Abstract: Porcine reproductive and respiratory syndrome (PRRS) is a viral disease characterized by reproductive impairment or failure in breeding animals, and a respiratory disease in pigs of any age. Brazil is the fourth largest pork producer and exporter globally, and PRRS virus (PRRSV) infection has never been reported in the country. This study aimed to investigate the status of porcine biological samples from commercial swine herds, quarantined imported boars, wild boars and feral pigs to update PRRS information in Brazil. A total of 14,382 samples were collected from 2008 to 2020, including sera (n = 12,841), plasma (n = 1,000) and oral fluids (n = 541), comprehending 137 herds and free-living pigs in eight Brazilian states. One out of 1,000 (0.1%) plasma and 15 out of 12,841 (0.11%) serum samples tested positive for PRRSV antibodies through ELISA. Upon ELISA retesting, only the plasma sample, from one 8-day-old piglet remained positive. All sixteen previously PRRSV antibody-positive samples were tested through RT-PCR and found to be negative. The presence of false-positive or singleton reactors are quite expected. Thus, the use of different/alternative diagnostic tests is indicated for an efficient PRRSV detection. Taken together, our findings demonstrated no conclusive evidence of PRRSV infection in the tested pigs, highlighting the importance to reinforce the surveillance program to prevent the introduction and eventual dissemination of PRRSV in Brazil. |
