A new enrichment medium for salmonellae

Abstract

A new enrichment medium for the isolation of salmonella types from faeces is described. The inhibitory substances for coliform organisms and enterococci in this medium are magnesium chloride and sodium hydrogen selenite. The new medium was found in routine diagnostic work to be superior to the MuellerKauffmann medium in the isolation of Salmonella typhi and only a little inferior in the isolation of other salmonella types. When used in addition to the standard media the new medium increases the number of positive results. I am indebted to Dr Jadranka Zajc-Satler for the identification of the salmonella types isolated and to Mrs I. Mamilovi, Miss P. Ferbear, and Mrs D. Zavodnik for technical assistance. © 1964, Cambridge University Press. All rights reserved.
