Abstract


The aim of this work was to demonstrate the association between microscopic kidney´s lesions and presence of antibodies against Leptospira spp in apparently healthy swine from slaughterhouses located in northern Paraná State. Samples of kidney and blood coagulum were collected from 120 animals with macroscopic kidney´s lesions type white spots and from120 animals without macroscopic lesions, used as control. Samples of serum, were submitted to microscopic agglutination test (MAT) and samples of kidney for histopathological evaluation stained with Hematoxylin and Eosin (HE). Although no association (p=0,27) between macroscopic kidney’s lesions type white spots and presence of antibodies against Leptospira spp has been observed, there was a significant association (p=0,015) between interstitial nephritis and seropositivity to leptospirosis.
