TLDR
Strains isolated from the skin and the upper respiratory tract of chickens and from bovine udders showed characteristics typical for Staphylococcus epidermidis biotype 2, but produced a heat-resistant nuclease (DNase) and reacted in the tube coagulase test.Abstract:
Strains isolated from the skin and the upper respiratory tract of chickens and from bovine udders showed characteristics typical for Staphylococcus epidermidis biotype 2, but produced a heat-resistant nuclease (DNase) and reacted in the tube coagulase test. The strains were physiologically, biochemically and serologically indistinguishable from Staphylococcus hyicus strains isolated from swine. However, in contrast to S. hyicus, they appeared to be devoid of pathogenicity when tested in colostrum deprived piglets. The poultry strains occur frequently as skin inhabitants.read more

Nonstarter Lactobacilli in Cheddar Cheese: A Review

TL;DR: Efforts to accelerate cheese ripening by increasing amounts of active peptidases have been only partially successful, and results depended on numbers, strain, type of cheese, and condition of manufacture.

Staphylococcus hyicus (Sompolinsky 1953) comb. nov. and Staphylococcus hyicus subsp. chromogenes subsp. nov.
TL;DR: A taxonomic analysis of 168 strains of this species isolated from swine with infectious epidermitis, from the skin and nares of healthy pigs and poultry, and from cows with mastitis found forty-eight strains which produced unpigmented colonies and a heat-stable nuclease were placed in the type subspecies S. hyicus subsp.

Slime production, DNase activity and antibiotic resistance of Staphylococcus aureus isolated from raw milk, pasteurised milk and ice cream samples
TL;DR: There was a high rate of resistance for all S. aureus isolates against penicillin G, methicillin and bacitracin, and few numbers of the strains were resistant to erythromycin.

A classification of micrococci and staphylococci based on physiological and biochemical tests.
TL;DR: Gram-positive and catalase-positive cocci were isolated from bacon, pig and human skin and dust, and their morphology, physiology and biochemical characters examined and the genera Staphylococcus, Micrococcus and Sarcina were recognized.

TL;DR: Three, convenient agar-diffusion methods have been developed that enable detection of the nuclease of Staphylococcus aureus at concentrations as low as 0.005 mug/ml in agar and broth cultures.

The classification of staphylococci and micrococci from world-wide sources.
TL;DR: It appears that the Gram-positive and catalase-positive cocci are best separated into the genus Staphylococcus and the genus Micrococcus on the ability of members of Staphyllococcus to grow and produce acid from glucose anaerobically.
