Isolamento de leptospira spp. a partir do trato geniturinário de ovinos abatidos no Matadouro Público de Patos, Estado da Paraíba, Brasil.

Abstract

The leptospirosis is an illness thoroughly spread in Brazil that carts high economical damages for the national livestock. His/her main impact is the compromising of the reproductive acting of the attacked flocks. The present study had as objective the isolation of leptospiras pathogenic in culture means starting from the treatment sheep genitourinary, comparing the results obtained with the profile serologic of the researched animals. 80 samples of the treatment genitourinary of females and males were processed (placenta, flask of the deferential duct, vesicular glands) abated at the public slaughterhouse of Patos - PB, Brazil and, parallel, tests serologic were accomplished seeking to find antibodies of leptospirosis. For the isolation of the bacterium starting from fragments of the collected organs, the inoculation was used in middle of culture (Fletcher). The found results indicated two positive samples, among researched them. The suspicious samples were purified being inoculated in laboratory animals. The diagnosis serologic of the leptospirosis was accomplished by the microscopic soroaglutinaeao, being used 17 sorovares. For the test of microscopic soroaglutinaeao, six animals were positive with serums reagents to the sorovares Autumnalis and Icterohaemorragiae. Among the positive samples for the isolation, no animal was positive serologically to the soroaglutinaeao test.
