CAMP test

The CAMP test is a test to identify Group B β- based on their formation of a substance (CAMP factor) that enlarges the area of hemolysis formed by β-hemolysin from Staphylococcus aureus. It is frequently used to identify Group B Strep (.

Although usually used to identify group "B", there is some evidence that the CAMP factor gene is present in several groups of streptococci, including group "A".

A similar factor has been identified in Bartonella henselae.

It can be used to identify . Though not strongly beta-hemolytic on its own, it presents with a wedge-shape in the presence of Staphylococcus aureus.

CAMP is an acronym for "Christie–Atkins–Munch-Petersen", for the three researchers who discovered the phenomenon.

It is often incorrectly reported as the product of four people (counting Munch-Petersen as two people). The true relationship (three people) is the reason for two en dashes and then one hyphen in "Christie–Atkins–Munch-Petersen".

The name has no relationship to cyclic adenosine monophosphate (cAMP).
