BACKGROUND & OBJECTIVES Loop-mediated isothermal amplification (LAMP) is an emerging nucleic acid based diag- nostic approach that is easily adaptable to the field settings with limited technical resources. This study was aimed to evaluate the LAMP assay for the detection and identification of Plasmodium falciparum and P. vivax infection in malaria suspected cases using genus and species-specif...

Genetically modified (GM) rice KMD1, TT51-1, and KF6 are three of the most well known transgenic Bt rice lines in China. A rapid and sensitive molecular assay for risk assessment of GM rice is needed. Polymerase chain reaction (PCR), currently the most common method for detecting genetically modified organisms, requires temperature cycling and relatively complex procedures. Here we developed a ...

OBJECTIVES To evaluate the performance of the eazyplex(®) SuperBug CRE system, a loop-mediated isothermal amplification (LAMP)-based system, for confirming the presence of carbapenemases in addition to CTX-M-type ESBLs in previously genotypically and/or phenotypically characterized clinical Enterobacteriaceae isolates recovered in two centres in Spain. METHODS A collection of 94 carbapenemase...

Foodborne disease is a major public health threat worldwide. Salmonellosis, an infectious disease caused by Salmonella spp., is one of the most common foodborne diseases. Isolation and identification of Salmonella by conventional bacterial culture or molecular-based methods are time consuming and usually take a few hours to days to complete. In response to the demand for rapid on line or on sit...

Here we report the design and evaluation of a loop-mediated isothermal amplification (LAMP) assay for detecting Acinetobacter baumannii DNA based on the 16S-23S rRNA intergenic spacer (ITS) sequence. The results showed that target DNA was amplified and visualized within 30min and with a detection limit 100-fold greater than PCR.

The northern root-knot nematode (Meloidogyne hapla) is a damaging nematode that has caused serious economic losses worldwide. In the present study, a sensitive, simple and rapid method was developed for detection of M. hapla in infested plant roots by combining a Flinders Technology Associates (FTA) card with loop-mediated isothermal amplification (LAMP). The specific primers of LAMP were desig...

We developed a one-pot label-free molecular beacon-mediated quadratic isothermal exponential amplification strategy (LFMB-QIEA) for simple, rapid and sensitive DNA methyltransferase (MTase) activity detection.

A numerical model based upon the "Stoner-Wohlfarth theory" has been developed to predict Isothermal Remanent Magnetisation (IRM) curves for a system of fine particles with uniaxial anisotropy. This paper reports the predictions of our model for the effects of easy axes alignment on the IRM curve. We have also investigated the effect of the standard deviation after the application of a non-satur...

The development of sensitive, rapid, and accurate diagnostic methods for vivax malaria is essential for the effective control of malaria in the Republic of Korea, where vivax malaria patients usually show low parasitemia. In this study, a TaqMan-based real-time polymerase chain reaction (PCR) method was established and compared with other PCR-based assays, including nested PCR, loop-mediated is...

A multiplex loop-mediated isothermal amplification (mLAMP) assay was developed for simultaneous detection of the stx1 and stx2 genes and applied for detection of shiga toxin-producing Escherichia coli (STEC) in cattle farm samples. Two target genes were distinguished based on Tm values of 85.03 ± 0.54°C for stx1 and 87.47 ± 0.35°C for stx2. The mLAMP assay was specific (100% inclusivity and exc...
