Abstract
Method for isolating microorganism from a sample likely contaminated by microorganism, including: (a) device for isolating microorganisms including a bottom waterproof layer, a nutritional layer, which is placed on the bottom layer and includes a dehydrated culture medium, an isolation layer which is pervious to elements included in the nutritional layer and is capable of retaining the bacteria on the surface and covering all or part of the nutritional layer, and a top protective layer; (b) depositing a volume of the sample on the isolation layer; (c) isolating the microorganisms by impoverishing or layering the sample using an isolating device; (d) incubating the device for an amount of time at a temperature to enable growth of microorganisms, method including at least one step of rehydrating the culture medium using a volume of liquid before or with step b) and/or c) and/or d), before or simultaneously with step b) and/or c).
