Abstract

Staphylococci isolated from different infections in dogs have been investigated for production of coagulase, deoxyribonuclease (DNase) and heat-stable DNase. Alll coagulase-positive strains (220) also produced DNase and heat-stable nuclease. However, 4 out of 15 coagulase-negative strains were also positive in both the DNase and the heat-stable DNase tests. Several tests for DNase and heat-stable DNase were evaluated. No strains were DNase-positive, heat-stable DNase-negative, or vice-versa.
