Abstract:
We compared group AStreptococcus(GAS) culture with a rapid helicase-dependent amplification (HDA) method using 1,082 throat swab specimens. The HDA method demonstrated 98.2% sensitivity and 97.2% specificity. GAS prevalence by culture was 20.7%, and it was 22.6% using the HDA method. In 35 min, the HDA method provided rapid, sensitive GAS detection, making culture confirmation unnecessary.

Abstract:
Abstract A protocol for the reverse transcription-helicase-dependent amplification (RT–HDA) of isothermal DNA was developed for the detection of tomato spotted wilt virus (TSWV). Specific primers, which were based on the highly conserved region of the N gene sequence in TSWV, were used for the amplification of virus's RNA. The LOD of RT–HDA, reverse transcriptase-loop-mediated isothermal amplification (RT-LAMP), and reverse transcriptase-polymerase chain reaction (RT-PCR) assays were conducted using 10-fold serial dilution of RNA eluates. TSWV sensitivity in RT–HDA and RT-LAMP was 4 pg RNA com

Abstract:
Listeria monocytogenes, a foodborne pathogen, is considered as one of the major problems in food safety. With strong safety regulations, a monitoring measure is essential for protecting the health and safety of consumers. Thus, a reliable monitoring method is required. In this study, a rapid assay based on a combination of helicase dependent amplification (HDA) and DNA signal detection via nucleic acid hybridization in blue silver nanoplates (AgNPls) was established. The assay started directly after short term enrichment in terrific broth using cotton ball swapping technique on seafood surface

Abstract:
Over the years, development of molecular diagnostics has evolved significantly in the detection of pathogens within humans and their surroundings. Researchers have discovered new species and strains of viruses, while mitigating the viral infections that occur, owing to the accessibility of nucleic acid screening methods such as polymerase chain reaction (PCR), quantitative (real-time) polymerase chain reaction (qPCR) and reverse-transcription qPCR (RT-qPCR). While such molecular detection methods are widely utilized as the benchmark, the invention of isothermal amplifications has also emerged

Abstract:
Rapid and accurate detection and identification of pathogens in clinical samples is essential for all infection diseases. However, in the case of epidemics, it plays a key role not only in the implementation of effective therapy but also in limiting the spread of the epidemic. In this study, we present the application of two nucleic acid isothermal amplification methods—reverse transcription helicase dependent amplification (RT-HDA) and reverse transcription loop-mediated amplification (RT-LAMP)—combined with lateral flow assay as the tools for the rapid detection of SARS-CoV-2, the etiologica

Abstract:
In this review, methods for isothermal amplification of nucleic acids are considered and analyzed, in particular, loop isothermal amplification of DNA and RNA (LAMP/RT-LAMP), helicase-dependent amplification (HDA) and recombinase polymerase amplification (RPA). The advantages and disadvantages of each of the techniques are described. The possibility of their application in the molecular diagnostics of infectious diseases is evaluated. A brief review of the literature on the use of LAMP, HDA, RPA in the diagnostics of viral, bacterial infections and diseases of protozoal etiology was conducted.

Abstract:
Molecular technique for nucleic acid amplification has become more advanced, especially isothermal nucleic acid amplification which can amplify DNA or RNA molecules at constant temperatures. This allows us to be independent of sophisticated equipment such as thermal cyclers or realtime-PCR. The feasibility of adopting molecular techniques for pathogen detection at point-of-care are approaching practical use. At present, there are various isothermal nucleic acid amplification technologies, including rolling cycle amplification (RCA), helicase-dependent amplification (HDA), recombinase polymeras

Un diagnòstic ràpid, precís i fiable és crucial per a la identificació d'una malaltia, com el càncer, on la detecció precoç pot millorar els resultants del tractament. El càncer de coll uterí és el tercer més comunament diagnosticat i la quarta causa de mort per càncer en les dones. La infecció persistent de virus del papil•loma humà d'alt risc (VPH) és la principal causa de càncer de coll uterí. Els biosensors electroquímics han rebut una important atenció a causa de les seves característiques. La seva compatibilitat amb tecnologies de microfabricació els fa atractius per al diagnòstic d'ADN

Emerging plant pathogens persist as a serious threat to the food security and stability of ecosystems, casting a looming shadow over the global economy. Plant pathogens afflicting one of the biggest threats to agriculture worldwide, capable of amplifying harvest losses by as much as 30 percent of the total global annual economic output, resulting in the depletion of food production worth billions of dollars. Therefore, it becomes important to precisely delineate the issue and explore solutions for addressing these ailments. Traditional methods are deemed insufficient in terms of precision, acc
