Evaluation of the Redesigned Enterotube—a System for the Identification of Enterobacteriaceae

The redesigned Enterotube has been evaluated with 414 unknownEnterobacteriaceae cultures from the stock culture collection of the Center for Disease Control. When the Enterotube was used as recommended by the manufacturer, an average of 96.4% of these cultures were correctly identified. Only two groups (Salmonella andEdwardsiella ) were identified with less than 90% accuracy (89.2 and 87.5%, respectively). The Enterotube now provides a convenient, rapid, and accurate test system for the identification of typically reacting enteric bacteria.
