New Mechanism Of Drug Resistance Discovered By Scientists

Marla Vacek Broadfoot, Duke University Microorganisms like bacteria and fungi can evade treatment by acquiring mutations in the genes targeted by antibiotics or antifungal drugs. These permanent mutations were once thought to be the only way...

The Lancet The first systematic analysis of hepatitis E virus (HEV) transmission by blood components indicates that about 1 in 3000 donors in England have HEV in their plasma. The findings, published in The Lancet, suggest that around 1200 HEV-containing blood components (eg, red cells, platelets, and fresh frozen plasma) are likely to be transfused every year in England. The study retrospectively screened 225 000 individual blood donations collected in south east England between Oct,...

Temple University Health System Their approach promises a permanent cure and potential for protection against HIV The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good. "This is one important step on the path...

University Of Arizona Scientists' Fishing Expedition Reveals Viral Diversity In The Sea

University of Arizona A fishing expedition of microscopic proportions led by University of Arizona ecologists revealed that the lines between virus types in nature are less blurred than previously thought. Using lab-cultured bacteria as "bait," a team of scientists led by Matthew Sullivan has sequenced complete and partial genomes of about 10 million viruses from an ocean water sample in a single experiment. The study, published online on July 14 by the journal Nature, revealed that...

Viral Relics Reveal Cancer's 'Footprint' On Our Evolution
2014-07-21 03:57:19

University of Oxford Cancer has left its ‘footprint’ on our evolution, according to a study which examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species. Viral relics are evidence of the ancient battles our genes have fought against infection. Occasionally the retroviruses that infect an animal get incorporated into that animal’s genome and sometimes these relics get passed down from generation to generation – termed ‘endogenous...

Emory Health Sciences Bacterial defense system vs phages has unexpected functions CRISPR, a system of genes that bacteria use to fend off viruses, is involved in promoting antibiotic resistance in Francisella novicida, a close relative of the bacterium that causes tularemia. The finding contrasts with previous observations in other bacteria that the CRISPR system hinders the spread of antibiotic resistance genes. The results are scheduled for publication in PNAS Early Edition....

Penn State Mosquitoes infected with the bacteria Wolbachia are more likely to become infected with West Nile virus and more likely to transmit the virus to humans, according to a team of researchers. "Previous research has shown that Wolbachia -- a genus of bacteria that live inside mosquitoes -- render mosquitoes resistant to pathogen infection, thereby preventing the mosquitoes from infecting humans with the pathogens," said Jason Rasgon, associate professor of entomology, Penn...

Emory Health Sciences Viral fitness tracks with likelihood of transmission New research on HIV transmission shows that viral fitness is an important basis of a "genetic bottleneck" imposed every time a new person is infected. The findings define a window of opportunity for drugs or vaccines to prevent or limit infection. HIV represents evolution on overdrive. Every infected individual contains a swarm of viruses that exhibit variability in their RNA sequence, and new mutations are...

Science in Public Some viruses can hide in our bodies for decades. They make ‘fake’ human proteins that trick our immune cells into thinking ‘everything is awesome’, there’s nothing to see here. Now researchers at the Imaging Centre of Excellence at Monash and Melbourne Universities have determined the basic structure of one of the two known families of these deceptive proteins. Using synchrotron light and working with a common virus that lives in people happily and for...

Yellow fever is an acute viral hemorrhagic disease with a 40 to 50 nm enveloped RNA virus with positive sense of the Flaviviridae family. It is transmitted by the bite of female mosquitoes and is found in tropical and subtropical areas in South America and Africa, but not in Asia. Primates and a few kinds of mosquitoes are the only known hosts. The origin of the disease is most likely Africa. From there it was introduced to South America through the slave trade in the 16th century. There...

Rubella virus is the cause of congenital rubella syndrome when infection occurs during the first weeks of pregnancy. Humans are the only known host of this virus. It is the only member of the genus of Rubivirus and belongs to the family of Togaviridae. Members of the Togaviridae family typically have a genome of single-stranded RNA of positive polarity which is enclosed by an icosahedral capsid. This genome has a length of about 9,757 nucleotides and encodes for two non-structural as well...

A virus is a small infectious agent that replicates inside the living cells of organisms. It is a small infectious agent that can replicate only inside the living cells of organisms. Most are too small to be seen by anything but a microscope and they infect all organisms from animals to plants to bacteria. The first one discovered was the tobacco virus in 1898. Since then around 5,000 viruses have been described in detail although there are millions of different types. They are found in...

Vaccinia virus (VACV or VV) is a large, complex, enveloped virus belonging to the poxvirus family. It is well-known for its role in eradicating smallpox. It was the first human disease to to successfully be eradicated by science. The World Health Organization was the one who completed the endeavor. The vaccinia virus saw renewed interest in the early 21st century due to concerns about the smallpox virus being used as an agent for bioterrorism. They can be divided into four types:...

Simian immunodeficiency virus (SIV), also known as African Green Monkey virus, is a retrovirus able to infect at least 33 species of African primates. SIV has been present in monkeys and apes for at least 32,000 years, probably longer. Strains from two of these primate species have crossed the barriers into humans resulting in HIV-2 and HIV-1. Contraction involves contact with the blood of chimps that are often hunted for bushmeat in Africa. SIV infections appear in many cases to be...
