Development and evaluation of a rapid on-site water pathogen detection system for water quality monitoring
2019
Timely response to outbreak of water-borne diseases caused by bacteria requires efficient monitoring and rapid detection strategies. Herein, we report a rapid DNA-based on-site detection system for specific detection of Pseudomonas aeruginosa. To evaluate the test performance of our method against spiked water samples, parallel tests based on real-time PCR and standard culture methods were concurrently performed. Test sensitivities of between 96.7% and 92.3% were obtained, based on the calculation obtained from qPCR and culture test, respectively, with a corresponding level of specificity of 92.9% and 83.3%. Time-to-result is around 45 min, with a detection limit of 1 CFU/100 mL. Here, a fully-deployable detection method where bacteria of-interest can be detected rapidly with high accuracy was described. This test method can be modified to detect other bacteria of-interest and can also be used in different applications. The test results can be obtained on-site and can therefore be particularly useful in public facilities health surveillance, where regulators can quickly determine if a site is safe or if other emergency response measures are required.
