Dairy cows exposed to heavy metals worsen antibiotic-resistant pathogen crisis
Publicado em 25 de novembro de 2020
Dairy cows, exposed for a few years to drinking water contaminated with heavy metals, carry more pathogens loaded with antimicrobial-resistance genes able to tolerate and survive various antibiotics.
That’s the finding of a team of researchers that conducted a study of two dairy herds in Brazil four years after a dam holding mining waste ruptured, and it spotlights a threat to human health, the researchers contend.
The study is the first to show that long-term persistence of heavy [...]

Novel Dairy Cattle Breeding Method Increases Genetic Selection Efficiency
Publicado em 05 julho 2019Brazilian scientists at São Paulo State University (UNESP) collaborating with colleagues at the University of Maryland and the United States Department of Agriculture (USDA) have developed a dairy cattle breeding method that adds a new parameter to genetic selection and conserves or even improves a population’s genetic diversity. The study, which is published in Journal of Dairy Science, was funded by the São Paulo Research Foundation – FAPESP and USDA. Besides [...]ver notícia
