摘要: A method of detecting a ligase expressing micro-organism in a sample comprises steps of treating the sample under conditions that inhibit the activity of ATP-dependent ligase from mammalian cells but which do not inhibit the activity of the microbial ligases, contacting the sample or a portion of the sample with a nucleic acid molecule which acts as a substrate for ligase activity in the sample, incubating the thus contacted sample under conditions suitable for ligase activity; and specifically determining the presence and/or the amount of a ligated nucleic acid molecule resulting from the action of the ligase on the substrate nucleic acid molecule to indicate the presence of the ligase expressing micro-organism. The micro-organism may be a fungus or a bacterium or both. High pH conditions may be employed to inactivate mammalian ligases. Related kits are described.
