Distribution of minimum lethal concentrations (MLCs) of tinidazole and metronidazole, STD Surveillance Network, 2009–2010 (n = 538). Susceptibility to metronidazole and tinidazole are defined as MLC <25 μg/mL, low-level resistance as MLC 50–100 μg/mL, moderate-level resistance as MLC 200 μg/mL, and high-level resistance as MLC >400 μg/mL.
