The Public Health Laboratory Diagnosis of Enteric Infections


A method for the isolation and identification of Shigella and Salmonella from fecal specimens has been described. For convenience in performance the procedure was set up under five main divisions; planting, screening, presumptive serology, biochemical confirmation and serological identification. The simple screening and presumptive serological tests adopted have been found to reduce to a minimum the number of organisms that require further biochemical and serological study for complete identification.
