    Abstract

    Deoxyribonuclease (DNase) produced by Serratia marcescens is a characteristic feature which is useful in distinguishing this organism from closely related members of the Enterobacteriaceae. In an assessment of three methods of performing the DNase test as a screening procedure for Serratia marcescens, the conclusion was reached that the standard test was most suitable for use in the clinical bacteriology laboratory.
