Development of loop-mediated isothermal amplification assay for detection of human coronavirus-NL63.

ABSTRACT: Human coronavirus NL63 was identified in 2004 in the Netherlands. Due to the high prevalence and world-wide distribution of this pathogen, it is essential to develop a sensitive and specific detection assay suitable for use in a routine diagnostic laboratory. Techniques based on PCR or real-time PCR are laborious and expensive. Detailed analysis of the HCoV-NL63 genome permitted the identification of a conserved nucleic acid sequential motif, which was sufficient for the design of a loop-mediated isothermal amplification (LAMP) assay. Evaluation of the method showed that the test is specific to HCoV-NL63 and that it does not cross-react with other respiratory viruses. The detection limit was found to be 1 copy of RNA template per reaction in cell culture supernatants and clinical specimens.

Development of loop-mediated isothermal amplification assay for detection of Entamoeba histolytica.

Project description:A novel one-step, closed-tube, loop-mediated isothermal amplification (LAMP) assay for detecting Entamoeba histolytica, one of the leading causes of morbidity in developing countries, was developed. The sensitivity of the LAMP assay is 1 parasite per reaction. A total of 130 clinical samples were analyzed, and the results compared with those of conventional nested PCR to validate the practicability of this assay. No DNA was amplified from other diarrheal pathogens, such as other Entamoeba species, bacteria, and viruses. These results indicate that LAMP is a rapid, simple, and valuable diagnostic tool for epidemiological studies of amebiasis.

Development of Colorimetric Reverse Transcription Loop-Mediated Isothermal Amplification Assay for Detecting Feline Coronavirus.

Project description:Feline infectious peritonitis (FIP) is a worldwide fatal disease caused by a mutant feline coronavirus (FCoV). Simple and efficient molecular detection methods are needed. Here, sensitive, specific, rapid, and reliable colorimetric reverse transcription loop-mediated isothermal amplification (RT-LAMP) was developed to detect the ORF1a/1b gene of FCoV from cats with suspected FIP using neutral red as an indicator. Novel LAMP primers were specifically designed based on the gene of interest. The isothermal assay could visually detect FCoV at 58 °C for 50 min. The RT-LAMP assay was highly specific and had no cross-reactivity with other related feline viruses. The detection limit of FCoV detection by RT-LAMP was 20 fg/µL. A blind clinical test (n = 81) of the developed RT-LAMP procedure was in good agreement with the conventional PCR method. In the light of its performance specificity, sensitivity, and easy visualization, this neutral-red-based RT-LAMP approach would be a fruitful alternative molecular diagnostic tool for veterinary inspection of FCoV when combined with nucleotide sequencing or specific PCR to affirm the highly virulent FIP-associated FCoV.

Development of a loop-mediated isothermal amplification assay for rapid detection of capripoxviruses.

Project description:Sheep pox (SP), goat pox (GP), and lumpy skin disease (LSD), caused by capripoxviruses (CaPVs), are economically important diseases of sheep, goats, and cattle, respectively. Here, we report the development of a loop-mediated isothermal amplification (LAMP) assay for rapid detection of CaPVs. LAMP primers were designed to target a conserved gene encoding the poly(A) polymerase small subunit (VP39) of CaPVs. Hydroxynaphthol blue (HNB) was incorporated to monitor assay progress by color change from violet when negative to sky blue when positive, and results were verified by agarose gel electrophoresis. The LAMP assay was shown to be highly specific for CaPVs, with no apparent cross-reactivity to other related viruses (near neighbors) or viruses that cause similar clinical signs (look-a-like viruses). The performance of LAMP was compared to that of a highly sensitive quantitative real-time PCR (qPCR) assay. LAMP and qPCR exhibited similar analytical sensitivities, with limits of detection of 3 and 8 viral genome copies, respectively. Diagnostic specificity was assessed on 36 negative specimens, including swabs and EDTA blood from control sheep, goats, and cattle. Diagnostic sensitivity was assessed on 275 specimens, including EDTA blood, swabs, and tissues from experimentally infected sheep, goats, and cattle. Overall agreement on diagnostic test results between the two assays was 90 to 95% for specificity and 89 to 100% for sensitivity. The LAMP assay described in this report is simple to use, inexpensive, highly sensitive, and particularly well suited for the diagnosis of capripox in less well equipped laboratories and in rural settings where resources are limited.

Development and evaluation of loop-mediated isothermal amplification assay for rapid detection of Capripoxvirus.

Project description:AimThe present study was undertaken to develop a nucleic acid-based diagnostic assay loop-mediated isothermal amplification assay (LAMP) targeting highly conserved genomic regions of Capripoxvirus (CaPVs) and its comparative evaluation with real-time polymerase chain reaction (PCR).Material and methodsLyophilized vaccine strain of sheeppox virus (SPPV) was used for optimization of LAMP assay. The LAMP assay was designed using envelope immunogenic protein (P32) coding gene targeting highly conserved genomic regions of CaPV responsible for causing sheep pox, goat pox, and lumpy skin disease in sheep, goat and cattle respectively. Serial tenfold dilution of SPPV recombinant plasmid DNA was used for a calculating limit of detection. Analytical sensitivity and specificity were performed.ResultsThe test described is quick (30 min), sensitive and specific for detection of CaPVs. The described assay did not show any cross-reactivity to other related viruses that cause apparently similar clinical signs. It was found to be ten times more sensitive than conventional PCR however, 100 times less sensitive than quantitative PCR (qPCR). LAMP assay results were monitored by color change method using picogreen dye and agarose gel electrophoresis.ConclusionLAMP assay can be a very good alternative for CaPV detection to other molecular techniques requiring sophisticated equipments.

Duplex loop-mediated isothermal amplification assay for simultaneous detection of human and human male DNA.

Project description:ObjectiveScreening of human and human male DNA is necessary for forensic DNA analyses. Although quantitative real-time PCR (qPCR) is commonly used for detecting and quantifying these DNA targets, its use as a screening tool is time-consuming and labor-intensive. To streamline and simplify the screening process, we aimed to develop a duplex loop-mediated isothermal amplification (LAMP) assay capable of simultaneously detecting human and human male DNA in a single tube. We assessed the duplex LAMP assay for forensic application.ResultsFor our duplex LAMP assay, we have utilized two fluorescent probes with HEX and FAM fluorophores to specifically detect human and human male DNA, respectively. The HEX (human target) signal was detected from both the male and female DNA samples, and the FAM (male target) signal was detected from only the male DNA sample. This assay has a sensitivity of 10-1 pg of DNA for both targets. Additionally, we successfully detected the two targets in the DNA samples extracted from forensically relevant body fluids, including blood, saliva, semen, and vaginal secretions.

Rapid detection of Mycoplasma pneumoniae by loop-mediated isothermal amplification assay.

Project description:To improve the diagnosis and treatment of Mycoplasma pneumoniae (Mp) infection and reduce the misuse of antibiotics, we sought to establish a loop-mediated isothermal amplification (LAMP) assay for rapid detection of Mp.Six primers specific for the Mp P1 gene were designed, and the LAMP method was used to rapidly detect Mp. The sensitivity of the LAMP method was determined by serial dilution of the standard Mp strain FH (standard strains of Mycoplasma pneumoniae). Specificity was assessed with 17 common pathogenic microorganisms in the respiratory tract. Patient samples were collected from the Department of Respiratory and Critical Care Medicine at the 307th Hospital of Chinese People's Liberation Army from March 2016 to May 2017, examined prospectively, and compared with diagnosis by quantitative real-time polymerase chain reaction (qRT-PCR).The LAMP assay for Mp detection can be completed within 60?minutes. The minimum detection limit was 39?pg/?L, and no cross-reaction was observed with 17 common respiratory tract pathogens. Of the 125 clinical specimens tested, 43 cases were positive by LAMP assay, and 40 cases were positive by qRT-PCR (P?=?.162). All 43 samples determined as positive by LAMP test were confirmed to be Mp by Mp P1 protein sequencing.The LAMP assay is suitable for rapid detection of Mp. It has high sensitivity and specificity, and the detection results are not inferior to those of qRT-PCR.

Development of Loop-Mediated Isothermal Amplification Assay for Rapid Detection of Cucurbit Leaf Crumple Virus.

Project description:A loop-mediated isothermal amplification (LAMP) assay was developed for simple, rapid and efficient detection of Cucurbit leaf crumple virus (CuLCrV), one of the most important begomoviruses that infects cucurbits worldwide. A set of six specific primers targeting a total 240 nt sequence regions in the DNA A of CuLCrV were designed and synthesized for detection of CuLCrV from infected leaf tissues using real-time LAMP amplification with the Genie® III system, which was further confirmed by gel electrophoresis and SYBR™ Green I DNA staining for visual observation. The optimum reaction temperature and time were determined, and no cross-reactivity was seen with other begomoviruses. The LAMP assay could amplify CuLCrV from a mixed virus assay. The sensitivity assay demonstrated that the LAMP reaction was more sensitive than conventional PCR, but less sensitive than qPCR. However, it was simpler and faster than the other assays evaluated. The LAMP assay also amplified CuLCrV-infected symptomatic and asymptomatic samples more efficiently than PCR. Successful LAMP amplification was observed in mixed virus-infected field samples. This simple, rapid, and sensitive method has the capacity to detect CuLCrV in samples collected in the field and is therefore suitable for early detection of the disease to reduce the risk of epidemics.

Rapid detection of equine coronavirus by reverse transcription loop-mediated isothermal amplification.

Project description:A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the rapid detection of equine coronavirus (ECoV). This assay was conducted at 60 °C for 40 min. Specificity of the RT-LAMP assay was confirmed using several equine intestinal and respiratory pathogens in addition to ECoV. The novel assay failed to cross-react with the other pathogens tested, suggesting it is highly specific for ECoV. Using artificially synthesized ECoV RNA, the 50% detection limit of the RT-LAMP assay was 10(1.8)copies/reaction. This is a 50-fold greater sensitivity than conventional reverse transcription polymerase chain reaction (RT-PCR) assays, but a 4-fold lower sensitivity than quantitative RT-PCR (qRT-PCR) assays. Eighty-two fecal samples collected during ECoV outbreaks were analyzed. ECoV was detected in 59 samples using the RT-LAMP assay, and in 30 and 65 samples using RT-PCR or qRT-PCR assays, respectively. Although the RT-LAMP assay is less sensitive than qRT-PCR techniques, it can be performed without the need for expensive equipment. Thus, the RT-LAMP assay might be suitable for large-scale surveillance and diagnosis of ECoV infection in laboratories with limited resources.
