Tryptic soy medium is feasible for the in situ preparation of standards containing small defined numbers of microbial cells.

Abstract:

:A standard material comprising a few viable cells of a microorganism is essential for rational validation of microbiological methods. We propose a method of a flow cytometric sorting of cells stained with 6-carboxyfluorescein diacetate. The feasibility of tryptic soy medium in this method is demonstrated with 5 strains.

  • Development of RNA aptamers for detection of Salmonella Enteritidis.

    abstract::We developed and evaluated RNA aptamers to analyze their potential for use in detecting Salmonella Enteritidis. The selected aptamer was observed to specifically bind to Salmonella Enteritidis without any cross-reactivity to other Salmonella serovars. Thus, this study suggests that aptamers specific to Salmonella Ente...
