Antibiotics, bacteria, resistance genes found in dust from feedlots

Posted by External 2 days ago General — Researchers are beginning to understand how antibiotic-resistant bacteria travel aerially. "Everyone is fairly certain antibiotic resistance comes from extensive use of antibiotics in animal-based agriculture. About 70 percent of all antibiotics used are for animal agricultural purposes. Overuse contributes to antibiotic resistance. But how does it happen? How does it get from where the drugs are Read More

Many animals steal defenses from bacteria: Microbe toxin genes have jumped to ticks, mites and other animals

Posted by External 61 days ago General — Bacteria compete for resources in the environment by injecting deadly toxins into their rivals. Researcher have now discovered that many animals steal toxins from bacteria to fight unwanted microbes growing on them. Genes for these toxins have jumped from bacterial to animals. These genes are now permanently incorporated into the genomes of these animals. Deer ticks, which can carry Lyme disease, Read More

Ancient genetic program employed in more than just fins and limbs: Hox genes provide blueprint for a diversity of body plan features

Posted by External 66 days ago General — Researchers have found that the Hox gene program, responsible for directing the development of fins and limbs, is also utilized to develop other body part features of vertebrates, such as barbels and vents in fish. The research indicates that this genetic program, which dates back at least 440-480 million years, is older and more widely utilized than previously thought. Read More
