FIG. 1. CAMP-positive Listeria monocytogenes inoculated at right angles to b-hemolytic Staphylococcus aureus. Note the arrow-shaped zone of weak enhanced hemolysis indicating a positive CAMP test. (Anne Hanson, University of Maine)
FIG. 2. CAMP-positive Listeria monocytogenes inoculated at right angles to b-hemolytic Staphylococcus aureus. Note the arrow-shaped zone of weak enhanced hemolysis indicating a positive CAMP test. Gloves are worn when working with L. monocytogenes. (Anne Hanson, University of Maine)
FIG. 3. Close-up view of CAMP-positive Listeria monocytogenes inoculated at right angles to b-hemolytic Staphylococcus aureus. Note the arrow-shaped zone of weak enhanced hemolysis indicating a positive CAMP test. (Anne Hanson, University of Maine)

FIG. 3. Reverse CAMP test showing both positive and negative results. Streptococcus agalactiae (group B) is streaked down the center of the plate the test organisms, Clostridium sp., are streaked at right angles to the Streptococcus agalactiae (group B). The positive reverse CAMP reaction of Clostridium perfringens is shown by the “bow-tie" zone of hemolysis. The negative reverse CAMP reaction of Clostridium septicum shows no hemolysis. (Anne Hanson, University of Maine)
FIG. 4. Close-up view of the positive reverse CAMP reaction demonstrated by Clostridium perfringens when tested against group B Streptococcus. Note the bow-tie zone of enhanced hemolysis pointing towards the Streptococcus agalactiae (group B). (Anne Hanson, University of Maine)
