| Abstract |
|
The distribution of slide coagulase-negative staphylococci isolated from bovine mastitic milk samples was investigated mainly according to Kloos and Schleifer's classification scheme, and toxigenic and enzymatic characteristics of these strains were also examined. One-hundred-and-twenty-one strains of coagulase-negative staphylococci isolated were classified into 8 species. Of these species, Staphylococcus epidermidis, Staph. xylosus, Staph. haemolyticus and Staph. simulans were more frequently found in bovine mastitic milk samples, and toxin and enzyme production of these species were observed in relatively high frequency. Staph. hyicus subsp. hyicus was isolated from the 4 quarters with clinical mastitis included in this investigation. By the use of Baird-Parker and Pelzer's classification system, 44.6% and 18.2% of the strains could not be classified in any subgroup, respectively. |
