ABSTRACT

Leptospirosis is a great of importance in public health zoonosis, Leptospira sp. it is considered to be one of the most responsible bacterias for reproductive problems in cattle. The objective of this study was to investigate the frequency of leptospirosis in cattle from 14 of the 18 districts in the Southwest region of the state of Goias. A total of 2,006 blood serum samples were analyzed by the microscopic serum agglutination test (SAM) against a battery of 32 leptospira serovars, where titers of 100 or greater were considered positive. The frequency of bovine leptospirosis in this region was 70.1 %. The most probable serovar was Guaricura (30.80%), followed by Wolffi (30.51%), Shermani (9.39%), Hardjo (7.54%), Bananal (4.27%) and Pomona serovars. (3.27%). The results shows that Leptospirosis is widespread among cattle in this region, therefore, this verifies the importance of implementing efficient and targeted control measures for the main sources of infection, being systematic vaccination with use of serovars prevalente in the region one of most importante measures for the prevention of leptospirosis.
