Use of Multiplex PCR and PCR Restriction Enzyme Analysis for Detection and Exploration of the Variability in the Free-Living Amoeba Naegleria in the Environment

摘要

A multiplex PCR was developed to simultaneously detect Naegleria fowleri and other Naegleria species in the environment. Multiplex PCR was also capable of identifying N. fowleri isolates with internal transcribed spacers of different sizes. In addition, restriction fragment length polymorphism analysis of the PCR product distinguished the main thermophilic Naegleria species from the sampling sites.
