Abstract

The objective of this research was to estimate the frequency, risk factors and mapping of outbreaks in ovine flocks in the State of Maranhao, Brazil, related to Leptospira spp. A total of 575 samples of blood serum from sheep were collected, from 116 flocks, and 20 municipalities. An epidemiological questionnaire was applied to verify the association of risk factors. Microscopic Agglutination Test (MAT) was used for 24 serovars of Leptospira spp. 100% of the flocks (116) and 94.43% of animals (543/575) were reagents for at least one of the 24 serovars tested. The most frequent serovars were Sentot (236, 41.04%), Hadjo (197, 34.26%), Adamana (178; 30.95%), Pomona (158, 27.47%) and Autumnallis (148, 25.73%). The presence of rodents, felines, goats, pigs and wild animals had a statistically significant association (p < 0.05) with the occurrence of Leptospira spp. It was concluded that the frequency of Leptospiraspp was high in sheep from the State of Maranhao. However, all municipalities had infected animals, therefore, it is considered necessary to implement sanitary measures for the control and prevention of this disease in ovine flocks in the state of Maranhao.
