A Comparison of Methods and the Validity of Deoxyribonuclease Tests for the Characterization of Staphylococci Isolated from Animals

Abstract
Strains isolated from pigeons belonging to the coagulase‐positive species Staphylococcus intermedius, coagulase‐negative Staph. hyicus subsp. chromogenes strains from cattle and pigs, and Staph. aureus strains from poultry, gave weakly positive reactions in DNase plate culture tests and heat‐resistant DNase tests. Staph. aureus and Staph. intermedius strains from other sources and coagulase‐negative and coagulase‐positive Staph. hyicus subsp. hyicus strains reacted strongly in these tests. A standardized plate culture test procedure is proposed and the use of DNase tests in the identification of staphylococci isolated from animals is discussed.
