NOVELTY - Horizontal procedure for enrichment and detection of pathogen bacteria in a sample including Salmonella, Listeria etc., from faeces, food, animal feed and other products that can be consumed by or get in contact with human, domestic animals, involves enriching pathogen target-bacteria in a pre-enrichment buffer and transferring a transfer volume (partial volume of pre-enrichment buffer) to a target-bacteria selective enrichment buffer.    USE - (M1) for enrichment and detection of pathogen bacteria in a sample including Salmonella, Listeria, Escherichia coli, Campylobacter, Yersinia etc., from faeces, food, animal feed and other products which can be consumed by or get in contact with human, domestic animals or pets, where other products includes but is not restricted to feather, dust, down sewage and HACCP-samples. (M1) is useful for the determination of the presence of a single pathogen bacterium in an investigated product. The pathogen is preferably the bacterium salmonella (claimed).    ADVANTAGE - (M1) is a horizontal fast-method that enables efficient, rapid and reliable detection of the presence of pathogenic bacteria in food, feed, domestic animals, faeces, sewage etc.    DETAILED DESCRIPTION - Horizontal procedure (M1) for enrichment and detection of pathogen bacteria in a sample including Salmonella, Listeria, Escherichia coli, Campylobacter, Yersinia etc., from faeces, food, animal feed and other products which can be consumed by or get in contact with human, domestic animals or pets, where other products includes but is not restricted to feather, dust, down sewage and HACCP-samples, involves enriching pathogen target-bacteria in a pre-enrichment buffer and transferring a transfer volume (a partial volume of the pre-enrichment buffer) to a target-bacteria selective enrichment buffer, which selective enrichment buffer as a minimum contains an agent which is not tolerated or is tolerated poorly by non-target bacteria (other bacteria) or other selective pressure on non-target bacteria e.g. pH and osmosis, where the pre-enrichment medium is pre-warmed to above room temperature, preferably above 28degreesC; the transfer volume from the pre-enrichment to the selective enrichment is carried out after less than 14 hours; and the transfer volume is preferably at least 1 mL respectively at least 1/200 of the selective growth medium.
