Comparison of Desoxyribonuclease Activity to Some Other Criteria of <i>Staphylococcus </i>Pathogenicity

Extracellular Nuclease Activity of Fish Spoilage Bacteria, Fish Pathogens, and Related Species

“…Levin (6) previously reported the complete absence of Proteus from haddock with Pseudomonas putrefaciens occurring as the sole H2S-forming spoilage organism. The determination of extracellular deoxyribonuclease formation has been shown to be useful in confirming staphylococcal pathogenicity (8) and for aiding in the differentiation of members of the family Enterobacteriaceae (8,10,12). This report documents pronounced polynucleotide degradation by extracellular deoxyribonuclease and ribonuclease produced during the growth of fish spoilage and related organisms and the taxonomic significance of these enzymes.…”
