically resistant to LIN and streptogramin A (dalfopristin) (Dina et al. 2003), and E. faecium is intrinsically resistant to FLA; therefore, these species/drug combinations were excluded from the MDR analysis. | ||||
