The amplification patterns of LAMP reactions were highlydependent on the bacterial concentration in the solution(Fig. 3). For instance, LAMP assays showed amplificationaround × 10−1 cfu/ml from the bacterial suspension templates(Fig. 3), but the relative fluorescence curves were irregularbelow × 103 cfu/ml concentration. The efficiency of theLAMP assay was further improved by using the bacterialDNA as a template, since we were able to detect the minimum×10−2 cfu/ml serial dilution of DNA from E2002A strain.However, the latter approach will require isolation or regrowingof isolated bacteria from the infected samples andDNA extraction from them.
