Hvad er coliforme bakterier? Coliforme bakterier er enten bevægelige eller ikke-bevægelige Gram-negative, ikke-sporedannende Baciller med -galactosidase, der skaber syrer og gasser ved deres optimale væksttemperatur på 35-37°C. Aerobe og fakultative aerobe er et almindeligt tegn på dårlig hygiejnisk kvalitet i mad, mælk og vand.Definition. A group of bacteria that are normally abundant in the intestinal tracts of human and other warm-blooded animals and are used as indicators (being measured as the number of individuals found per millilitre of water) when testing the sanitary quality of water. Immunological Methods in Microbiology. Tatsuya Tominaga, Masaharu Ishii, in Methods in Microbiology, 2020. 11.3 Indicator bacteria. Coliform bacteria are defined as Gram-negative non-spore-forming bacilli, which degrade lactose into acids and gas within 48 h. A number of Enterobacteriaceae such as the genus Citrobacter, Enterobacter, Escherichia, and Klebsiella are included, in addition to the 12.2.2.1 Coliform Bacteria. Coliform bacteria are defined as rod-shaped Gram-negative nonspore forming and motile or nonmotile bacteria that can ferment lactose with the production of acid and gas when incubated at 35-37°C. They are a commonly used indicator of sanitary quality of foods and water. Coliform mastitis occurs when Gram-negative bacteria from the environment contaminate the opening of the papillary duct and ascend. Currently, the most common coliform bacteria in veterinary medicine are Escherichia coli, Enterobacter aerogenes, and Klebsiella pneumoniae. Coliform bacteria probably exert their damaging effect via endotoxin and Coliforme bakterier omfatter en lang række forskellige bakterier, som opfører sig ens. De findes naturligt i jord, overfladevand og forrådnede planter - men som udgangspunkt ikke i drikkevand (mængden kan typisk ikke påvises med den krævede metode og må derfor ikke kunne påvises).
