Streptococcus agalactiae, CAMP test on blood agar. Cultivation 24 hours, aerobic atmosphere enriched with 5% CO2, 37°C.
The CAMP test is a test to identify Group B beta-hemolytic streptococci based on their formation of a substance (CAMP factor) that enlarges the area of hemolysis formed by ß-hemolysin from Staphylococcus aureus. It is an acronym for "Christie Atkins Munch-Petersen", for the three researchers who discovered the phenomenon.
