Crystal Violet Agar as a Differential Medium for Staphylococci.
In a previous paper Chapman, Berens, Peters and Curcio (1934) showed that staphylococci could be differentiated on the basis of their hemolysis and coagulase reactions. It was further shown that a critical interpretation of the hemolysis test depended upon an accurate knowledge of the pigment production of the strain. The existence of intermediate-colored strains or of dissociants showing wide ...
متن کاملClassification of staphylococci by penicillin lysis.
It has been recognized for some time that staphylococci may be divided into those which do and those which do not produce a penicillinase (Hobby & Dawson, 1944; Spink, Ferris & Vivino, 1944; Kirby, 1945a, b) . Also, staphylococci are often tested for their penicillin sensitivity (tolerance) and classified as ‘sensitive’ or ‘insensitive’. The literature contains a number of references to another...
متن کاملTellurite-glycine agar: a selective plating medium for the quantitative detection of coagulase-positive staphylococci.
The coagulae-positive staphylococci comprise a very homogeneous, readily identifiable species (Evans and Niven, 1950; Shaw et al., 1951) that includes all of the proven pathogenic and enterotoxin-producing strains of staphylococci. As a result of the clinical and public health significance of these organisms, a selective medium for their isolation and enumeration would have considerable value. ...
متن کاملGrowth of staphylococci on mercuric chloride agar.
Smith, P. B. (Communicable Disease Center, Atlanta, Ga.). Growth of staphylococci on mercuric chloride agar. J. Bacteriol. 84:1016-1019. 1962.-An attempt has been made to corroborate a report that "epidemic" strains of staphylococci are more resistant to mercuric salts than are "nonepidemic" strains. A comparison of mercury resistance with coagulase production and phage type or pattern of 493 s...
متن کاملPolymyxin-coagulase-mannitol-agar. I. A selective isolation medium for coagulase-positive Staphylococci.
A selective, differential plating medium was developed for the isolation and identification of coagulase-positive and mannitol-fermenting staphylococci. Coagulase produced by growing Staphylococcus aureus caused an opaque zone of fibrin to form around each colony. Several strains of S. aureus produced a visible coagulase reaction by 8 hr, and all strains gave a positive reaction before 12 hr. M...
