title: Presumptive identification of group B streptococci by rapid detection of CAMP factor and pigment production.
abstract: Modified rapid versions of CAMP and pigment tests were developed for the identification of group B streptococci using the supernatant and cell deposit of organisms grown for 4 hr in a modified Todd-Hewitt broth. All but one of 203 group B streptococci were reliably differentiated from 148 nongroup B strains.
