Thermo Scientific™ Oxoid™ Aztreonam-Avibactam Antimicrobial Susceptibility Discs
Manually determine the antibiotic susceptibility of microorganisms using disc diffusion methods with consistently reliable, industry-leading quality Thermo Scientific™ Oxoid™ Aztreonam-Avibactam Antimicrobial Susceptibility Discs
The drug aztreonam-avibactam has been designed to address infections caused by aerobic Gram-negative organisms that are resistant to other antibiotics due to the production of beta-lactamase enzymes. Aztreonam-avibactam is especially valuable for infections caused by organisms producing metallo-beta-lactamases (MBLs), which are resistant to many other beta-lactam antibiotics.
Perform susceptibility testing of multi-drug resistant aerobic Gram-negative organisms using Aztreonam-Avibactam Antimicrobial Susceptibility Discs.
Features include:
- Meets EUCAST and CLSI recommended breakpoints
- Produces quality results in line with the rest of the Oxoid disc portfolio as demonstrated over 3 EUCAST disc quality studies
- Easy to use: shatterproof spring-loaded cartridges, easy-to-read labelling, and end-of-cartridge indicators
- Long-term stability ensured: each cartridge is individually sealed with a desiccant to maintain a moisture level of <2%
- Accurate and reproducible: manufactured under stringent quality standards including BS EN ISO 9001:2008, ISO 13485:2003 and FDA 21 CFR part 820, with comprehensive quality control testing
- Trusted supplier: over 35 years of experience in disc development and manufacture
Aztreonam-Avibactam has been shown to be effective against:
- Escherichia coli
- Klebsiella pneumoniae
- Klebsiella oxytoca
- Enterobacter cloacae complex
- Citrobacter freundii complex
- Serratia marcescens
Disc diffusion not only categorizes resistant, intermediate, and sensitive organisms through qualitative results but also provides a visual indication of the following:
- Inoculum level
- Presence of contamination
- Resistant mutants
- Beta-lactamase activity
- Antagonism and synergy between antibiotics
