Default Strep agalactiae - CAMP factor

I understand that CAMP factor is normally produced by Strep agalactiae and this factor enlarges the area of hemolysis of S. aureus.

What is the significance of this information from a clinical / diagnostic point of view? Does it mean I can use this cross reaction to confirm infection by either bacteria?

CAMP test is used in the diagnosis of S. agalactiae. You won't use it in the identification of S. aureus, because in the diagnostic algorithm, you do the catalase test first (after Gram stain -- obviously). Therefore, you only do the CAMP test if you suspect S. agalactiae.
