State officials take steps to avoid spread of avian influenza in dairy cattle

The U.S. Department of Agriculture (USDA) Animal Plant Health Inspection Service (APHIS) has confirmed highly pathogenic avian influenza (HPAI) in dairy herds in Texas, Kansas, Michigan, Idaho, and New Mexico.

Symptoms of the virus in dairy cattle include decreased lactation, low appetite, and thickening of milk.

To date, there have been no reported cases of HPAI in livestock within Arkansas, the state’s Department of Agriculture has reported. The Centers for Disease Control and Prevention (CDC) confirmed that a dairy farm worker tested positive for HPAI in Texas on April 1.

UAMS Study: An Antibody Could Be Cause Of Long-Term COVID Symptoms

,

By ALEXANDRIA BROWN

Researchers at the University of Arkansas for Medical Sciences say they have discovered an antibody that may be the cause of long-term COVID-19 symptoms.

The study shows some patients who contract COVID-19 have responses where their bodies produce a second antibody called autoantibody. The antibody then attacks an enzyme called ACE2 that balances the body's response to the virus. When the second antibody attacks ACE2, it causes organs to not function properly.

Dr. John Arthur, director of nephrology at UAMS and one of the lead researchers, said he and his team focused on the enzyme because they estimated there was an increase in immune system activation.

UAMS Research Team Finds Potential Cause of COVID-19 ‘Long-haulers’

,

By David Robinson

Sept. 9, 2021 | LITTLE ROCK — A UAMS research team has identified a potential cause of long-lasting symptoms experienced by COVID-19 patients, often referred to as long-haulers. The findings were published in the journal, The Public Library of Science ONE (PLOS ONE).

At the heart of the team’s findings is an antibody that shows up weeks after an initial infection and attacks and disrupts a key regulator of the immune system, said lead researcher John Arthur, M.D., Ph.D., professor and chief of the Division of Nephrology in the UAMS College of Medicine, Department of Internal Medicine.

As many as 30% of COVID-19 patients experience lingering fatigue, brain fog and shortness of breath. The cause of long COVID-19 has eluded scientists, but the UAMS team’s discovery sheds important new light on the molecular-level mechanisms behind it.
