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. |
