The COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, that arose in 2019 underscored significance of testing and diagnostics order to combat rapid spread disease. most common method for SARS-CoV-2 RNA detection has been RT-qPCR method, which is insufficient terms meeting immense demand due its relatively high time-consumption. Under these circumstances, urgent need a similarly sens...

Chrysanthemum chlorotic mottle viroid (CChMVd) is a serious pathogen infecting chrysanthemum worldwide. To improve and enhance the detection procedure, colorimetric loop-mediated isothermal amplifi cation (LAMP) technique was developed. Six LAMP primers were newly designed tested optimal conditions using recombinant plasmid of CChMVd as DNA template. The for incubation at 65°C 60 min. At these ...

Abstract Background Rapid spread of SARS-CoV-2 has led to a global pandemic, resulting in the need for rapid assays allow diagnosis and prevention transmission. Reverse transcription-polymerase chain reaction (RT-PCR) provides gold standard assay RNA, but instrument costs are high supply chains potentially fragile, motivating interest additional methods. transcription loop-mediated isothermal a...

Tomato mottle mosaic virus (ToMMV) is an emerging seed-transmissible tobamovirus that infects tomato and pepper. Since the first report in 2013 Mexico, ToMMV has spread worldwide, posing a serious threat to production of both crops. To prevent this virus, early accurate detection infection required. In study, we developed method for based on reverse-transcription loop-mediated isothermal amplif...

Typhoid fever remains a public health threat in many countries. A positive result in traditional culture is a gold-standard for typhoid diagnosis, but this method is time consuming and not sensitive enough for detection of samples containing a low copy number of the target organism. The availability of the loop-mediated isothermal amplification (LAMP) assay, which offers high speed and simplici...

In this study, a simple one-step reverse transcription-loop-mediated isothermal amplification (RT-LAMP) assay for rapid detection of Lassa virus (LASV) was established. The two primer sets were designed to detect LASV circulating in Sierra Leone and northeastern Nigeria. The RT-LAMP assay using these primer sets was able to detect 100 copies of the in vitro transcribed artificial LASV RNA withi...

A novel influenza A (H7N9) virus has emerged in China. To rapidly detect this virus from clinical samples, we developed a reverse transcription loop-mediated isothermal amplification (RT-LAMP) method for the detection of the H7N9 virus. The minimum detection limit of the RT-LAMP assay was 0.01 PFU H7N9 virus, making this method 100-fold more sensitive to the detection of the H7N9 virus than con...

A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for detecting the E1 gene of Chikungunya virus (CHIKV). The RT-LAMP assay is a novel method of gene amplification that amplifies nucleic acid with high specificity, efficiency, and rapidity under isothermal conditions with a set of six specially designed primers that recognize eight distinct sequences o...

Olive trees (Olea europea L.) are constantly threatened by many viruses, such as the olive leaf yellowing-associated virus (OLYaV), that belong to Olivavirus genus, family Closteroviridae. In this work, OLYaV incidence in different regions of Italy and Spain, which represent two most important European areas for production, was evaluated through development a real-time reverse transcription-loo...
