High-throughput screening for respiratory pathogens within pigs in Denmark; analysis of circulating porcine respiratory coronaviruses and their association with other pathogens.

ABSTRACT: Porcine respiratory coronavirus (PRCV) typically causes subclinical or mild respiratory infections in pigs, but may lead to more severe disease with other factors. PRCV infection in Denmark was initially detected in 1984, but data are lacking about its current prevalence and diversity. Antibodies against PRCV were detected in about 75 % of recent pig sera from Denmark. In addition, pig nasal swab samples were screened for PRCV and 12 other respiratory pathogens using a high-throughput RT-qPCR system. All targeted pathogens were detected but at different prevalences. Significant associations were found between the presence of PRCV and certain other pathogens. From PRCV positive samples, partial spike gene sequences and complete nucleocapsid coding sequences were determined. In phylogenetic
