Groundbreaking data presented today demonstrates, for the first time, in vitro infection and replication of swine hepatitis E virus (HEV) in human hepatocytes.
Hepatitis A virus (HAV) is an epidemiologically important virus with a worldwide distribution and causes acute hepatitis in humans.
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 virus, called enterovirus 71, is closely related to poliovirus, and was first detected in California in the 1960s.
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.
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.

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 Â°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...
