RESUMO
Coliforms, primarily Citrobacter freundii, gave negative verification results in the total-coliform membrane filtration test. The organisms produced gas from lactose in brilliant green bile broth but not in lauryl tryptose broth. The discrepancy was related to the peptone sources used in the media.
