Simultaneous detection of 4 prototypic rat parvoviruses using the luminex xTAG assay in laboratory animal health monitoring.

There are currently four rat parvoviruses including Kilham rat virus (KRV), Toolans H-1 parvovirus (H-1virus), rat parvovirus type 1a (RPV-1a) and rat minute virus (RMV). Virus detection methods are commonly based on conventional PCR - agarose gel electrophoresis or serological assay methods These methods are both time-consuming and lack specificity. In this study, we developed a bead array xTAG assay for the simultaneous detection and discrimination of four rat parvoviruses. The detection limits ranged from 100 to 1000 copies/μL of input purified plasmid DNA. We examined 50 clinical specimens and 15 facal samples by xTAG assay and conventional PCR. The results showed a high consistency except for several weak positive infections. It demonstrated that the xTAG-multiplex PCR method is specific, sensitive and suitable for high throughput platforms for rat parvovirus screening of clinical samples and contaminated biological materials.
