The objective of the present study was to determine the frequency of antibodies against leptospira spp., brucella abortus, virús da Diarreia viral bovina e Herpivirus tipo-1, In beef cattle in the State of Maranhão. Thiscross-sectionalstudywascarried out in thestateof Maranhão according to the sampling designdeveloped in the epidemiological study to evaluate the viral circulation in the proposed area for the expansion of the Vesicular Stomatitis virus in cattlefree zone with vaccination.In this work, the animals from 33 beef cattle farms from 24 municipalities of the state. The serology for BoHV-1 and BVDV were performed Immunoenzymatic Assays (ELISA), and for Leptospira spp. By means of the serum microscopic agglutination (SAM). The prevalence of herds was 66.52% for BoHV-1; 55.43% for BVDV; And 74.79% for Leptospira spp. Among the serovars of Leptospira spp. To Hardjo (42.22%) was the most prevalent in the herds, followed by Hebdomadis (35.39%). The results indicate that BoHV-1, BVDV, and Leptospira spp. Are widely distributed in cattle herds of cut, of great animal traffic, of the state of Maranhão.
