Cold-like infections make 'cough receptors' in the airways more sensitive, making asthmatics more prone to bouts of coughing and wheezing, reveal scientists presenting their findings at the Society for General Microbiology's Spring Conference in Dublin. The work could lead to drugs that reduce virus-induced coughing in those suffering from chronic lung diseases. Asthmatics often report bouts of coughing, wheezing and breathlessness when they have a cold and there is no current medicine...

Researchers have discovered critical new details about the structure of a virus that causes potentially fatal brain swelling and paralysis in children, pointing toward designs for antiviral drugs to treat the disease. The virus, called enterovirus 71, causes hand, foot and mouth disease, and is common throughout the world. Although that disease usually is not fatal, the virus has been reported to cause encephalitis, a potentially fatal illness found primarily in the Asia-Pacific region....

In a worst-case scenario simulation of a foot-and-mouth disease outbreak in Mexico, researchers found that establishing a good surveillance system and raising a more resilient breed of cattle could lessen the blow to the Mexican cattle industry should an outbreak of foot-and-mouth disease (FMD) or other infectious disease occur. "For diseases that spread very quickly, such as foot-and-mouth, the best way to minimize economic losses is to have a very good surveillance system," said...

Wildlife health experts from the Wildlife Conservation Society have published evidence which supports the conclusion that Mongolian gazelles–one of the most populous large land mammals on the planet–are not a reservoir of foot-and-mouth disease (FMD), a highly contagious viral disease that threatens both wildlife and livestock in Asia. Outbreaks of FMD in Mongolia affect domestic sheep, goats, camels, and cattle as well as Mongolian gazelles. In a country where roughly...

Researchers at the University of Leeds have been studying an enzyme — called 3D — which plays a vital role in the replication of the virus behind the disease. They have found that this enzyme forms fibrous structures (or fibrils) during the replication process. What's more, they have found a molecule which can prevent these fibrils forming. The project was funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and its findings have been published by the...

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...

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...
