Scientists Identify Proteins in Bacteria Associated with Bovine Respiratory Disease: As Possible Intervention Against the Disease

by USDA - ARS

Poor health, viruses, and environmental stress can leave young calves susceptible to secondary bacterial infections that cause bovine respiratory disease (BRD). These severe infections commonly result in pneumonia, and treatments can be costly.

To identify unique proteins that can be used for future interventions against this disease in cattle, scientists at the United States Department of Agriculture (USDA), Agricultural Research Service (ARS), took a closer look at the genetic material of multiple subtypes (strains) of three groups of bacterial species commonly implicated with BRD.

In a study recently published in Genome, U.S. Meat Animal Research Center microbiologist Emily Wynn and molecular biologist Mike Clawson examined DNA sequences from bacteria commonly found in cattle exhibiting signs of BRD. These bacteria are known as H. somni and P. multocida and M...

Making Air Travel More Sustainable with Soy-Fuel Innovations

Scientists with the Agricultural Research Service (ARS) in Peoria, Illinois, have developed a way to make a better jet biofuel from soybean oil.

Fatty acids from soybean oil can be turned into an array of industrial products normally made from petroleum, including fuel, ink and paints. One appeal of plant-based products is that they recycle carbon found in the atmosphere. This makes plants a far more renewable resource than petroleum and other fossil fuels, which add carbon to the atmosphere as they're extracted from the earth and used.

However, soy jet fuels developed to date contain insufficient amounts of "aromatic" compounds, which impart desirable density to fuel and help keep jet engine seals supple and working properly. The current shortcoming of aromatic levels in soy jet fuel means less of it can be blended with conventional jet fuels derived from petro...
