The results obtained with the procedure always coincided with those from the standard techniques from the clinical laboratory. The concentration where the check details presence

of the background of DNA fragments was observed coincided with that where nucleoids were released, in gram-negative strains. Nevertheless, in spite of releasing of nucleoids, the background of DNA fragments was very scarce or undetectable in susceptible gram-positive strains at the doses employed (Table 1 Figure 9).
