Abstract
A swab comprising gelatine or collagen has been found to have a remarkably high recovery of microorganisms. Furthermore, the samples, such as microorganisms, spores, nucleotides and other biologically or biochemically relevant compounds can be fully recovered from the collagen-or gelatine-comprising swab. The invention thus provides a method and swab which has a high recovery of a target from a sample and furthermore a second high recovery when transferring from the swab to a medium for analysis.
