Etest® is a quantitative technique for determination of antimicrobial susceptibility of both non-fastidious Gram

negative and Gram positive aerobic bacteria such as Enterobacteriaceae, Pseudomonas, Staphylococcus, and

Enterococcus species and fastidious bacteria, such as anaerobes, N. gonorrhoeae, S. pneumoniae, Streptococcus and

Haemophilus species. The system comprises a predefined antibiotic gradient which is used to determine the

Minimum Inhibitory Concentration (MIC), in μg/mL, of different antimicrobial agents against microorganisms as

tested on agar media using overnight incubation.

Etest® Ceftolozane / Tazobactam has been shown to be active against the Gram negative aerobic microorganisms

listed below, according to the FDA label for this antimicrobial agent:

Active both in vitro and in clinical infections:

Enterobacter cloacae

Escherichia coli

Klebsiella oxytoca

Klebsiella pneumoniae

Proteus mirabilis

Pseudomonas aeruginosa

The following in vitro data are available, but clinical significance is unknown:

Citrobacter koseri

Morganella morganii

Proteus vulgaris

Providencia rettgeri

Providencia stuartii

Serratia liquefaciens

Serratia marcescens

Indications for use as stated in the FDA summary.
