MTS™ (MIC Test Strip) Levofloxacin 0.002-32 pg/mL is a quantitative method intended for the in vitro determination of antimicrobial susceptibility of bacteria. MTS™ consists of specialized paper impregnated with a pre-defined concentration gradient of an antimicrobial agent, which is used to determine the minimum inhibitory concentration (MIC) in pg/mL of antimicrobial agents against bacteria as tested on agar media using overnight incubation and manual reading procedures.

MTS™ [evotloxacin at concentrations of 0.002 - 32 pug/mL should be interpreted at 16-20 hours of incubation.

MTS™ Levotloxacin can be used to determine the MIC of levofloxacin against the following bacteria.

Levofloxacin has been shown to be active both clinically and in vitro against these bacterial species according to the FDA drug approved label:

Gram-negative bacteria

Enterobacter cloacae

Escherichia coli

Klebsiella pneumoniae

Proteus mirabilis

Pseudomonas aeruginosa
