title: [Comparative studies with the rapid KCN-test for Enterobacteriaceae according to Cahan, Sechter and Ohad (author's transl)].
abstract: 581 strains of Enterobacteriaceae (184 of Salmonella, 100 of Shigella, 31 of Citrobacter freundii, 61 of Escherichia coli, 40 of Klebsiella, 165 of Proteus) were investigated in comparison with the KCN-test according to Møller and with the rapid KCN-test according to Cahan, Sechter and Ohad. There was found that the results obtained with both methods were identical to 99 percent. In both tests there could be observed that inexplicable differences occur only in two strains of Proteus mirabilis. The rapid KCN-test can be recommended because of the good durability of the basic medium and of the solutions of the reagents, because of the short testing time (3 h), of the very good correspondence of the results and of the possibility of a well defined reading.
