Resumo
Leptospirosis is a zoonosis of worldwide distribution, caused by infection with pathogenic spirochetes of the genus Leptospira. The wild boar (Sus scrofa), an important hunting species in Europe, seems to play a significant role in the epidemiological cycle of leptospirosis. A total of 101 serum samples from wild boar hunted in Northern Portugal were analysed for leptospiral antibodies detection by microscopic agglutination test (MAT). Sera were collected during hunting seasons (2011-2013) and tested with 17 different pathogenic serovars of Leptospira. Antibodies to nine serovars were detected in 66 (65.4%) of these sera. Serovars Tarassovi and Altodouro exhibited the highest seroreactivity rates (23.8% and 16.8%, respectively), followed by Autumnalis (7.9%) and Bratislava (6.9%). Age and district of origin were found to be risk factors for the presence of leptospiral antibodies in contrast to gender. From a One Health perspective, this study revealed that wild boar should be considered as a potential source of leptospirosis dissemination for human and animals species (domestic and wild) in shared environments, particularly in the Trás-os-Montes region.
