Abstract (en)
[origin: WO0023792A1] A method for concentrating a particular microorganism or microorganisms of interest in a sample is provided and effected by contacting the sample with a matrix to which is bound an affinity receptor specific for the particular microorganism or microorganisms, the affinity receptor and the matrix being selected so as to allow capture of the microorganism or microorganisms to the matrix via the affinity receptor when present in the sample at a concentration of ultra low levels, thereby obviating the need for a prolonged pre-enrichment step, and in some cases obviating altogether the need for a pre-enrichment step, of the microorganism or microorganisms in the sample.
