Abstract

To define the prevalence of anti-Leptospira sp. agglutinins in ewes in the Federal District, Brazil, serum samples from 157 ewes were tested for antibodies against serovars of Leptospira sp. by the microscopic agglutination test. Antibodies were detected in three flocks in a prevalence of 3% (95%...

Abstract

An outbreak of leptospirosis in dairy cattle was observed in Santo Antonio do Monte, Minas Gerais. The herd had positive reactions in anti-Leptospira serovar Hardjo agglutination test (MAT) and had been previously vaccinated with a vaccine containing serovars Hardjo. The MAT showed 48.06% of cattle ...

Abstract

Differences in the protein profile of Leptospira sp. strains Sponselee, Norma and Hardjoprajitno were observed, with bands ranging from 175.47 kDa to 12.10 kDa. Strain Sponselee presented a 12-band profile, while strain Norma showed 11 and strain Hardjoprajitno showed 9 bands in the profile. All...

Abstract

We collected 330 serum samples from 55 dairy farms in the Basin of Caparaó, State of Espírito Santo, evaluated by microscopic agglutination (MAT) for eight serovars, found a frequency of 12.42% (41) of reactor animals for at least a serovar tested. Serovar hardjobovis presented himself as the most...

Abstract

The presence of anti-leptospira spp. aglutinins in 1360 bovine serum samples was determined in clinically healthy animals from different breeds, at more than three years old. Cattle were raised in intensive systems on 136 farms of 18 counties, 10 located in the southeast Mesoregion and 8 in the...

Abstract

It was compared the level of antibodies of sheep immunized with one or two doses of an oil bacterin produced with serovar Hardjo, type Hardjoprajitno, strain Norma, isolated from cattle urine in Brazil. Cultures of 2×108 leptospires/mL were inactivated with formalin 0.3%, final concentration and...
