Our range of products for water testing includes dehydrated and prepared media, membrane filters, qPCR assays for Legionella, quality control organisms, as well as the equipment you need to deliver reliable results.
Conveniently prepare water samples when isolating and enumerating Legionella species according to EN ISO 11731 water quality testing specifications using Thermo Scientific Legionella Acid Buffer Solution. The convenient high-quality, transparent PET bottle has a leak-proof screw top made of PET and is lighter and more shatter-resistant than glass, making it better for handling in the laboratory as well as shipping.
To support your laboratory’s water testing processes, we have added Thermo Scientific Culti-Loops Quality Control Legionella anisa NCTC 11974 (WDCM 00106) to our quality control testing organism range. Culti-Loops Quality Control organisms enable quick and safe preparation of cultures for QC testing with ready-to-use, disposable inoculation loops containing gel-stabilised micro-organisms.
Legionella anisa is the second most often isolated Legionella species from water samples, after Legionella pneumophila.

Put colonies that grew under anaerobic conditions onto filter paper and add 2-3 drops of phosphateacid. All colonies that turn purple within 3-4 minutes are confirmed positive. |
*ATTENTION: Alternatively, a thin layer (approximately 5 mL to 10 mL) of molten TSC Agar (TV5204G TSC Agar Base), as an overlay on the filter can be used. Allow to solidify before anaerobic incubation. This method may enhance the blackening of the colonies. Medium without cycloserine; e.g. TV5204G TSC Agar Base, 20 mL.
Melt agar in a water bath at 95°C for approx. 10-15 minutes |
Cool medium to 45°C |
Shake tube carefully and pour a thin layer of molten agar |
