Agrodiag PorCoV: A multiplex immunoassay for the differential diagnosis of porcine enteric coronaviruses.

ABSTRACT: Three different porcine enteric coronaviruses (PECs), i.e., porcine epidemic diarrhea virus (PEDV), transmissible gastroenteritis virus (TGEV) and porcine Deltacoronavirus (PDCoV) are currently circulating in U.S. commercial swine herds. Differential diagnosis of PECs relies on laboratory methods. This study describes the development of an ELISA-like multiplex planar immunoassay based on virus-specific recombinant S1 proteins printed in an array of spots at the bottom of a 96-well microplate for simultaneous detection differential serodiagnosis of PEDV, TGEV, PDCoV in a single sample. The technology overall format and working principle is similar to the solid-phase standard ELISA. After the three typical incubation steps, the reaction was visualized as blue spots which intensity correlated
