| Popis: | Equine leptospirosis, although usually asymptomatic, has been associated with recurrent uveitis, abortion, and other systemic signs, constituting a major economic loss in the equine agribusiness sector. The occurrence of anti-Leptospira spp. agglutinins were investigated in 1200 serum samples of horses from 27 municipalities of the Reconcavo Baiano region, Bahia state (NE Brazil), besides the risk factors related to animals and their cattle farms. The microscopic agglutination test (MAT) was performed using 13 serogroups of Leptospira spp. as antigens. From 1200 analyzed equines, 97 (8%) were considered as positive, which obtained titer equal to or higher than 200. In 22 (78.6%) from the 28 properties, at least one animal was detected as seropositive. The most prevalent serogroup in animals, raised in stables, was the Australis (serovar Bratislava) 67%; in mounted police animals was the Sejroe (serovar Wolffi and Hardjobovis) 50%; and equestrian animals was the Australis (serovar Bratislava) 25% and Icterohaemorrhagiae (serovar Copenhageni) 25%. Equine leptospirosis is present in most cattle farms of the region studied. The risk factors of major importance regarded the semi-extensive livestock farming, the land topography of the cattle farm, the contact with animals in neighboring properties, and cohabitation with goats. |
