A simple method for isolating DNA from enterococci has been developed. This method allows one to extract DNA of good quality in optimal amounts irrespective of the method used for obtaining the culture and the duration of its incubation. Mobile enterococci are sharply differentiated into 3 groups in accordance with their nucleotide composition, the content of GC pairs in DNA being 31.6% in group 1, 35.8-38.0% in group 2, and 40.6-41.5% in group 3.
