Thermo Scientific™ Oxoid™ Piperacillin-tazobactam TZP, Antimicrobial Susceptibility Discs, 110μg

The Thermo Scientific™ Oxoid™ Piperacillin/Tazobactam Antimicrobial Susceptibility Discs are precision-engineered tools used in manual antimicrobial susceptibility testing (AST), particularly by the Kirby-Bauer disc diffusion method. Each disc contains 110 μg of a fixed combination of Piperacillin, a broad-spectrum ureidopenicillin, and Tazobactam, a β-lactamase inhibitor, enabling reliable detection of bacterial resistance mechanisms such as extended-spectrum β-lactamases (ESBLs).

Designed to deliver clear, reproducible zone-of-inhibition results, these discs support semi-quantitative in vitro diagnostics by providing key visual indicators of antimicrobial activity. The discs are housed in spring-loaded, shatterproof cartridges with individually sealed desiccant barriers to maintain optimal moisture levels (<2%), ensuring consistent potency and long-term stability.

These discs are ideal for use in clinical microbiology laboratories, antimicrobial resistance surveillance programs, and infection control workflows.

Key Features and Benefits

• Potent Dual-Agent Disc (110 μg): Combines 100 μg Piperacillin and 10 μg Tazobactam for synergistic inhibition of resistant Gram-negative pathogens.
• Ease-of-Use: Convenient shatterproof cartridges with easy-to-read labeling and end-of-cartridge indicators streamline testing workflows.
• Stable & Reliable: Moisture-controlled cartridges ensure extended shelf life and consistent zone diameters.
• Diagnostic Utility: Enables detection of β-lactamase-producing bacteria and supports resistance mechanism profiling (e.g., ESBL, AmpC).
• Compliant with Global Standards: Conforms to CLSI, EUCAST, and BSAC guidelines for antimicrobial susceptibility testing.
• Versatile Compatibility: Suitable for use with a wide range of Enterobacteriaceae, Pseudomonas spp., and Acinetobacter spp.

Intended Use

For in vitro diagnostic use in determining the susceptibility of bacteria to Piperacillin/Tazobactam. Recommended for use in laboratories performing disk diffusion susceptibility testing on pure agar-grown cultures.

Applications

• Hospital-acquired and multidrug-resistant infection surveillance
• Gram-negative resistance detection (e.g., Pseudomonas, Enterobacteriaceae)
• Microbiology laboratories and clinical diagnostic testing
• Antimicrobial stewardship programs
