Rapid Microbiological Methods for Water Testing - a rapidmicrobiology Special Focus


Microbiological testing of water is crucial for ensuring its safety and quality, whether that is endotoxin or sterility testing of Water for Injection (WFI), E.coli, or Enterococci in potable or Legionella in cooling tower water. Even enumeration of coliphages can be easily achieved.

Several new technologies have emerged in recent years to improve the efficiency and accuracy of these tests. These normally involve some automation of the testing process and may also involve novel approaches using molecular diagnostic technologies. Explore some of the latest options In this rapidmicrobiology special focus on rapid microbial methods (RMM) for water.

Traditional methods for monitoring microbial water quality, such as measuring indicator bacteria like fecal coliforms, Escherichia coli, and Enterococci, are still widely used. SGL can supply high-quality culture media (ISO/IEC 17025) plus for Legionella testing their GVPC agar (ISO 11731 compliant) has a 6-month shelf life.  Bio-rad offer a handy Water Safety and Quality Reference Guide to download, showcasing both their range of traditional chromogenic media and real-time PCR options for water testing with 'at-a-glance' easy-to-understand workflows for alternative and standard methodologies.

Diamidex MICA is a high-end micro colony counter that offers a range of testing parameters including Legionella, Pseudomonas, and bioburden with an E.coli option coming soon. Using a fusion of online biosensors and traditional culture-based techniques, the MICA can achieve 250 analyses per 8-hour shift with results reported in CFU.

Discover applications for automated cytometry-based SCAN RDI and Red One such as sterility testing of Water for Injection (WFI), bioburden, Direct Viable Counts (DVC), and even E.coli

FujiFilm Wako PYROSTAR™ Neo offers a sensitive and specific assay for endotoxin in WFI, using reagents that are 100% free of horseshoe crab blood.

Get actionable same-day results for somatic coliphage counts using the Bluephage ENUMERA kit, which only needs 20 minutes of hands-on time. Also for virus detection, the PREvalence ddPCR SARS-CoV-2 Wastewater Quantification Kit includes all reagents needed to detect the virus in wastewater and automated analysis software. 

Need to test outside of a lab or 'out of hours' the Tecta® recently acquired by IDEXX is a complete, self-contained system, providing rapid evidence of bacterial contamination, either within or outside of a traditional laboratory setting.
