Commercial Betalysin CAMP Test

Commercial Betalysin CAMP Test
This picture shows a variation of the CAMP test. We have placed a disk at the top of this plate instead of the Staphylococcus streak. The disk contains the beta-lysin that is normally produced by the Staphylococcus. Since the disk is round, the shape of the increased hemolysis caused by the CAMP factor is different. These disks are available from several sources. Similar to the previous agar plates these tests were set up by: inoculating the plates, placing the disks in place, and incubating the plates overnight in an ambient atmosphere at 35oC.
