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...

Hepatitis A virus (HAV) is an epidemiologically important virus with a worldwide distribution and causes acute hepatitis in humans. Acute HAV superinfection causes severe liver disease, acute liver failure and even higher mortality rates in patients with underlying chronic liver disease (CLD). Numerous studies have identified CLD as a risk factor for fulminant hepatitis and death from acute HAV infection. A research article to be published on January 14, 2011 in the World Journal of...

Says National Research Council A new National Research Council report requested by Congress finds "several major shortcomings" in a U.S. Department of Homeland Security assessment of risks associated with operating the proposed National Bio- and Agro-Defense Facility (NBAF) in Manhattan, Kan. The laboratory would study dangerous foreign animal diseases -- including the highly contagious foot-and-mouth disease (FMD), which affects cattle, pigs, deer, and other cloven-hoofed animals -- and...

The virus, called enterovirus 71, is closely related to poliovirus, and was first detected in California in the 1960s. Since then the virus has spread across Asia, affecting mostly children and some adults. Serious cases of the disease can include neurological disorders such as meningitis, paralysis and encephalitis. As a result of a global health campaign, polioviruses have almost been eradicated in many areas of the world. Enterovirus 71, however, has caused major outbreaks of hand, foot,...

In Korea, there has been a rapid epidemiological shift in hepatitis A virus (HAV) infection as a result of rapid economic development. The adult cases of acute hepatitis A have increased rapidly during the past 10 years due to the emergence of susceptible adults in Korea. After 2000, symptomatic cases of HAV infection markedly increased and the age of affected patients was significantly higher before 2000 than after 2000. This transitional pattern also has been reported in other Asian...

Combining technology and animal health, a group of Kansas State University researchers is developing a more effective way to predict the spread of foot-and-mouth disease and the impact of preventative measures. The researchers are finding that if a foot-and-mouth disease outbreak is not in the epidemic stage, preemptive vaccination is a minimally expensive way to halt the disease's spread across a network of animals. But if there's a high probability of infection, computer models show that...

BEIJING, Dec. 28 /PRNewswire-Asia/ -- Sinovac Biotech Ltd. (Nasdaq: SVA), a leading provider of biopharmaceutical products in China, announced today that it has filed the application with China's State Food and Drug Administration (SFDA) to commence a human clinical trial for its vaccine against human enterovirus 71 (EV 71), which causes hand, foot, and mouth disease (HFMD). This is the first clinical trial application for HFMD vaccine submitted in China. No vaccine or antiviral...

New research from The Children's Hospital of Philadelphia sheds light on the role of cell receptors in acting as gatekeepers for infectious viruses. By using mice genetically engineered to lack a particular receptor in heart and pancreas cells, the study team prevented infection by a common virus that causes potentially serious diseases in humans."This finding is a step to understanding how cell receptors operate in infections," said study leader Jeffrey M. Bergelson, M.D., a pediatric...

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...
