  1. Random amplification of polymorphic DNA (RAPD), pulsed-field gel electrophoresis (PFGE) and phage-typing in the analysis of a hospital outbreak of Salmonella Enteritidis.

    Article - En anglais

    Isolates of Salmonella Enteritidis from 81 patients from Herlev Hospital or from Copenhagen County were analysed by random amplification of polymorphic DNA (RAPD), pulsed-field gel electrophoresis (PFGE) and phage-typing.

    Fourteen polymorphic markers from five decamer primers unambiguously placed all isolates into six RAPD groups : 65 isolates of phage-type 6 (PFGE type I) were resolved into three RAPD groups constituting 86,12, and 2%, respectively.

    A fourth RAPD group of 10 isolates was coincident with phage type 8 (PFGE type II) and two isolates, one phage-type 1, the other phage-type 4 (both PFGE type I) formed the fifth group.

    The sixth group of four isolates was not phage typeable and was PFGE type III.

    Forty outbreak-related isolates of phage-type 6 were resolved into three strains.

    No diversity of phage-type 6 was found among isolates unrelated to the outbreak.

    It is concluded that RAPD is useful as a tool in investigations of microbial outbreaks in its own right, or to supplement phage-typing and PFGE of Salmonella Enteritidis.
