Compact Dry ETB
Art. No.: HS9431 / HS9432
Usage of Compact Dry ETB is a simple and safe test procedure for determination and quantification of Enterobacteria in foods, cosmetics or raw materials – as well as pharmaceutical raw materials. The ready-to-use plates consist of a special 50 mm diameter petri dish containing a detection specific nutrient pad.
The Enterobacteriaceae are gram-negative, rod-shaped bacteria which are typically 1 – 5 µm in length. They are facultative anaerobes and most are motile, but non-motile genera exist as well. Enterobacteriaceae can’t build oxidase and can be distinguished from similar genera by this criterion. Enterobacteriaceae are a normal part of the gut flora which is found in the intestinal tract of humans and animals. They are also spread widely in the environment (e.g. soil, water). Some genera are pathogenic and can cause serious diseases. Genera of Enterobacteriaceae are: Cedecea, Citrobacter, Enterobacter, Escherichia, Hafnia, Klebsiella, Kluyvera, Morganella, Proteus, Rahnella, Salmonella, Serratia, Shigella and Yersinia.
The ready-to-use, chromogenic Compact Dry plates are suitable for in-process controls as well as controls of finished products. With the optional additional product Promedia ST-25 swab test (Z0302) Compact Dry plates may also be used for surface sampling and therefore applied for quantitative hygiene monitoring even at surfaces which are difficult to reach.
- Compact Dry ETB is therefore an extremely easy-to-use method and also convincing due to the high time saving; a confirmation test is also not necessary.
