[Identification of Staphylococcus aureus by the sero-inhibition of nuclease in blood culture broths].

Identification of Staphylococcus aureus in blood cultures by sero-inhibition nuclease test is described in this paper. No positive results were found in 392 Staphylococcus other than Staphylococcus aureus bacteremia. Only 0,8% Staphylococcus aureus bacteremia could not be detected. This sero-inhibition nuclease test provides a rapid, less than 3 hours, easy to perform, reliable method to identify Staphylococcus aureus in blood cultures. Results are obtained 24 hours earlier than the conventional methods.
