[A simple biological method for the fast identification of antibiotics]

A method used to determine the quantitative and qualitative determination of antibiotics in blood, injury discharge, in human and animal urine as well as in foodstuffs (meat, milk and products made of them) is described. It is based on using obligate, thermophilic bacteria Bacillus stearothermophilus, strains KK BKM B-213OD and BKM B-718 with an optimum growth at 55-60 degrees C. Meso- and psychrophilic bacteria cannot grow at the above temperature, therefore, the studied non-sterile material does not need any preliminary thermal treatment prior to the indicator-strain, which is highly sensitive to all widely used antibiotics, is sown in the test-culture bacterial lawn.
