[Enterobacteria erroneously identified as Salmonella in human faeces (author's transl)].

To differentiate Citrobacter freundii, Enterobacter hafniae, Proteus mirabilis and Alteromonas putrefaciens from Salmonella strains isolated in faeces, the author recommends the use of "Hajna-Kligler" medium, "Nitrate-Motility-Mannitol" medium, "Urease-Indole-Trytophane desaminase" medium and glycerol peptonated water. The lysis of Salmonella and E. hafniae strains by specific phages (Felix and Callow O: 1 Salmonella phage; Guinee and Valkenburg Hafnia phage) is emphasized.
