Microagglutination tests on 95 serum samples from coypu (Myocastor coypus), using 13 serovars of Leptospira interrogans revealed antibodies in 45 animals (47.3%), 41 of which (43.1%) were against serovar icterohaemorrhagiae, suggesting the role of the coypu as a vector of leptospirosis. Tests on serum from horses and cattle for antileptospiral agglutinins showed that infection of domestic anima...

to investigate the seroprevalence of leptospiral infection in sheep in ahvaz, southwestern iran, bloodsamples were taken from 181 female sheep. sera were stored at -20°c until use. they were initially screenedat serum dilution of 1:100 against six live antigens of leptospira interrogans serovars pomona, canicola,hardjo, ballum, icterohaemorrhagiae, grippotyphosa using the microscopic agglutinat...

Leptospiral organisms have long been presumed to be associated with the presence of equine recurrent uveitis. This project was undertaken to determine the presence of Leptospira spp. in the aqueous humor of horses with uveitis to determine if there was an association with inflammation. Thirty horses were determined to have recurrent uveitis based on clinical evaluation or history. Sixteen horse...

BACKGROUND Leptospirosis is a worldwide zoonosis that is endemic in tropical areas, such as Reunion Island. The species Leptospira interrogans is the primary agent in human infections, but other pathogenic species, such as L. kirschner and L. borgpetersenii, are also associated with human leptospirosis. METHODS AND FINDINGS In this study, a melting curve analysis of the products that were amp...

OBJECTIVE To detect leptospiral antibodies by microscopic agglutination test (MAT) in north-east of Iran. METHODS This study was conducted to evaluate prevalence of human leptospiral infections by MAT, using six current reference strains of Leptospira interrogans in north-east of Iran. A total of 285 serum samples were collected from three north-east provinces of Iran, from December, 2009 to ...

Leptospirosis is a worldwide distributed zoonosis, caused by pathogenic strains of spirochetes belonging to the genus Leptospira spp. So far, the only gold standard diagnostic method for this disease has been the Micro-Agglutination Test (MAT). The purpose of this study was to test whether a correlation exists between serological diagnosis by MAT and the presence of Leptospira spp. DNA traces i...

AbstractsObjective This is the first study was conducted to identify Leptospirosis seroprevalence and serovar distribution among healthy people in different regions Vietnam. Methods cross-sectional with 600 asymptomatic three provinces, representing for North, northern Central, South of Vietnam from November December 2019. Each participant collected a 3 ml venous bloo...

Genetic maps were constructed for Leptospira interrogans serovars icterohaemorrhagiae and pomona. Previously we independently constructed physical maps of the genomes for these two serovars. The genomes of both serovars consist of a large replicon (4.4 to 4.6 Mb) and a small replicon (350 kb). Genes were localized on the physical maps by using Southern blot analysis with specific probes. Among ...

Leptospirosis is a zoonosis, which has become serious problem, especially in areas with high rainfall. Massive leptospirosis occurs after heavy rains or floods. This study aims to analyze the types and distribution of leptospira bacteria serovars risk factors for post-flood dogs. The research was conducted from January March 2020 at Ragunan Animal Hospital independent clinics Jakarta, Bekasi, D...
