background and objectives: leptospirosis is an important zoonotic disease caused by leptospira interrogans . leptospirosis leads to economical losses in dairy farm industry. the objective of this study was to evaluate the pathogenic serovars of leptospira interrogans in dairy cattle herds of shahrekord by pcr. materials and methods: two hundred samples (100 urine and 100 blood) were collected f...

Leptospirosis is a zoonotic disease with global distribution that caused by pathogenic spirochetes of the genus Leptospira. Accurate diagnosis for differentiation of leptospirosis from other pyrogenic infections prevailing in the same locality and is imperative for proper treatment. Therefore a molecular diagnostic test with high specificity and sensitivity such as PCR is essential. Gene encodi...

The efficacy of vaccines against leptospiral disease can be determined objectively by challenge test in experimental animals. Selection of suitable leptospiral challenge strains and determination of an optimal challenge dose to prove exactly that the given vaccine Leptospira serotype induces protective immunity in vaccinated dogs is a critical point in performing challenge experiments. The aim ...

It is caused by antigenically distinct serovars of the parasitic species Leptospira interrogans sensu lato, of which eight are most important to dogs and cats. The disease, which is caused by serovars most commonly incriminated (...

leptospirosis is one of the zoonotic diseases caused by different serovars of the species leptospira interrogans .  the source of infection in humans is usually either direct or indirect contact with the urine of infected animals.  in this study, 400 human blood samples collected from tribal areas of farsan and koohrang cities in west centeral iran.  the serum samples were analyzed employing mi...

We aimed to determine the seroprevalence of infection with Neospora caninum, Leptospira, and bovine herpesvirus type 1 and risk factors associated with these infections in water buffaloes in Veracruz State, Mexico. Through a cross-sectional study, 144 water buffaloes (Bubalus bubalis) raised in 5 ranches of Veracruz were examined for anti-N. caninum and anti-bovine herpesvirus type 1 antibodies...

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...

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...
