Frequência de anticorpos e tentativa de isolamento de Leptospira spp. a partir do trato geniturinário de cabras (Capra hircus) abatidas no Matadouro Público Municipal de Patos - PB.

Abstract

Leptospirosis is a widespread zoonosis in the world, being an animal and public health problem. In animals, the causes related to the reproductive performance of the affected herds have the greatest impact. The present study aimed to determine the frequency of antibodies and to isolate Leptospira spp from samples of the genitourinary tract of slaughtered goats in the Public Slaughterhouse of Patos - PB. 53 goats were sampled, from which blood, kidney, bladder, urine and vaginal fluid were collected. For the detection of antibodies the Microscopic Soroagglutination (SAM) test was used. The attempt of isolation was made from urine and tissues of the genitourinary tract, using own culture media. An antibody frequency of 13.61% (7/53) was found. Antibodies were found for the serogroups Icterohaemorrhagiae (42.85%), Autumnalis (28.57%) and Tarassovi (28.57%), with titers of 100 (71.43% - 5/7) or 200 (28, 57% - 2/7). Six cultures were obtained with microorganisms with similar morphologies to Leptospira spp. In view of the above, it is possible that the low frequency and the low titres found are due to the adverse conditions offered to the agent by the environment, as well as the resistance of the goats to the infection, resulting in a lower humoral response in these animals. Therefore, in semi-arid climate conditions, a lower cut-off point in the serological test should be considered for the species in question. One-off studies that seek the isolation and typing of circulating strains in our region are necessary for the construction and application of prophylaxis and control strategies for this disease.
