    Usefulness of fatty acid analysis for identification of nutritionally variant streptococci

  • Original language description

    An overlap in physiologic characteristics between nutritionally variant streptococci (NVS) and other gram-positive catalase-negative cocci is known. Two years of study yielded 9 isolates of NVS from blood cultures. It is possible to confirm preliminary phenotypical identification as NVS by fatty acid analysis based on whole cell fatty acid methyl esters (MIS Sherlock, MIDI, Inc., USA). The fatty acid composition of phenotypically similar Streptococcus spp. differs significantly from all tested NVS. Fatty acid analysis could be an useful tool for the discrimination of G. elegans from G. adiacens and A. defectiva and this method could help to distinguish G. morbillorum from NVS.

    Využití analýzy mastných kyselin pro identifikaci nutričně deficitních streptokoků

  • Czech description

    Diferenciace nutričně deficitních streptokoků (NVS) od ostatních grampozitivních kataláza-negativních koků pouze na základě fenotypu je nedostačující. Testováno bylo 9 kmenů NVS izolovaných z hemokultur. Identifikaci jako NVS je možné potvrdit analýzou methylesterů mastných kyselin (MIS Sherlock, MIDI, Inc., USA). Fenotypově podobné izoláty Streptococcus spp se signifikantně lišily svým složením mastných kyselin. Analýzu mastných kyselin lze použít k diferenciaci G. elegans od G. adiacens a A. defectivaa uvedená metoda může pomoci odlišit G. morbillorum od izolátů NVS.
