Abstract

The Brazilian aviarist sector has great economic representation, as a demonstration of that, Brazil was the largest exporter of chicken meat in 2020, and ,To safeguard this important market, the National Poultry Health Program (PNSA) was created. The PNSA defines strategies of control and prevention for several diseases that affect poultry and the public health. Among the diseases foreseen in the PNSA, there is salmonellosis. The present study aimed to identify the prevalence of antibodies to Salmonella pullorum and Salmonella gallinarum in blood sera from free-range birds in the city of Belém, state of Paraíba. In September and October of 2021, blood samples were taken and then they were submitted to the rapid serum agglutination test in plate. A total of 120 samples were positive to the test (27.5%). From the eleven properties examined, nine had positive samples. Resulting in a prevalence of approximately 81.1%. Therefore, the data demonstrated the circulation of Salmonella Pullorum and Gallinarum strains in free-range poultry farms in the city of Belém, state of Paraíba, making it clear the necessity of more epidemiological studies that focus on that matter.
