Levantamento da leptospirose em amostras de suínos do território de identidade Semiárido Nordeste II do Estado da Bahia

Abstract

The leptoptospirosis is a bacterial zoonosis that assumes considerable role as an economic and public health problem. This study aimed to detect anti-leptospira antibodies in 337 swine samples from five cities in the state of Bahia. As samples were processed by the technique of Microscopic Soroagglutination (SAM) in the field only the 19 type strains: Icterohaemorrhagiae, Copenhageni, Canicola, Gryppotyphosa, Pomona, Australis, Bataviae, Castellonis, Cynopteri, Javanica, Panama, Pyrogenes, Hardjo, Sejroe, Patoc, Tarassovi, Autumnalis, Hebdomadis e Wolffi. The occurrence of antibodies in the cities was 74,18%, being 50 (20%) of sera from the city of Adustina, 50 (20%) from Antas, 50 (20%) from Cicero Dantas, 50 (20%) from Paripiranga and 50 (20%) of Coronel João Sá. All samples were seroreactive for more than one serovar, the most frequent being Icterohaemorrhagiae 59 (23,6%), followed by Copenhageni 48 (19,2%) and Canicola 33 (13,2%). A percentage of 74.18% serum-reactants with predominance for serovarity Icterohaemorrhagiae (23.6%), Copenhageni (19.20%) and Canicola (13.20%) were observed, with a higher positivity for dilutions 1: 1600 and 1: 3200. The serum positivity of L. interrogans estimated by Generalized Linear Models presented estimates with significant values in parameters related to the breed of these animals.
