Abstract
Pectobacterium carotovorum causing soft-rot disease requires on-site detection before the distribution of agricultural products. Loop-mediated isothermal amplification (LAMP), which is resistant to food inhibitors, is known for its high detection sensitivity for pathogens and when coupled with lateral flow immunoassay (LFA) enables visualizations. For detection of soft-rot disease, we developed a LAMP-LFA system targeting 16S ribosomal RNA, a partial sequence gene of P. carotovorum subsp. carotovorum. The LAMP-LFA was performed at 60 °C for 50 min followed by hybridization of digoxygenin-labeled LAMP amplicon and biotinylated probe. Detection sensitivity was 3.22 × 101 CFU/mL in pure culture, which specifically detected the target. In Chinese cabbage and potato, the target was detected up to low levels of 1.57 × 102 CFU/g and 1.29 × 102 CFU/g, respectively. This study showed potential applicability as a sensitive point-of-care system for soft-rot disease bacteria detection in agricultural products.

Abstract
Botrytis cinerea is a ubiquitous pathogen that can infect at least 200 dicotyledonous plant species including many agriculturally and economically important crops. In Ginseng, the fungus may cause ginseng gray mold disease, causing great economic losses in the ginseng industry. Therefore, the early detection of B. cinerea in the process of ginseng production is necessary for the disease prevention and control of the pathogen's spread. In this study, a polymerase chain reaction-nucleic acid sensor (PCR-NAS) rapid detection technique was established, and it can be used for field detection of B. cinerea through antipollution design and portable integration. The present study showed that the sensitivity of PCR-NAS technology is 10 times higher than that of traditional PCR-electrophoresis, and there is no need for expensive detection equipment or professional technicians. The detection results of nucleic acid sensors can be read by the naked eye in under 3 min. Meanwhile, the technique has high specificity for the detection of B. cinerea. The testing of 50 field samples showed that the detection results of PCR-NAS were consistent with those of the real-time quantitative PCR (qPCR) method. The PCR-NAS technique established in this study can be used as a novel nucleic acid field detection technique, and it has a potential application in the field detection of B. cinerea to achieve early warning of the pathogen infection.

Abstract
Given that the number of genetically modified (GM) maize events that have been announced as having undergone safety assessment procedures in Japan is increasing yearly, more information is needed about their actual recent domestic distribution in Japan. In this study, we investigated whether current Japanese official qualitative and quantitative methods (the current official methods) for GM maize can comprehensively target events in domestically distributed maize. For samples with the identity-preserved (IP) handling system and non-IP samples from the United States (US) and non-IP samples from Brazil, we performed event-specific real-time PCR targeting 25 authorized single GM maize events in addition to the current official methods. According to our results, 15 events targeted by the current official methods were detected, but insect-resistance (IR) Event5307 and herbicide-tolerant (HT) DAS40278, not targeted by the current official methods, were detected in the US (one out of 5 lots) and Brazilian (four out of 5 lots) non-IP samples, respectively. Nevertheless, a survey of recent GM maize acreage in recent years has revealed that more than 95% of the acreage in US maize is occupied by HT or IR/HT stacked events, and that more than 95% of the acreage in Brazilian maize is occupied by IR or IR/HT stacked events. Because the current official methods can target all stacked events related to Event5307 and DAS40278, the only undetectable events are the single Event5307 and DAS40278, whose production is estimated to be less than 5% of the total production in the producing country. Therefore, we conclude that the current official methods for the labelling of GM maize should be maintained in view of practicability.

Abstract
MON 87419 was one of the new transgenic corn events developed in US with the trait of herbicide resistance to both dicamba and glyphosate. To monitor unintended release of genetically modified organism in the future, as well as to meet GM-labeling requirements, it is requisite to develop a reliable method for the detection and quantification of MON 87419, an event-specific primer pair was designed to amplify the 3'-junction site between the endogenous genome sequence and the transferred DNA of GM event MON 87419, amplicons of desired size were produced by qualitative polymerase chain reaction (PCR) assay. For the validation of this quantitative method, the mixed samples containing 10%, 1%, and 0.1% MON 87419 ingredient were quantified. The precisions were expressed as relative standard deviations, deviated by 7.87%, 12.94%, and 19.98%, respectively. These results clearly demonstrate that the PCR methods we developed herein can be used for event-specific quantitative testing of the double-herbicide-resistant corn MON 87419.

Abstract
This study highlights the development of a multiplex real-time loop-mediated isothermal amplification assay. The developed assay employed a dual-function oligonucleotide (DFO) which simultaneously monitors the emitted amplification signals and accelerates the amplification process. The DFO was a modification of loop primer (LP); the 5'-end and 3'-end of the LP was tagged with fluorophore and quencher, respectively. The DFO was quenched in its unbound state and fluoresces only when it anneals to the specific target during the amplification process. With the same working mechanism as LP, DFO allowed the detection of target genes in less than 1 h in a real time monitoring system. We demonstrated this detection platform with Burkholderia pseudomallei, the causative agent of melioidosis. An internal amplification control (IAC) was incorporated in the assay to rule out false negative result and to demonstrate that the assay was successfully developed in a multiplex system. The assay was 100% specific when it was evaluated against 96 B. pseudomallei clinical isolates and 48 other bacteria species. The detection limit (sensitivity) of the developed assay was 1 fg/μl of B. pseudomallei genomic DNA and 18.2 CFU/ml at the bacterial cell level. In spiked blood samples, the assay's detection limit was 14 CFU/ml. The assay's diagnostic evaluation showed 100% diagnostic sensitivity, diagnostic specificity, positive predictive value, and negative predictive value. An integrated multiplex LAMP and real-time monitoring system was successfully developed, simplifying the workflow for the rapid and specific nucleic acid diagnostic test.

Abstract
Rapid tests for pathogen identification and spread assessment are critical for infectious disease control and prevention. The control of viral outbreaks requires a nucleic acid diagnostic test that is sensitive and simple and delivers fast and reliable results. Here, we report a one-pot direct reverse transcript loop-mediated isothermal amplification (RT-LAMP) assay of SARS-CoV-2 based on a lateral flow assay in clinical samples. The entire contiguous sample-to-answer workflow takes less than 40 min from a clinical swab sample to a diagnostic result without professional instruments and technicians. The assay achieved an accuracy of 100% in 12 synthetic and 12 clinical samples compared to the data from PCR-based assays. We anticipate that our method will provide a universal platform for rapid and point-of-care detection of emerging infectious diseases.

Abstract
Agrobacterium-mediated transformation is the most commonly used technique for plant genetic engineering. During the transformation, a T-DNA region, which is flanked by the right border (RB) and the left border, is transferred to plant nuclear chromosomes. Simultaneously, a sequence adjacent to the RB on T-DNA is frequently transferred to plant genomes together with the intentionally introduced recombinant DNA. We developed a novel polymerase chain reaction (PCR)-mediated detection method targeting this region. The conserved sequence of the region found in genetically modified (GM) crops is only 25 bp in length. To detect this ultrashort 25 bp sequence near the RB region, we designed a primer set consisting of a 12-base forward primer and a 13-base reverse primer. The predicted band was detected from GM crops by optimizing the PCR conditions. We used lateral flow DNA chromatography for rapid and inexpensive detection. The developed method would be applicable for screening the GM crops generated by Agrobacterium-mediated transformation.

Development of a Multiplex Loop-Mediated Isothermal Amplification (LAMP) Method for Simultaneous Detection of Spotted Fever Group Rickettsiae and Malaria Parasites by Dipstick DNA Chromatography. Diagnostics (Basel) 2020; 10:diagnostics10110897. [PMID: 33147773 PMCID: PMC7694008 DOI: 10.3390/diagnostics10110897] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 10/30/2020] [Accepted: 10/31/2020] [Indexed: 12/13/2022] Open
Abstract
Spotted fever group (SFG) rickettsiae causes febrile illness in humans worldwide. Since SFG rickettsiosis’s clinical presentation is nonspecific, it is frequently misdiagnosed as other febrile diseases, especially malaria, and complicates proper treatment. Aiming at rapid, simple, and simultaneous detection of SFG Rickettsia spp. and Plasmodium spp., we developed a novel multiple pathogen detection system by combining a loop-mediated isothermal amplification (LAMP) method and dipstick DNA chromatography technology. Two primer sets detecting SFG Rickettsia spp. and Plasmodium spp. were mixed, and amplified products were visualized by hybridizing to dipstick DNA chromatography. The multiplex LAMP with dipstick DNA chromatography distinguished amplified Rickettsia and Plasmodium targeted genes simultaneously. The determined sensitivity using synthetic nucleotides was 1000 copies per reaction for mixed Rickettsia and Plasmodium genes. When genomic DNA from in vitro cultured organisms was used, the sensitivity was 100 and 10 genome equivalents per reaction for Rickettsia monacensis and Plasmodium falciparum, respectively. Although further improvement will be required for more sensitive detection, our developed simultaneous diagnosis technique will contribute to the differential diagnosis of undifferentiated febrile illness caused by either SFG Rickettsia spp. or Plasmodium spp. in resource-limited endemic areas. Importantly, this scheme is potentially versatile for the simultaneous detection of diverse infectious diseases.

Rapid detection of rifampicin-resistant Mycobacterium tuberculosis, based on isothermal DNA amplification and DNA chromatography. J Microbiol Methods 2020; 177:106062. [PMID: 32950563 DOI: 10.1016/j.mimet.2020.106062] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Revised: 09/14/2020] [Accepted: 09/15/2020] [Indexed: 11/20/2022]
Abstract
Rapid and easy detection of nucleotide point mutations in bacterial pathogens associated with drug resistance is essential for the proper use of antimicrobials. Here, we developed a rapid and simple method for the detection of mutations using Loop-mediated isothermal amplification (LAMP) combined with the single-tag hybridization (STH) chromatographic printed array strips (PAS) method. This procedure is able to detect four mutations (C1349 T, A1295C, G1303 T, A1304 T) in Rifampicin Resistance Determining Region (RRDR) of rifampicin-resistant Mycobacterium tuberculosis (RR-TB), simultaneously. LAMP reactions contained a LAMP primer and eight allele-specific primers for each mutation. The allele-specific primers products were detected by nucleic acid chromatography using PAS. Four detection lines were detected there, one of which was detected at different positions depend on the wild type and the mutant type. We carried out the four mutations detection using 31 genomic DNA (2 A1295T, 1 G1303 T, 6 A1304 T, 22 C1349 T) from clinical isolate. The mutations have been confirmed by sequence analysis. The detection results were completely consistent with the sequence analysis. In the present study, four mutations could be detected, but only 60% of RR-TB could be detected with these four. It is expected that the detection rate will increase by adding more mutant primers. The combined LAMP and STH chromatographic PAS method is a simple and rapid method for detecting point mutations in clinical isolates as a point-of-care testing (POCT) technique. In addition, it does not require special equipment and can meet the demand in areas where drug-resistant bacteria are endemic, such as developing countries.

Abstract
The loop mediated isothermal amplification (LAMP) was developed by T. Notomi et al. in 2000. It has become one of the most promising methods for point-of-care diagnostics due to its accuracy, sensitivity and ease of execution. In this review, various methods for detecting the results of the LAMP reaction are considered; their advantages and disadvantages are revealed. Methods for detecting LAMP results can be divided into indirect and direct. Indirect methods aimed at detecting changes in the chemical composition of the reaction mixture include real-time turbidimetry, fluorescence detection with calcein, colorimetric detection with hydroxynaphthol blue, and detection using modified gold nanoparticles. Direct methods based on the detection of accumulation amplicons during the reaction include fluorimetric detection with intercalating dyes, resonance fluorescence energy transfer, enzyme immunoassay, immunochromatography, using cationic polymers and gold nanoparticles. The development in the field of point-of-care diagnostics is characterized by a pronounced tendency to miniaturization, the LAMP reaction on microchips and microfluidic devices with an electrochemical or optical detection method. The most promising for the diagnosis of infectious diseases are turbidimetry methods and the use of intercalating dyes. The development of portable domestic instruments for detecting of LAMP results based on real-time fluorescence detection or turbidimetry will contribute to the widespread introduction of the method into clinical laboratory diagnostic practice. A literature research was conducted in the Pubmed ncbi based on keywords.

Abstract
Herein, we developed a rapid method for detection of genetically modified soybean (GTS 40-3-2) products using loop-mediated isothermal amplification (LAMP). A crude 5-minute extraction method was established for DNA extraction from soybeans and soybean products. LAMP reaction for CaMV35S promoter was optimized and the fastest threshold time (Tt) was 14 min with 4 mM magnesium ions at 63 °C. A portable instrument was designed to perform real-time LAMP in the field. As little as 0.1% GM soybean, specifically, or 0.5% GM ingredients in Chinese traditional tofu could be detected in 30 min from sampling to results. We used this method to further assess other five soybean products to determine whether they contained transgenic ingredients and compared the results with those obtained using PCR, which suggested the proposed method was applicable for rapid detection of genetically modified soybean in food products.

The Development of Highly Specific and Sensitive Primers for the Detection of Potentially Allergenic Soybean ( Glycine max) Using Loop-Mediated Isothermal Amplification Combined with Lateral Flow Dipstick (LAMP-LFD). Foods 2020; 9:foods9040423.

Abstract
The soybean (Glycine max) has been recognized as a frequent elicitor of food allergy worldwide. A lack of causative immunotherapy of soybean allergy makes soybean avoidance essential. Therefore, sensitive and specific methods for soybean detection are needed to allow for soybean verification in foods. Loop-mediated isothermal amplification (LAMP) represents a rapid and simple DNA-based detection method principally suitable for field-like applications or on-site analytical screening for allergens during the manufacturing of foods. This work describes the systematic development and selection of suitable LAMP primers based on soybean multicopy genes. The chemistry applied allows for a versatile detection of amplified DNA, using either gel electrophoresis, fluorescence recording, or a simple Lateral Flow Dipstick (LFD). LAMP based on the ORF160b gene was highly specific for the soybean and may allow for a detection level equivalent to approximately 10 mg soy per kg food. Various soybean cultivars were detectable at a comparable level of sensitivity. LAMP combined with LFD-like detection facilitates a simple, highly specific and sensitive detection of the soybean without the need for expensive analytical equipment. In contrast to the majority of antibody-based methods for soybean detection, all identified primer sequences and optimized protocols are disclosed and broadly available to the community.

Abstract
Paper is a common material that is promising for constructing microfluidic chips (lab-on-a-paper) for diagnostics and drug delivery for biomedical applications. In the past decade, extensive research on paper-based microfluidics has accumulated a large number of scientific publications in the fields of biomedical diagnosis, food safety, environmental health, drug screening and delivery. This review focuses on the recent progress on paper-based microfluidic technology with an emphasis on the design, optimization and application of the technology platform, in particular for medical diagnostics and drug delivery. Novel advances have concentrated on engineering paper devices for point-of-care (POC) diagnostics, which could be integrated with nucleic acid-based tests and isothermal amplification experiments, enabling rapid sample-to-answer assays for field testing. Among the isothermal amplification experiments, loop-mediated isothermal amplification (LAMP), an extremely sensitive nucleic acid test, specifically identifies ultralow concentrations of DNA/RNA from practical samples for diagnosing diseases. We thus mainly focus on the paper device-based LAMP assay for the rapid infectious disease diagnosis, foodborne pathogen analysis, veterinary diagnosis, plant diagnosis, and environmental public health evaluation. We also outlined progress on paper microfluidic devices for drug delivery. The paper concludes with a discussion on the challenges of this technology and our insights into how to advance science and technology towards the development of fully functional paper devices in diagnostics and drug delivery.

Abstract
The purpose of this study was to assemble two types of loop-mediated isothermal amplification (LAMP) kit that have the ability to visually detect Salmonella in ready-to-eat fruits and vegetables. The reaction results were obtained within 20-40 min after addition of DNA and can be discerned by the naked eye or an amplification plot. The stability of the LAMP wet kit was evident after multiple freezing and thawing cycles, and the one-step LAMP lyophilized kit was further evolved to allow ambient temperature transport for deployment in resource-limited settings. The cost-effective wet kit had the ability to detect minimum amounts of 1.8 CFU/ml Salmonella DNA without enrichment, while the sensitivity of the one-step LAMP lyophilized kit was only 9.8 × 103 CFU/ml. They both have good anti-interference, as they were both able to detect 2.1 × 102 CFU/ml Salmonella mixed with 106 CFU/ml four non-Salmonella strain mixture. Moreover, cucumber and lettuce that were contaminated with an initial inoculation of 1.7 CFU of Salmonella/10 g showed detection within a reaction time of 30 min after 10 h enrichment. The present research setup is a convenient and practical kit for Salmonella rapid detection that has good application prospects in food safety monitoring.

Abstract
Nucleic acid-based techniques could achieve highly sensitive detection by amplifying template molecules to millions of folds. It has been one of the most valued analytical methods and is applied in many detection fields, such as diagnosis of infectious diseases, food safety assurance and so on. Nucleic acid-based techniques consist of three steps: nucleic acid extraction, amplification, and product detection. Among them, the detection step plays a vital role because it shows the results directly. As the trend of detection is simple, rapid and instrument-free, it is of necessity to carry out visual detection, where the result read-out could be visible and distinguished by the naked eye. In this critical review, advanced visual detection methods are summarized and discussed in detail, aiming to promote the potential application in on-site detection.
