+          The fluorescence value of pUC57-cagA increased slowly and then increased linearly with increasing DNA
+          concentration. The fluorescence value of pUC57-inVA increased linearly with increasing DNA concentration.
+          However, the fluorescence value of pUC57-ipaH and Puc57-16S increased first, and then stabilized with
+          increasing DNA concentration.The model was used to predict the relationship between the fluorescence value and
+          the DNA content of pathogenic bacteria in the sample.It has important biological significance for studying
+          pathogenic bacteria.
