Colorimetric reverse transcription loop-mediated isothermal amplification (RT-LAMP) as a visual diagnostic platform for the detection of the emerging coronavirus SARS-CoV-2.

COVID-19, caused by the infection of SARS-CoV-2, has emerged as a rapidly spreading infection. The disease has now reached the level of a global pandemic and as a result a more rapid and simple detection method is imperative to curb the spread of the virus. We aimed to develop a visual diagnostic platform for SARS-CoV-2 based on colorimetric RT-LAMP with levels of sensitivity and specificity comparable to that of commercial qRT-PCR assays.

Hemoculture and Direct Sputum Detection of mecA-Mediated Methicillin-Resistant Staphylococcus aureus by Loop-Mediated Isothermal Amplification in Combination With a Lateral-Flow Dipstick.

This study reports loop-mediated isothermal amplification (LAMP) for rapid detection of methicillin-resistant Staphylococcus aureus from direct clinical specimens. Four primers including outer and inner primers were specifically designed on the two target sequences-femB to identify S. aureus and mecA to identify antibiotic-resistant gene.

Rapid and sensitive detection of infectious hypodermal and hematopoietic necrosis virus by loop-mediated isothermal amplification combined with a lateral flow dipstick.

Infectious hypodermal and hematopoietic necrosis virus (IHHNV) is an important shrimp pathogen that causes mortality in Penaeus stylirostris and stunting (called runt deformity syndrome or RDS) in Penaeus vannamei. Loop-mediated isothermal amplification (LAMP) allows rapid amplification of nucleic acids under isothermal conditions. It can be combined with a chromatographic lateral flow dipstick (LFD) for highly specific, rapid and simple visual detection of IHHNV-specific amplicons.
