Popis: A TaqMan real-time polymerase chain reaction (PCR) and loop-mediated isothermal amplification (LAMP) assay were developed to detect Gallid herpesvirus 1 (GaHV-1, formerly Infectious laryngotracheitis virus). The standard curve of real-time PCR was established, and the sensitivity reached 10 copies/μl. In the current study, the conversion between viral titer and GaHV-1 genomic copy number was constructed. Six primers for LAMP assay amplified target gene at 65°C within 45 min, and the detection limit was 60 copies/μl. The 6 primers were highly specific, sensitive, and reproducible for detection of GaHV-1. Although the sensitivity of LAMP was lower than that of real-time PCR, LAMP was faster, less expensive, and did not require a thermocycler. The LAMP assay would be a viable alternative assay in diagnostic laboratories that do not employ real-time PCR technology.
