Abstract

Leptospirosis is a zoonotic disease that poses a significant threat to human and animal health worldwide. Among different animal species, pigs are known to play a crucial role in the transmission of the pathogenic Leptospira spp. This study aimed to investigate the prevalence of Leptospira spp. infection and associated risk factors in subsistence pig production in the state of Paraná, Brazil. A total of 1393 serum samples were collected from pigs on 188 subsistence properties in different regions of the state, and tested using the microscopic agglutination test (MAT) to detect antibodies against 24 different Leptospira spp serovars. The results revealed an overall seroprevalence of 68.78% for Leptospira spp. antibodies, with Icterohaemorrhagiae, Butembo, and Pomona being the most commonly detected serovars. Poor housing conditions, lack of rodent control, absence of veterinary assistance, and a history of reproductive problems were identified as significant risk factors associated with Leptospira spp. infection in the subsistence pig population. These findings highlight the urgent need for implementing effective control measures, such as improved housing conditions, rodent control, and veterinary assistance, to prevent the spread of this zoonotic disease in subsistence pig production systems in Paraná, Brazil.
