CAMP Test vs. Reverse CAMP Test: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on February 6, 2024
CAMP Test is a biochemical test for identifying bacteria producing the CAMP factor, typically Streptococcus agalactiae. Reverse CAMP Test identifies bacteria inhibiting the CAMP factor, often used to differentiate Staphylococcus species.

Key Differences

The CAMP test is a biochemical assay used to identify the presence of CAMP factor, an extracellular protein produced by certain bacteria like Streptococcus agalactiae. The reverse CAMP test, in contrast, is used to detect bacteria that inhibit the CAMP factor, mainly to differentiate between species of Staphylococcus.

In the CAMP test, a streak of bacteria suspected of producing the CAMP factor is placed perpendicular to a streak of Staphylococcus aureus on a blood agar plate. In the reverse CAMP test, the roles are reversed; the test organism is streaked alongside a line of a known CAMP factor producer.

The CAMP test results are interpreted by the formation of an enhanced hemolysis area where the two bacterial streaks meet, indicating a positive result. In the reverse CAMP test, inhibition of hemolysis or a diminished hemolysis zone indicates a positive result.

The CAMP test is primarily used in clinical microbiology to identify Group B Streptococcus, which is an important pathogen in neonatal infections. The reverse CAMP test is useful in identifying certain Staphylococcus species, which have clinical significance in nosocomial infections.

Both tests are simple, cost-effective, and require minimal specialized equipment, making them accessible in most microbiology laboratories. However, their specificity and sensitivity can vary, and they are often used in conjunction with other diagnostic methods.
