Caracterização epidemiológica da leptospirose em ovinos deslanados do Semiárido da Paraíba.

Abstract

Epidemiological characterization of leptospirosis in hairless sheep from the semiarid region of Paraíba. Leptospirosis is a illness prevalent spread in Brazil that cause to high economic lasses for nation livestock. Its main impact is the impairment of reproductive performance of herds affected. This work had as objective to determine the prevalence in the positive properties (focus) to sheep leptospirosis in semiarid of Paraíba; to determine the prevalence of seropositive in sheep without wool and the isolately of Leptospira spp. through of urine of seropositive animals. Were researched anti-lepitospira agglutinins in sheep from the mesoregion of semiarid of Paraíba, Brazil August of 2011 to July of 2012, in total 246 sero of sheep from seven herds in seven cities by the microscopic agglutination test, using 24 Leptospira spp., serovars as antigens. From 246 samples tested, 15(6,09%) animals were positive for more sorovar. Of seven properties, five (57,1%) had positive animals. The Characterization of sorovars mast likely took into consideration the tiration and frequency. The mast likely distribution of serovars was: Autumnalis (40%), Patoc (26,66%), Andamana (20%), Hardjo (13,33%).
