| Abstract |
The method provides a direct count of Aeromonas in water based on the development of yellow colonies on the surface of the membrane filter using a selective media for Aeromonas species. A water sample is filtered through 0.45 micrometer membrane filter. The filter is placed on ampicillin-dextrin agar and incubated at 35 C +/- 0.5 C for 22 to 26 hours. This medium uses 10-milligram/liter ampicillin to inhibit non-Aeromonas species, while allowing Aeromonas to grow. The medium uses dextrin as a fermentable carbohydrate, and bromothymol blue as an indicator of acidity produced by the fermentation of dextrin. Yellow presumptively identified colonies are counted and confirmed by testing for the presence of cytochrome c (oxidase test) and the ability to ferment trehalose. The membrane filtration procedure provides a direct count of culturable Aeromonas in water samples that is based on the bacterial growth on the surface of the membrane. |
