title: Three-tube method for screening stool cultures for Salmonella and Shigella.
abstract: A three-tube method developed is described as a screening test for non-lactose-fermenting organisms isolated from stool cultures. To evaluate the method, 976 strains of gram-negative bacilli were tested. All strains of Salmonella and Shigella were correctly identified generically.
