Article Type: Full Length Research Article Polymerase chain reaction (PCR) and loop mediated isothermal amplification (LAMP) represent a major advance in diagnostic methods in terms of speed and sensitivity. However, standard methods for sample preparation prior to PCR and LAMP are laborious and time consuming. Three template preparation methods (crude template, boiling, and commercial DNA extr...

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...

conclusions results of the current study confirmed that molecular methods such as pcr and lamp were much more sensitive, rapid, and specific than culturing to identify non-culturable coccoid forms of h. pylori in water. results ten copies of targeted dna were required for pcr detection whereas only five copies gave a positive reaction by lamp assay, with 100% specificity. of the 10 isolates ino...

We have evaluated a diagnostic system based on the loop-mediated isothermal amplification (LAMP) assay for the rapid, simple, and sensitive detection of Newcastle disease virus (NDV) directly from culture isolates as well as clinical samples. By using one set of specific primers targeting the fusion protein gene, the LAMP assay rapidly amplified the target gene within 2 h, requiring only a regu...

A loop-mediated isothermal amplification (LAMP) assay allows rapid diagnosis of Toxoplasma gondii infection. In the present study, the LAMP assay was evaluated using blood from both naturally and experimentally infected pigs. The sensitivity of the LAMP assay was compared with that of Q-PCR. Both assays detected T. gondii in the blood of experimentally infected pigs, with 100% agreement. In inf...

Melioidosis is a severe infection caused by Burkholderia pseudomallei. The timely implementation of effective antimicrobial treatment requires rapid diagnosis. Loop-mediated isothermal amplification (LAMP) targeting the TTS1 gene cluster was developed for the detection of B. pseudomallei. LAMP was sensitive and specific for the laboratory detection of this organism. The lower limit of detection...

Loop-mediated isothermal amplification (LAMP), a rapid nucleic acid amplification method, was developed for the clinical diagnosis of toxoplasmosis. Three LAMP assays based on the SAG1, SAG2, and B1 genes of Toxoplasma gondii were developed. The sensitivities and specificities of the LAMP assays were evaluated by comparison with the results of conventional nested PCR. The LAMP assays were highl...

BACKGROUND Helicobacter pylori, causing the most common chronic bacterial infection, exist in two forms; bacilli and coccoid. The coccoid form is identified as viable but non-culturable bacteria. OBJECTIVES The current study aimed to conduct culture, polymerase chain reaction (PCR), and loop-mediated isothermal amplification (LAMP) tests to identify coccoid forms of H. pylori. MATERIALS AND...

BACKGROUND New field applicable diagnostic tools are needed for highly sensitive detection of residual malaria infections in pre-elimination settings. Field performance of a high throughput DNA extraction system for loop mediated isothermal amplification (HTP-LAMP) was therefore evaluated for detecting malaria parasites among asymptomatic individuals in Zanzibar. METHODS HTP-LAMP performance ...

Bovine viral diarrhea virus (BVDV) is a pathogen that infects cattle, and is globally important. It causes substantial financial losses to the livestock industry. In the current study, a one-step reverse transcriptase-loop-mediated isothermal amplification (RT-LAMP) assay was set up for rapid and efficient detection of BVDV. For this purpose, four primers were designed to recognize six distinct...
