Life-threatening cardiac arrhythmia can be a consequence of myocarditis "“ an inflammation of the cardiac muscle that can be caused by the Coxsackievirus. In mice, Dr. Yu Shi, Chen Chen, and Professor Michael Gotthardt of the Max Delbrck Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now abolished the infection by blocking the receptor which is required for virus entry. "We did not detect a single cardiomyocyte that was infected by the virus. Inflammation of the heart...

U.S. scientists studying the rhinovirus genome say they've discovered how and where evolution occurs in the genome and what that means for possible vaccines. There are a lot of different approaches to treating the cold, none of which seem to be effective, said Brigham Young University Professor Keith Crandall, a co-author of the study. This is partly because we haven't spent a lot of time studying the virus and its history to see how it's responding to the human immune system and drugs. The...

A new study by Brigham Young University researchers on the virus behind nearly half of all cold infections explains how and where evolution occurs in the rhinovirus genome and what this means for possible vaccines. The study is reported in the April issue of the academic journal Molecular Biology and Evolution. "There are a lot of different approaches to treating the cold, none of which seem to be effective," said Keith Crandall, professor of biology and co-author of the study. "This is...

Vietnamese agriculture officials say hoof-and-mouth disease has been detected in nine provinces during the past three weeks The latest outbreak was reported in central Quang Ngai province, where 19 cows were found to be infected, the Voice of Vietnam radio reported Tuesday. Fifty cows were also found to be infected in Nghe An province. Bird flu has been reported in 10 provinces in the past three weeks and two provinces are dealing with outbreaks of blue ear pig disease, the report said.

A new study has shed light on the secrets of the common cold, researchers reported on Thursday. Scientists at the University of Maryland School of Medicine, the University of Wisconsin-Madison and the J. Craig Venter Institute collaborated to sequence and analyze the cold virus. As a result, they were able to configure a family tree of the common cold. "We've had bits and pieces of these things for a long time," said Ann Palmenberg, of UW-Madison's Institute for Molecular Virology and the...

First comprehensive sequencing and analysis of strains responsible for common cold and other respiratory illnesses, give clues to evolution and diversity of the virus ROCKVILLE, Md., Feb. 12 /PRNewswire-USNewswire/ -- A team of researchers from the J. Craig Venter Institute (JCVI); the University of Maryland School of Medicine and the University of Wisconsin, Madison; announced today they have sequenced and analyzed the genomes of all known human rhinoviruses (HRVs). David Spiro, Ph.D.,...

Common colds typically cause a week of sneezing, aches and pains and then fade away leaving only a sore nose and a few used sick days behind. But what if that cold turned out to be something more?Human adenovirus type-3 is known as the "uncommon cold" because the infection's symptoms"”runny nose, sore throat, cough and fever"”are eerily similar to those of the common cold which is caused by the rhinovirus. The difference is that, unlike the common cold, the symptoms of the...

CINCINNATI, Oct. 24 /PRNewswire/ -- Today, scientists from Procter & Gamble (P&G), the University of Calgary and the University of Virginia announced results from the first study to examine the entire human genome's response to the most common cold virus, human rhinovirus. The research confirmed, at the genomic level, that the immune system response to the virus, and not the virus by itself, results in common cold symptoms. Data generated by the study will be crucial in the search...

Researchers seek to understand, and improve, virus that can infect lung cancer cells The 3-D structure of the virus, known as Seneca Valley Virus-001, reveals that it is unlike any other known member of the Picornaviridae viral family, and confirms its recent designation as a separate genus "Senecavirus." The new study reveals that the virus's outer protein shell looks like a craggy golf ball "” one with uneven divets and raised spikes"”and the RNA strand beneath it is arranged in...

KUCHING: Sarawak is on high alert for the hand, foot and mouth disease after one Enterovirus 71 (EV71) case was detected following the death of a 4-year-old boy from Sibu last week. Deputy Chief Minister Tan Sri Dr George Chan said the Health Department was stepping up prevention and control measures. From the department's statistics released yesterday, 5,686 cases of HFMD had been reported so far this year. Kuching received the highest number of reported cases with 2,187, followed by...

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...
