CULTURE TECHNIQUES
Conventional approaches
to microbiological examination of specimens require that they be cultured to
assess the total numbers of specific groups of microorganisms or to determine
the presence or absence of particular named species. The majority of samples
taken for examination contain mixtures of different species, so simple plating
onto an agar surface may fail to detect an organism that is present at <2% of the total viable population. Various
enrichment culture techniques may therefore be deployed to detect trace numbers
of particular pathogens, prior to confirmatory identification.
