Evaluation of Salmonella and Shigella identification with the MS2-BID automatic system.
The precision of the Abbott MS-2 system was evaluated for the rapid identification of Salmonella and Shigella strains in 5 hours. The results of 113 strains of Salmonella and 52 strains of Shigella studied showed a total agreement of 68% and 90% respectively with the API 20E method and with sero-agglutination taken as reference. But in 12.40% and 2% of the cases the Salmonella and Shigella strains were not recognised and no warning message was given by the automate. Moreover, during the daily utilisation of the apparatus, the 21 strains labelled Shigella and Salmonella were later shown to belong to other genera. The MS-2 BID system is therefore of limited interest in medical and in food microbiology.
