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...

Rapid antigen and antibody, serological tests, and RT ‑ PCR-based molecular methods are widely used for the detection of microorganisms worldwide. Objectives: This study aimed by Isothermal nucleic acid amplification techniques to detect the covid-19. Methods: In this study, 200 samples of nasopharynx and oropharynx were collected from Jamaran Heart Hospital in Tehran. Covid -19 was exami...

Background and Objective: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still an ongoing challenge in health system worldwide. Molecular detection methods including reverse transcription loop-mediated isothermal amplification (RT-LAMP) can help cutting off the transmission chain of the virus. In this study, prompt setting up of the RT-LAMP assays were investigated using ge...

Infectious bursal disease (IBD) is an immunosuppressive, acute and highly contagious illness of growing-poultry stock infected with infectious bursal disease virus (IBDV). It is common in Pakistan, causing potential economic losses throughout the year. The objective of the study is to propose a rapid, sensitive and specific diagnostic tool, and compare it with existing commonly used reverse tra...

successful disease management requires a rapid and sensitive diagnosis method that can recognize early infection even before the manifestation of its clinical signs. the only available field diagnostic tests for foot-and-mouth disease (fmd) are lateral flow devices, commonly known as chromatographic strips. low sensitivity and inability to detect fmd virus (fmdv) at the serotype level are limit...

We developed a useful method for the detection of rubella virus genome RNA by reverse transcription loop-mediated isothermal amplification (RT-LAMP) and compared the sensitivity of RT-LAMP with that of other virological tests: reverse transcription-PCR (RT-PCR) and virus isolation. The rubella virus genome was amplified by RT-LAMP from clinical isolates obtained between 1987 and 2004 with simil...

A reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay targeting the nucleocapsid phosphoprotein gene of infectious bronchitis virus (IBV) was developed. The detection limits for the IBV RT-LAMP assay were 10(1) 50% egg infection dose (EID(50)) per 50 microl of titrated viruses and no cross-reaction of IBV RT-LAMP was found when tested with other viruses including Newcas...
