ETEST® PIPERACILLIN/ TAZOBACTAM  

ETEST® strips for AST testing of Piperacillin/Tazobactam

ETEST® PIPERACILLIN/TAZOBACTAM is a newly redesigned ETEST® strip to test antibiotic susceptibility with on-scale Minimum Inhibitory Concentration (MIC) for Piperacillin/Tazobactam, an important antibiotic for serious infections.

  • Exact MIC to reliably determine susceptibility
  • Fight resistance: detection of emerging strains
  • Calibrated against the reference broth microdilution (BMD)
  • Complementary testing to VITEK® 2 automated system

ETEST® P/T: Support optimized therapy

ETEST® PIPERACILLIN/TAZOBACTAM (ETEST® P/T) is a reliable solution for determining MIC of Piperacillin/Tazobactam of Enterobacteriaceae, Pseudomonas aeruginosa and Acinetobacter spp. By determining the exact Minimum Inhibitory Concentration (MIC), you gain more precise susceptibility information to support appropriate prescription and optimized Piperacillin/Tazobactam therapy for challenging situations.

Piperacillin/Tazobactam (Tazocin® and associated generics) is an association of a Piperacillin (ureidopenicillin) with broad spectrum anti-bacterial activity and Tazobactam (β-lactamase-inhibitor) expanding the antimicrobial spectrum. It is used to treat serious infections caused by Gram-negative bacteria including lower respiratory tract infections, urinary tract infections, intra-abdominal infections, bacterial sepsis and others. 

 

High performance susceptibility testing

ETEST® P/T performance characteristics for Piperacillin/Tazobactam have been established using comparative evaluations at external clinical sites. These studies have shown that ETEST® P/T MICs correlate with the CLSI method when MIC values from both procedures show an essential agreement (EA) of ≥ 90% within ± 1 dilution.
