In the report we try to indicate that this antibiotic:
- may be used, S (no resistance traits/mechanisms) or
- cannot be used, R (with resistance traits).
Another binary terminology may be employed.
The term I is employed only when a strain or a group of strains without R-traits is not sufficiently sensitive to concentrations obtaining after routine doses of antibiotics ( L 19). The term I does not indicate indeterminate or unknown.
