New Medium for Blood Cultures

¹ Diagnostic Service, Department of Microbiology, Columbia University College of Physicians & Surgeons, New York, New York 10032

ABSTRACT

A new medium suitable for blood cultures is described. It contains dextrose, cysteine, iron, and magnesium, in a tris(hydroxymethyl)aminomethane buffer, and a mixture of peptones derived from animal tissues, casein, and yeast. In comparison with Trypticase Soy Broth, the growth rate constants of Staphylococcus aureus, Streptococcus (Viridans group), enterococcus, and Escherichia coli were higher in this medium, and growth appeared earlier in a significant number of clinical blood cultures.
