Plain-English summary
Researchers have developed a new test to quickly and accurately detect a virus called porcine hokovirus (PHoV) in pigs. This test, known as loop-mediated isothermal amplification (LAMP), is designed to be simple and does not need special equipment, making it useful both in labs and on farms. The test is very specific to PHoV and does not confuse it with other similar viruses. It can detect very small amounts of the virus, making it ten times more sensitive than traditional testing methods. Overall, this new LAMP test is an effective tool for identifying PHoV in pigs.
Abstract
Hokoviruses have recently been detected as pathogens belonging to the family Parvoviridae, which comprises porcine hokovirus (PHoV) and bovine hokovirus (BHoV). In this study, we developed a loop-mediated isothermal amplification (LAMP) assay for the rapid, specific and sensitive detection of PHoV. A set of four primers specific for six regions within the PHoV VP1/2 genes was designed using online software. The reaction temperature and time were optimized at 65°C and 60 min, respectively. LAMP products were detected by agarose gel electrophoresis or by visual inspection of a color change caused by a fluorescent dye. The method was highly specific for PHoV, and no cross-reaction was observed with porcine circovirus type 2 (PCV2), porcine parvovirus (PPV), porcine bocavirus (PBoV), pseudorabies virus (PRV), porcine reproductive and respiratory syndrome virus (PRRSV), classic swine fever virus (CSFV), or Japanese encephalitis virus (JEV). The detection limit was approximately 10 copies per reaction, which was 10 times more sensitive than conventional PCR. Furthermore, the efficiency of detection of PHoV in clinical samples was comparable to that of PCR and sequencing. These results show that the LAMP assay is a simple, rapid, sensitive and specific method for detecting PHoV. It does not require specialized equipment and can be used to detect PHoV both in the laboratory and in the field.
