Procedure, Result and Limitation CAMP test was first identified by Christie, Atkins, and Munch-Peterson in 1944 and CAMP test is an acronym of three researchers. Hence, there is a large natural variation in CFU results from plate counts particularly if single replicate samples are used and single tests are conducted. Consequently, there is an uneven distribution of microbes even in well-mixed samples that create problems not only for test methods but sampling in order to get a meaningful result for the batch.
