Rapid and sensitive detection of human African trypanosomiasis by loop-mediated isothermal amplification combined with a lateral-flow dipstick.

A combined loop-mediated isothermal amplification lateral flow dipstick (LAMP-LFD) format was evaluated in the detection of human infective trypanosome DNA from clinical samples. The LAMP-LFD showed analytical sensitivity equivalent to 0.01 tryps/mL, levels that were identical to using gel electrophoresis and SYBR Green I dye.

Loop-mediated isothermal amplification (LAMP) method for rapid detection of Trypanosoma brucei rhodesiense.

Loop-mediated isothermal amplification (LAMP) of DNA is a novel technique that rapidly amplifies target DNA under isothermal conditions. In the present study, a LAMP test was designed from the serum resistance-associated (SRA) gene of Trypanosoma brucei rhodesiense, the cause of the acute form of African sleeping sickness, and used to detect parasite DNA from processed and heat-treated infected blood samples. The SRA gene is specific to T.
