Simple and rapid method for routine screening of bovine leukemia virus by loop-mediated isothermal amplification assay
نویسندگان
چکیده
Various techniques for screening and detection of bovine leukemia virus (BLV) were compared to ascertain a rapid and simple technique for routine examination. The performance of real-time PCR, nested PCR and loop-mediated isothermal amplification (LAMP) assays was compared using DNA extracted from whole blood instead of white blood cells (WBCs) of 23 cattle. Real-time PCR, LAMP and nested PCR detected 18, 16 and 11 BLV-positive cattle, respectively. These results suggest that LAMP using DNA from whole blood could enable rapid examination, as isolation of WBCs and electrophoresis is time-consuming and could be useful as a simple and rapid method for routine screening of BLV.
