| 摘要 |
The invention relates to a positive control nucleic acid molecule comprising first and second primer hybridization sequences derived from a first microorganism which flank an internal nucleic acid sequence that is not naturally present in the first microorganism. The invention further relates to a positive process control microorganism comprising said positive control nucleic acid molecule, to a receptacle comprising said positive control microorganism, and to methods for determining whether a first microorganism is present or absent in a test sample, comprising contacting the test sample with the positive process control microorganism and generating amplification products using first and second primers that hybridize to the first and second primer hybridization sequences. |
