Most isolates were identified as Staphylococcus caprae (N = 91) or S. xylosus (N = 36), but members of at least nine other species were present. Overall, some 57% of isolates produced toxins with phenotypic properties of ?-hemolysin, and 75% produced toxins resembling S. aureus ? and/or ?-hemolysins. Thermostable desoxyribonuclease (TNAse) was secreted by 29% of isolates and thermolabile DNAse by 66%. Slime was produced by 42% of our cultures, and, although none of them showed activity to insoluble elastase, over 70% lysed the soluble substrate. No clinical consequences were observed to correlate with exoprotein production, which proved to be inconstant within individual CNS species.  aBiosynthesis  aChemistry  aGoat diseases  aGoats  aMastitis  aMicrobiology  aPathogenicity  aRibonucleases  aStaphylococcus  aCaprino  aEtiologia  aPatogenicidade  aMastite1 aGREENLAND, T.1 aRICHARD, Y.  tVeterinary Microbiologygv.59, n.2-3, p.139-145, 1998.
