When grown on brain heart agar plates. Staphylococcus capitis, S. warneri and S. xylosus produced a precipitation line with normal human serum in the double diffusion test. Eight other staphylococcal species did not produce this line. Of 20 strains of S. capitis , all produced the precipitation line, and the type strain of S. capitis produced the precipitation line against the sera from eight animal species. The precipitation is not caused by protein A and it is not an immune reaction because the serum component is in the albumin fraction of serum when fractionated on Sephadex G‐200.
