Caracterização epidemiológica da leptospirose em equinos na Microrregião do Pajeú de Pernambuco, Brasil.

Abstract

Leptospirosis in horses is a major cause of abortion and reproductive failure in females and males in recurrent uveitis, causing economic losses. We conducted an epidemiological survey aimed to analyze the presence of leptospiral antibodies in horses and the main risk factors related to the disease in the properties of the microrregion from Pajeú of Pernambuco. We examined sera from 100 horses from 38 properties of four municipalities in the region, by the microscopic agglutination test, using 24 Leptospira spp. as antigens. Of the 100 samples tested, 28 (28%) were positive. The reagents serovars were Patoc (10%), Butembo (9%), sentot (4%), Australis (2%), Copenhageni (2%) and Hadjo (1%). Data analysis indicated as a risk factor as the use of pasture forage (OR = 7.80, 95% CI = 1.714 - 35.496).
