 note = {application/pdf, The ability for staphylococci to coagulate plasma is generally accepted as a marker of pathogenic strains, and it is also one of the major criteria employed to differentiate S. aureus from S. epidermidis. However, the other properties which are correlated in varying degrees with coagulase production, such as DNase production, phosphatase production or tellurite reduction, are recently being employed by the diagnostic laboratory for the routine identification of a clinical isolate. The present study was designed to determine the possible correlation between coagulase production and the other biochemical properties of staphylococci isolated from bovine mastitis. The material used consisted of 122 coagulase-positive strains and 193 coagulase-negative ones. The results obtained are summarized as follows: 1) On sheep-blood agar every strain of coagulase-positive staphylococci was hemolytic and the great majority of those strains showed β or αβ hemolysis, whereas many strains of coagulase-negative staphylococci showed δ hemolysis or were non-hemolytic with the exception of 23 per cent of the strains which showed α hemolysis in appearance. 2) On the examination of DNase production, phosphatase production and tellurite reduction, it was found that all of the coagulase-positive strains showed positive results and that 16, 45 and 56 per cent of the coagulase-negative strains similarly showed positive results on each examination respectively. 3) The other biochemical properties except those described above did not correlate with the coagulase production. 4) The results of the present study indicate that the hemolysis on sheep-blood or cattle-blood agar has the advantage over the other biochemical reaction for isolation and identification of coagulase-positive staphylococci isolated from bovine mastitis and that the DNase production should be secondly ranked., Bulletin of the University of Osaka Prefecture.
