ABSTRACT
A rapid and sensitive method of loop-mediated isothermal amplification(LAMP) was established to detect Pseudomonas aeruginosa(P.aeruginosa).Three pairs of LAMP primers(inner,outer and ring primers) were designed according to the gbca gene of P.aeruginosa.Since adding hydroxy naphthol blue(HNB) to the reaction system, a positive reaction was indicated by a colorchange before and after the reaction,and was verified by agarose gellectrophoresis.Both LAMP and PCR were applied to detect clinical specimens, the sensitivity and specificity of the detection method were evaluated,and were compared with those of conventional PCR.A LAMP method for detecting P.aeruginosa was successfully established.The LAMP method showed specificity for P.aeruginosa without other bacteria amplification.The established LAMP method in this study enables rapid,sensitive and specific detection of P.aeruginosa,and can be applied for grass roots and small scale laboratories as well as field surveillance.
