Leptospirosis is the most widespread zoonosis throughout the world and human mortality from severe disease forms is high even when optimal treatment is provided. Leptospirosis is also one of the most common causes of reproductive losses in cattle worldwide and is associated with significant economic costs to the dairy farming industry. Herds are tested for exposure to the causal organism either...

Fifty sera collected from 12 different species of free-living game animals in game parks in the Northern Natal were tested against 8 Leptospira interrogans antigens using the microscopic agglutination test (MAT). Six out of 50 animals had titres, all less than 100. Three of these animals had titres to serovar mini, 1 animal to tarrasovi, and 3 animals had multi-serovar reactions, 1 to mini and ...

The prevalence of antibody to six serovars of Leptospira interrogans in cattle in Asturias (Northern Spain) was determined by the microscopic agglutination test (MAT). Using 50% agglutination or lysis at a dilution of 1:10 or more as the criteria for seropositivity, 371 of 3578 (10.36%) animals were found to react with one serovar. The most commonly detected serovars were pomona (5.59%) and gri...

leptospirosis is one of the major zoonotic diseases worldwide. this disease is caused by various serovars of leptospira interrogans sensu lato infection. although the rabbits are known to be one of the reservoirs and transmission sources of leptospirosis, but the status of this infection in rabbits in iran remains unknown, so this survey was conducted to evaluate the seroprevalence of leptos...

AIM We report a one-health investigation of three cases of leptospirosis on a dairy farm with unvaccinated cattle in New Zealand. The cases are discussed in the context of diagnostics, risk factors, persistence of symptoms and outbreak mitigation measures. METHOD Clinical and laboratory records from the human cases were reviewed and serological and molecular investigations were conducted into...
