Research Suggests That Mutagenic Drugs Designed To Kill Viruses May Make Them Stronger
As the flu season continues in full-swing, most people can appreciate the need for drugs that stop viruses after they take hold in the body. Despite this serious need for new drugs, a team of researchers from the University of Texas at Austin raise serious concerns about an emerging strategy for stopping viral infections…
Previous Flu Viruses Provided Some Immunity To Current Swine Flu, Study Shows
University of California, Davis, researchers studying the 2009 H1N1 influenza virus, formerly referred to as “swine flu,” have identified a group of immunologically important sites on the virus that are also present in seasonal flu viruses that have been circulating for years. These molecular sites appear to result in some level of immunity to the new virus in people who were exposed to the earlier influenza viruses.
Inovio Biomedical Universal Influenza Vaccines Demonstrate 100% Protection Against Current Pandemic A/H1N1 Influenza Viruses In Animal Studies
Inovio Biomedical Corporation (NYSE Amex: INO), a leader in DNA vaccine design, development and delivery, announced that the company’s SynCon? H1N1 influenza DNA vaccines achieved protection against current circulating swine origin influenza A/H1N1 viruses in animal studies.
Inviragen Researching Vaccines To Protect Against Pandemic And Seasonal Influenza Viruses
Based on its ongoing avian influenza vaccine research, Inviragen is designing vaccines to protect against multiple influenza strains, including seasonal influenza and the recently emerged H1N1 influenza strain. The H1N1 influenza virus has caused nearly 30,000 cases worldwide in 74 countries leading to 144 deaths. In contrast, while no H5N1 avian influenza strain capable of human-to-human transmission has yet emerged, the high mortality of the virus represents a threat for future epidemics.
Viruses More Virulent In A Connected World
That’s one conclusion from a new study that looked at how virulence evolves in parasites. The research examined whether parasites evolve to be more or less aggressive depending on whether they are closely connected to their hosts or scattered among more isolated clusters of hosts. The research was led by Geoff Wild, an NSERC-funded mathematician at the University of Western Ontario, with colleagues from the University of Edinburgh.
Hendra and Nipah viruses shown to be susceptible to chloroquine
Two highly lethal viruses that have emerged in recent outbreaks are susceptible to chloroquine, an established drug used to prevent and treat malaria, according to a new basic science study by researchers at Weill Cornell Medical College in the Journal of Virology.
Scientists Unravel Genetic Codes And Family Trees Of Common Cold Viruses
US scientists have unravelled the genetic code of all known strains of the common cold virus; by completing their diverse genomic sequences they were able to map not only their RNA configurations but also determine their family trees to reveal how closely they may be related and what characteristics they may or may not share as a result of mutating through neighbouring or distant evolutionary branches.
Tamiflu Remains Fully Effective Against 94 Percent Of Circulating Influenza Viruses In Europe
Latest surveillance data coming through the European Centre for Disease Prevention and Control (ECDC) from virologists and clinicians indicates that the influenza A(H3N2) virus is the predominant strain in Europe so far this season. Based on the data published by ECDC Roche confirms that the oral antiviral Tamiflu (oseltamivir) is fully active against influenza A(H3N2) and influenza B, which currently comprise 94 percent of circulating viruses in Europe this year.
The Pathogenicity of Pandemic Influenza Viruses
 |
Dr. Peter Palese, professor and chairman of the Department of Microbiology at Mount Sinai School of Medicine, shares how reconstruct the extinct 1918 pandemic influenza virus by reverse influenza viruses can help us better understand molecular basis of virulence and the mechanisms by which pandemic influenza viruses are transmitted.
