Seroprevalence of bovine vaccinia in cows and its correlation with the productive profile of affected farms in Distrito Federal, Brazil.

Bovine vaccinia (BV) is an infectious disease caused by Vaccinia virus (VACV) characterized by vesicular and exanthematic lesions, mainly in cattle. Although BV has been described in some Brazilian regions in the last decades, official information regarding the current prevalence in bovine herds of Midwestern Brazil is lacking. Thus, the current study aimed to estimate the seroprevalence and risk factors associated with BV in cattle in the Distrito Federal (DF), Brazil.

Situation of and phenotypic markers of susceptibility to helminth infection among sheep on farms in the Brazilian cerrado biome.

This study aimed to determine the intensity, seasonality, and distribution by genera of, as well as to identify phenotypic markers of susceptibility to, gastrointestinal parasites among sheep on farms within the Brazilian savanna (cerrado) biome. We evaluated 1271 sheep, on seven farms, during the rainy season (in December 2017 and December 2018) and dry season (in July 2018 and July 2019). Parasitological evaluation was based on culture and EPG.

Assessment of Internalin A Gene Sequences and Cell Adhesion and Invasion Capacity of Strains Isolated from Foods of Animal and Related Origins.

is a foodborne pathogen of global relevance that causes outbreaks and sporadic cases of listeriosis, acquired through the consumption of contaminated products, including milk or meat products and ready-to-eat meat products subjected to intensive handling. The objective of the present study was to classify isolated from various food-related sources in the Federal District of Brazil and surrounding areas to sequence internalin A () genes from these isolates and assess their adhesion and invasion capacity using Caco-2 cells. In addition, 15 were classified as group I, 3 as group II, and 7 classified as group IV.

Large-scale study of herd-level risk factors for bovine brucellosis in Brazil.

Bovine brucellosis is an important zoonosis caused by Brucella abortus that negatively impacts livestock productivity. In 2001, Brazil launched a new national program aimed at eradicating animal brucellosis that included large-scale studies of the prevalence and risk factors to support strategic decision-making. These studies were implemented by the animal health authorities and were underpinned by the scientific coordination of the University of São Paulo and the University of Brasília.

Brucellosis in working equines of cattle farms from Minas Gerais State, Brazil.

The present survey aimed at estimating the seroprevalence of brucellosis in working equines of cattle farms from Minas Gerais State, Brazil, and investigating risk factors associated with the infection. Serum samples from 6439 animals, including 5292 horses, 1037 mules and 110 donkeys, were collected from 1936 herds, between September 2003 and March 2004, in 848 municipalities from the state of Minas Gerais, Brazil. The prevalence of antibodies against smooth Brucella spp.
