A process for detecting the presence or absence of gram-positive bacteria in a biological sample. The biological sample can be obtained from any mammal and contains, at a minimum, cellular components. The sample is combined with an enzymatic lysing agent such as achromopeptidase, and lysed at room temperature. Ferric oxide is then added to the sample containing achromopeptidase. A magnetic field is applied to the sample and nucleic acids are extracted from the cellular components. Target nucleic acids, if present, are amplified using techniques such as Polymerase Chain Reaction (PCR) and then used to detect the presence or absence of gram-positive bacteria. Staphylococcus aureus and Streptococcus agalactiae are examples of target bacteria detected by the methods of the present invention. |
