Breakpoints.

¹Number of strains at this MIC.

²MIC ≥1 μg/mL are considered resistant for chlorhexidine (Leelaporn et al., 1994).

³The entries in bold indicate resistance.

⁴MIC >2 μg/mL are considered resistant for triclosan (Heath and Rock, 2000).

⁵MIC <30 μg/mL are susceptible, MIC from 30–50 μg/mL are low-level resistant, and MIC >μg/mL are considered resistant for BKC (Sidhur et al., 2002b).

⁶This entry is a disinfectant component.
