title: Modified Spot CAMP Test: A rapid, inexpensive and accurate method for identification of group B streptococci.
abstract: A rapid modified spot CAMP test using 183 clinical isolates of beta haemolytic streptococci was compared with the standard CAMP test described by Christie et al. The scheme of biochemical identification and serological confirmation was taken as reference method. The sensitivity of both tests was 100%, and the specificity of the rapid and standard tests was 96.8% and 88.9% respectively. The modified spot CAMP test is a rapid, inexpensive and accurate method for the identification of group B streptococci, and is more specific than the standard CAMP test.
