Abstract:
Three pigment production media were compared with CAMP and hippurate hydrolysis tests for the identification of beta-Streptococcus group B. A total of 129 clinical isolates of beta-Streptococcus group B and 287 beta-Streptococcus non group B were tested. The results show that sensitivities are: pigment medium, 99.2%, DMS medium, 95.6%, Columbia agar, 92.8%, CAMP test, 96.3%, hippurate hydrolysis test, 97.6%. As for specificities results show: CAMP test, 99.7%, the other tests, 100%; respectively. Pigment medium is a simple, convenient methodology.
