Migratory water birds are a natural reservoir for influenza A viruses. Viruses replicate in the intestines of ducks and are shed with the fecal materials. Virus isolation from collected fecal materials, therefore, is an integral part of the surveillance of avian influenza in water birds. In the present study, reverse transcription loop-mediated isothermal amplification (RT-LAMP) was assessed fo...

Ralstonia solanacearum is a pathogenic bacterium that causes wilt in over 200 plant species. Here we report a rapid and sensitive detection of R. solanacearum using an isothermal method for copying DNA known as loop-mediated amplification (LAMP). A set of four primers was designed to replicate the gene coding for the flagellar subunit, fliC, and conditions for detection were optimized to comple...

BACKGROUND Aberrant DNA methylation of gene promoters and the associated silencing of tumor suppressor genes are recognized as mechanisms contributing to tumor development. Therefore, detection of promoter hypermethylation is becoming important for diagnosis, prognosis, and aiding the design of cancer therapies. We describe a novel isothermal method for the detection of DNA hypermethylation. ...

The cry2Ab and cry3A genes are two of the most important insect-resistant exogenous genes and had been widely used in genetically-modified crops. To develop more effective alternatives for the quick identification of genetically-modified organisms (GMOs) containing these genes, a rapid and visual loop-mediated isothermal amplification (LAMP) method to detect the cry2Ab and cry3A genes is descri...

Different immunoassay-based methods have been devised to detect protein targets. These methods have some challenges that make them inefficient for assaying ultra-low-amounted proteins. ELISA, iPCR, iRCA, and iNASBA are the common immunoassay-based methods of protein detection, each of which has specific and common technical challenges making it necessary to introduce a novel method in order to ...

AIMS To design and validate a colorimetric loop-mediated isothermal amplification assay for rapid detection of Phytophthora infestans DNA. METHODS AND RESULTS Two sets of loop-mediated isothermal amplification (LAMP) primers were designed and evaluated for their sensitivity and specificity for P. infestans. ITSII primers targeted a portion of the internal transcribed spacer region of ribosoma...

Loop-mediated isothermal amplification (LAMP) constitutes a potentially valuable diagnostic tool for rapid diagnosis of contagious diseases. In this study, we developed a novel LAMP method (seM-LAMP) to detect the seM gene of Streptococcus equi subsp. equi (S. equi), the causative agent of strangles in equids. The seM-LAMP successfully amplified the target sequence of the seM gene at 63°C withi...

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...

This study reports the development of a loop-mediated isothermal amplification procedure (LAMP) for polymerase chain reaction (PCR)-based detection of 'Candidatus Liberibacter solanacearum', the bacterial causal agent of potato zebra chip (ZC) disease. The 16S rDNA gene of 'Ca. Liberibacter solanacearum' was used to design a set of six primers for LAMP PCR detection of the bacterial pathogen in...
