This disclosure provides a novel serological method for detecting zoonotic viral infections, such as porcine cytomegalovirus (PCMV) infection or porcine lymphotropic herpesvirus (PLHV) infection, in subjects at any stage of disease development. More specifically, this disclosure provides an automated multiplexed immunoassay for the rapid and simultaneous detection of one or more anti-PCMV antibodies or anti-PLHV antibodies in the biological fluid of subjects suspected of being infected with PCMV or PLHV.

The invention discloses lactobacillus mucosa with porcine virus resisting activity and application of the lactobacillus mucosa, and relates to the technical field of microorganism application and virus prevention and control. It is found for the first time that the lactobacillus mucosa has broad-spectrum antiviral activity, not only has a remarkable inhibition effect on porcine reproductive and respiratory syndrome virus type 2 (PRRSV2) strains, but also can further resist porcine epidemic diarrhea virus (PEDV) and porcine rotavirus (PoRV); according to the present invention, the Lactobacillus mucosa is adopted to culture the supernatant, such that the supernatant does not have toxicity on Marc-145 cells; according to the PRRSV2 strain treated by using the supernatant, the expression level of virus RNA and protein and the filial generation virus titer are remarkably reduced, so that the infection ability is weakened; the culture supernatant directly acts with virus particles to block infection and replication of the virus particles; the product disclosed by the invention is derived from natural probiotics, is high in safety, environment-friendly and not easy to resist drugs, can be used for preparing a broad-spectrum anti-porcine virus biological preparation, provides a new strategy for preventing and controlling porcine virus diseases, and has a good industrial application prospect.
