چکیده

INTRODUCTION Tuberculous lymphadenitis is the most frequent form of extrapulmonary tuberculous. Although nucleic acid amplification assays such as polymerase chain reaction have recently become mainstream techniques for diagnosing tuberculous lymphadenitis, they are still not routinely performed in developing countries because of their high costs and complicated procedures. CASE PRESENTATION We describe a case of tuberculous lymphadenitis in a 79-year-old Japanese man who had been on continuous hemodialysis for end-stage renal disease. We employed loop-mediated isothermal amplification and the procedure for ultrarapid extraction to develop a fast and easy-to-perform procedure for diagnosing tuberculous lymphadenitis. CONCLUSIONS The commercially available loop-mediated isothermal amplification assay kit and a rapid purification procedure enabled us to identify and amplify a Mycobacterium tuberculosis-specific gene within just 1.5 hours.

Loop-Mediated Isothermal Amplification (LAMP) for the Rapid Diagnosis of Herpes Simplex Virus Type 1 (HSV-1)

Background and Aims: considering difficulties in usual laboratory methods in detection of viral infections, improved DNA-based diagnostic techniques are more reliable. Loop mediated isothermal amplification method (LAMP) is a nucleic acid amplification method that amplifies DNA using six primers which has been developed to diagnose viruses as a rapid and high efficiency test. In this study, the...

A reverse transcriptase-loop mediated isothermal amplification assay (RT-LAMP) for rapid detection of bovine viral diarrhea virus 1 and 2

Bovine viral diarrhea virus (BVDV) is a pathogen that infects cattle, and is globally important. It causes substantial financial losses to the livestock industry. In the current study, a one-step reverse transcriptase-loop-mediated isothermal amplification (RT-LAMP) assay was set up for rapid and efficient detection of BVDV. For this purpose, four primers were designed to recognize six distinct...
