FIG. 4. Close-up view of a positive CAMP test on Streptococcus agalactiae  (group B) when tested against Staphylococcus aureus. Note the arrow-shaped zone of enhanced hemolysis resulting in complete clearing of the blood agar plate. (Anne Hanson, University of Maine)
 
FIG. 5. Close-up view of a negative CAMP test on Streptococcus pyogenes (group A) when tested against Staphylococcus aureus. Note the absence of the arrow-shaped zone of enhanced hemolysis. (Anne Hanson, University of Maine)

FIG. 6. CAMP-positive Streptococcus agalactiae (group B) inoculated at right angles to the test organism Staphylococcus aureus. Note the arrow-shaped zones of enhanced hemolysis. (Matthew Pietraszewski, University of Maine)

FIG. 7. CAMP-negative Streptococcus pyogenes (group A) inoculated at right angles to the test organism Staphylococcus aureus. Note the absence of arrow-shaped zones of enhanced hemolysis. (Matthew Pietraszewski, University of Maine)
