Microbiology experts, Oxoid Limited, have extended their range of Quality Control (QC) organisms to include a series of specialised kits designed specifically for the water industry. Water Bugs and Wkits are ready-to-use, preserved suspensions of environmental Quality Control micro-organisms that simulate actual water/waste water samples.

Water Bugs and Wkits are ideal for the quality control testing of water testing techniques, such as membrane filtration, most probable number (MPN), standard presence/absence (P/A) and chromogenic procedures, including MMO/MUG.

Water Bugs are quantitative QC organisms supplied in Quanti-Cult vials, each containing an inoculum of less than 50 CFUs to mimic water samples. Wkits are a combination of Water Bugs and qualitative Culti-Loops (ready-to-use, disposable inoculating loops containing preserved, viable micro-organisms). The gentle gel-preservation technique used to stabilise the micro-organisms enhances recovery and reproducibility, whilst the convenient, ready-to-use formats ensure speed and ease of use.

The range of micro-organisms available in these kits include Enterobacter cloacae ATCC 13047, Escherichia coli strain C1, Klebsiella pneumoniae strain C6, Proteus mirabilis ATCC 12453, Pseudomonas aeruginosa ATCC 27853 and Enterococcus faecalis ATCC 29212.

Water Bugs and Wkits are manufactured to the highest standard in ISO-certified facilities and a Certificate of Quality is supplied with each micro-organism.
