L eptospirosis is a worldwide zoonotic disease caused by infection with the spirochete bacterium Leptospira inteTragons.L. interrogans is further divided on the basis of antigenic relatedness into serogroupsand serovars. Approximately 200 different serovars of L. interrogans have been identified, and within a geographic region, certain serovars are prevalent and becomeadapted to a particular ma...

The prevalence of Leptospira interrogans serovars in dairy cattle was determined by analyzing 464 serum samples from cows on 15 properties in Garanhuns municipal district, Pernambuco State, Brazil. A microscopic seroagglutination test including 12 serovars of Leptospira interrogans as antigens was used. Samples with titres 100 were considered positive. Two hundred and twenty-one (47.63%) of the...

the importance of cats in the leptospira epidemiology is due to the possibility of transferring leptospirosis to wild and domesticated animals. the purpose of this survey was to determine the prevalence of leptospira infection in shorthair cats in different location of mashhad, iran. totally, 147 blood samples were taken from 42 (28.57%), 52 (35.37%) and 53 (36.05%) households, stray and cats w...

Six leptospiral strains isolated from bovine kidneys and one other strain isolated from midstream urine of a butcher were characterised. All the bovine isolates shared serological and biological properties characteristic of Leptospira interrogans but the human isolate had some characteristics of pathogenic and some of saprophytic leptospires. Although the human isolate was not recovered in cult...

A macroscopic agglutination test for detecting leptospiral antibodies in human sera is described. The test utilizes a stained preparation of non-pathogenic leptospires and is performed on the Brewer diagnostic cards used for bovine brucellosis screening. The agglutination of the stained antigen is more easily observed than the current macroscopic slide test using unstained leptospiral antigens....

ABSTRACT Bovine leptospirosis assumes great economic importance since it affects several production aspects. Therefore, knowledge about the occurrence and distribution of this disease is fundamental to adopt correct prevention measures. The present study aimed evaluate frequency anti-Leptospira spp. antibodies in 24,483 bovine serum samples received between 2007 2015 from 21 Brazilian states. O...
