T/SDAQI 007-2021 The rapid qualitative detection of Pseudomonas aeruginosa in water production using real-time PCR method
Basic Information
Scope
Scope: This document is applicable to the rapid qualitative detection of Pseudomonas aeruginosa in production water; Main technical content: After the sample is filtered by a vacuum filtration device, the filtered membrane is placed in a selective medium for cultivation. The cultured bacterial solution is collected for DNA extraction. Using DNA as the template, the bacterial 16S rDNA gene sequence is used as an internal reference, and primers and probes that are relatively conserved and highly specific to the exotoxin A (eta) gene in Pseudomonas aeruginosa are used for real-time fluorescence PCR amplification of the target. Based on the Ct value, it is determined whether the sample contains Pseudomonas aeruginosa. Among them, the detection of the internal reference reaction can monitor whether the reaction is normal and prevent false negative results.
