Research on the Re Identification of Suspected Pseudomonas aeruginosa in Drinking Water
Pseudomonas aeruginosa is a conditional pathogenic bacterium that is not allowed to be detected in drinking water.This paper observed the colony morphology and confirmed biochemical reactions of 10 single colonies isolated from drinking water samples.Further identification was carried out using various methods such as HK-MID bacterial biochemical identification system,VITEK 2 fully automated microbial identification system,and 16S rRNA gene sequencing.The identification results indicate that some strains are not Pseudomonas aeruginosa,but rather opportunistic pathogens.From the perspective of food safety,these should not appear in drinking water or mineral water.In addition to exploring the accuracy and timeliness of testing methods that have been widely studied in previous studies,this paper also analyzes these strains,providing research basis and reference value for quality supervision and standard formulation by relevant management departments.
