A new approach to vaccinating cattle could help farmers worldwide, research suggests A new approach to vaccinating cattle could help farmers worldwide, research suggests. Scientists have developed a technique using a harmless parasite — which lives in cows but has no effect on their health — to carry medicines into the animals' bloodstream. Researchers created the vaccine by inserting key genetic material from a vaccine into the parasite's DNA. The manipulated parasite is...

The intestinal ecosystem is even more dynamic than previously thought, according to two studies by UT Southwestern Medical Center researchers published in the latest issue of Science. Taken together, these studies provide a new understanding of the unique intestinal environment and suggest new strategies for the prevention of inflammatory bowel disease (IBD) and viral infections, the researchers said. "Mammals have evolved ways to limit invasion by the naturally occurring bacteria that...

Don't let the warm weather fool you "“ viruses are still frequent in the summer, according to an expert at Baylor College of Medicine. "It's important for people to continue to practice good hand hygiene and cough etiquette during the summer, because there are many viruses still present," said Dr. Gail Demmler Harrison, professor of pediatrics-infectious disease at BCM and Texas Children's Hospital. Rhinovirus, enterovirus out there Viruses present in warm weather include the summer...

Anne M Stark, LLNL Skin cells shed from livestock infected with foot and mouth disease could very well spread the disease. In a new paper appearing in the Proceedings of the Royal Society B, Lawrence Livermore National Laboratory scientist Michael Dillon proposed that virus-infected skin cells could be a source of infectious foot and mouth disease virus aerosols. His proposal is based on the facts that foot and mouth disease virus is found in skin and that airborne skin cells are known to...

Cattle infected with foot-and-mouth disease are only contagious for about half as long as previously believed, according to a new study appearing Friday in the journal Science. The research has implications for the way scientists think about infectious diseases in general, said Mark Woolhouse of the University of Edinburgh, a co-author of the study.   "This study shows that what we thought we knew about foot-and-mouth disease is not entirely true," Woolhouse said. "So, what we...

By Marcia Wood, ARS Eating raw or undercooked mollusks may pose a safety hazard if they are harvested from waters polluted with pathogenic microbes, so U.S. Department of Agriculture (USDA) scientists are studying ways to enhance the food safety of these popular shellfish. For example, USDA molecular biologist David H. Kingsley at Delaware State University in Dover is exploring new techniques that will decontaminate mollusks while protecting the seafood's flavor, texture, and color. Kingsley,...

Using sinus tissue removed during surgery at University of Wisconsin Hospital and Clinics, researchers at the University of Wisconsin-Madison have managed to grow a recently discovered species of human rhinovirus (HRV), the most frequent cause of the common cold, in culture. The researchers found that the virus, which is associated with up to half of all HRV infections in children, has reproductive properties that differ from those of other members of the HRV family. The accomplishments,...

Innovation in science Groundbreaking data presented today demonstrates, for the first time, in vitro infection and replication of swine hepatitis E virus (HEV) in human hepatocytes. This study also verifies that HEV is a zoonosis (infectious disease that can be transmitted from animals to humans), which has been suggested for a long time. HEV is a major cause of epidemic and acute sporadic hepatitis in many developing countries. It is also endemic in many industrialized countries, including...

Poliovirus, the causative agent of poliomyelitis and a member of the family of Picornaviridae, is a human enterovirus. It is composed of an RNA genome that is a single-stranded positive-sense RNA. It was first isolate in 1909 and was published in 1981. It is one of the most well characterized viruses and has become a useful model system for understanding the biology of RNA viruses. It infects human cells by binding to an immunoglobulin-like receptor on the cell surface. The three...

Hepatitis A, caused by hepatitis A virus, is an acute infectious disease of the liver that is transmitted person to person by ingestion of contaminated food or water or through direct contact with an infectious person. Millions of people are believed to become infected with HAV every year. The incubation period is two to six weeks and on average is 28 days. In less developed countries the HAV is usually contracted in early childhood. Clean water helps to decrease contraction of HAV. In 90%...

Foot-and-mouth disease, FMD, is sometimes fatal and is highly contagious for cloven-hoofed animals. Along with hooved animals hedgehogs and elephants are susceptible to the disease as well. Llama and alpaca can develop mild symptoms but are resistant to the disease and don't pass it to other species. Mice, rats, and chickens have been infected artificially in a lab but it is not believed they can contract the disease under natural conditions. Humans can spread the disease by carrying the...

Human rhinoviruses are the most common viral ineffective agents in humans and are the cause of the common cold. The infection proliferates between 33-35 °C causing most reproduction to occur in the nose. It is a species in the genus Enterovirus of the Picornaviridae family of viruses. There are 99 recognized types of Human Rhinoviruses that are differentiated by their surface proteins. They are amongst the smallest viruses and lytic in nature. They travel via aerosols of respiratory...
