Spatial and seasonal distribution of Leptospira spp. seropositive horses in the Northeast region of Brazil.

Leptospirosis is an anthropozoonosis of economic and public health importance, caused by bacteria of the genus Leptospira. Horses are deemed important in its transmission chain due to their proximity to humans, and because the species is often asymptomatic, making these animals potential silent reservoirs. In this context, the objectives of this study were to determine the prevalence of seropositive horses for Leptospira spp.

Strong Evidence of the Role of Donkeys in the Epidemiology of spp. in Semiarid Conditions.

Donkeys () are historically known for their close relationship to humanity, which raises the need to study zoonotic diseases that affect them. In this perspective, leptospirosis stands out as a disease with an economic and public health impact, and its occurrence is facilitated in times of higher rainfall indexes, especially in large urban centers. In view of the scarcity of information about leptospirosis in donkeys, the objective of this study was to detect the presence of spp.

Technological characterization of sheep production systems in Brazil.

Sheep production has expanded in Brazil focusing on lamb meat, mostly to meet demanding internal markets in the state of São Paulo. Such markets present a demand which internal production is insufficient to meet. However, sheep farmers face many technical difficulties to produce quality lambs at viable costs.
