VITEK® 2 Gram Negative Ceftriaxone is designed for antimicrobial susceptibility testing of Gram-negative bacilli.

VITEK® 2 Gram Negative Ceftriaxone is a quantitative test intended for use with the VITEK® 2 and VITEK® 2 Compact Systems as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents. Ceftriaxone has been shown to be active against most strains of the microorganisms listed below, according to the FDA label for this antimicrobial.

Active in vitro and clinical infections:

Enterobacter aerogenes Escherichia coli Klebsiella oxytoca

Klebsiella pneumoniae Proteus mirabilis Serratia marcescens

In vitro data available but clinical significance is unknown:

Citrobacter koseri (formerly Citrobacter diversus) Citrobacter freundii Shigella species

Providencia species (including Providencia rettgeri) Salmonella species (including Salmonella typhi)

The VITEK® 2 Antimicrobial Susceptibility Test (AST) is intended to be used with the VITEK® 2 System for the automated quantitative or qualitative susceptibility testing of isolated colonies for the most clinically significant aerobic gram-negative bacilli, Staphylococcus spp., Enterococcus spp., Streptococcus spp., S. pneumoniae, and clinically significant yeast.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
