BACKGROUND Dairy cattle were used as sentinels for the presence of Leptospira infection in Swedish livestock in four regions contrasting in precipitation and temperature during the summer time. The aim of the study was to estimate the prevalence of five serovars of Leptospira of low pathogenicity in dairy cattle in these four regions. FINDINGS Around 150 blood samples were collected from five...

Leptospira interrogans serovar icterohaemorrhagiae RGA (RGA), live or heated at 56 degrees C for 15 min or treated with Formalin, was injected into rabbits to prepare hyperimmune serum. The pathogens L. interrogans serovars icterohaemorrhagiae RGA, icterohaemorrhagiae 1, canicola Moulton, grippotyphosa Andaman, hardjo Hardjoprajitno, and pomona Pomona and the nonpathogen Leptospina biflexa sero...

The Antillean manatee (Trichechus manatus manatus), a subspecies of the West Indian manatee, inhabits fresh, brackish, and warm coastal waters distributed along the eastern border of Central America, the northern coast of South America, and throughout the Wider Caribbean Region. Threatened primarily by human encroachment, poaching, and habitat degradation, Antillean manatees are listed as endan...

An investigation was undertaken to assess the present importance of leptospiral infections in Northern Ireland, and in particular to look for evidence of infection by leptospiral serotypes other than L. icterohaemorrhagiae and L. canicola. Blood samples from 335 patients, sent to the laboratory for a variety of tests, were examined. After initial screening with five groups of pooled antigens, t...

Background: Leptospirosis is an emerging infectious disease and is considered to be the most widespread zoonotic disease in the world. LigB is an immunogenic outer membrane protein. The leptospiral ligB gene expressed only in pathogenic Leptospira spp. The aim of this study was molecular diagnosis of pathogen Leptospires by PCR based on ligB gene. Materials and Methods: Five pathogenic Leptospi...

Three pathogenic leptosipras and 12 saprophytic Leptospira biflexa strains were isolated from 72 apparently normal horse kidneys collected at an abattoir in Argentina. Cross-agglutination reaction patterns of the pathogens showed that they were antigenically homologous with members of the Hebdomadis group. When one of the strains was compared to Hebdomadis serotypes in reciprocal agglutination-...

Dr. Katharine Lunn: Over the last 10 years, the typical leptospirosis case that we have seen at the University of Wisconsin is a dog in acute renal failure. Case reports from Massachusetts, New York, New Jersey, Michigan, Georgia, and Wisconsin all suggest the same: Acute renal failure is now the most commonly reported presentation of canine leptospirosis. These reports document that the clinic...

BACKGROUND Leptospirosis is an infectious and acute disease caused by Leptospira spp. that have high epidemic potential. This study verified the main Leptospira spp. serovars detected by MAT from serum of patients with suspicion of leptospirosis from 2008 to 2012 in Minas Gerais State. METHODS The laboratory received sera from 4654 patients. All serum were screened by IgM-ELISA according to t...

To assess the distribution of specific antibodies against Leptospira spp. in Austrian adults, we conducted an explorative nationwide cross-sectional serological study in 400 healthy individuals. Antibody titres against Leptospira spp. were determined in a microscopic agglutination test using a panel of 14 serovar cultures. Sera of 18 participants were excluded because the samples were unsuitabl...

A combination vaccine (Bovi-Shield FP4 + L5, Pfizer Animal Health) containing modified-live virus (MLV) components against bovine herpesvirus-1 (BHV-1), bovine viral diarrhea virus BVDV), parainfluenza virus-3 (PI3), bovine respiratory syncytial virus (BRSV), and inactivated cultures of Leptospira canicola, grippotyphosa, hardjo, icterohaemorrhagiae, and pomona was evaluated for safety in pregn...
