Infection Control Today's Topic of the Month for April: Celebrating Sterile Processing
ICT: In the context of sterile processing, can you share Agilent's approach to ensuring the reliability and accuracy of results in the testing of water, food, and pharmaceuticals, considering the global scale and diverse environments involved?
AC: Agilent ensures the reliability and accuracy of results in testing water, food, and pharmaceuticals by providing high-quality instruments and trusted solutions. Maintaining sterility is important to ensure that the products are free from viable microorganisms that can cause harm to human health. Various methods and technologies can be used to ensure sterility, including:
- Bacterial endotoxin testing
FDA regulations require that raw materials used in parenteral drugs be tested for endotoxin levels. Agilent BioTek Absorbance Readers are proven platforms for performing bacterial endotoxin LAL assays. Bacterial endotoxins are lipopolysaccharides (LPS) generally found in the outer membrane of gram-negative bacteria, such as Escherichia coli. They are widely present in our environment and cause human effects ranging from fever to hemorrhagic stroke.
https://www.agilent.com/en/solutions/cell-analysis/toxicology-research/endotoxin-analysis-lal-assay - Monitoring the growth of bacteria
The BioTek LogPhase 600 microbiology reader is designed for measuring microbial growth curves in up to four standard 96-well microplates. This microbiology plate reader features purpose-built robust shaking and consistent temperature controls, which are critical to optimal bacteria and yeast cell growth.
https://www.agilent.com/en/product/microplate-instrumentation/microplate-readers/multiplate-absorbance-reader/biotek-logphase-600-microbiology-reader-1623185 - Bacterial detection in food
Foodborne illness traced to fruits and vegetables has increased research on methods for ensuring end-product safety. The Agilent BioTek ELx800 absorbance microplate reader and BioTek ELx50 microplate strip washer are used in a low-cost semi-automated method to detect Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella enterica Typhimurium from a 5% organic load of lettuce wash.
www.agilent.com/cs/library/applications/concentration-detection-lettuce-wash-5994-2547EN-agilent.pdf - Bacterial detection in environmental water
NovoCyte flow cytometers provide a high sensitivity of detection for detecting and analyzing microbes in environmental water. Traditional bacterial identification methods are based on observations of the morphology of single cells or colony characteristics when grown on agar. However, the microbes grown on an agar medium with visible colonies are less than 1% of the total, and most bacteria, though present and active, are not efficiently cultured.
www.agilent.com/cs/library/applications/application-detection-bacteria-environmental-waters-novocyte-5994-2114en-agilent.pdf - Evaluating bacterial biofilms
Bacteria prefer to live a communal lifestyle encased in a 3D extracellular matrix composed of a mix of extracellular polymeric substances (EPS). These bacterial biofilms are responsible for human and livestock diseases and can cause industrial air and water handling systems fouling. Agilent offers several in vitro methods to study biofilm systems, including biochemical, imaging, and cellular impedance assays.
