Capturing Replication Strategies Used By SARS Viruses In Their Bid To Spread Sep 19, 2008
SARS (corona)virus, a positive-stranded RNA virus, replicates in the cytoplasm of host cells, attaching its replication complex to intracellular membranes that it has modified for this purpose. See also. (Science Daily)

Childhood Rashes & RNA Virus Infection: Togavirus & Paramyxovirus Viral Diseases Rubella and Measles ... Childhood Rashes & RNA Virus Infection ... German Measles (rubella) and Rubeola (measles) are similar childhood infectious rashes caused by RNA viruses. (Suite101.com)
MMR vaccination provides triple shielding for children Apr 2, 2008
Measles is a very infectious disease caused by the RNA virus Morbillivirus. As such, it tends to occur as epidemics. (The Star Online, Malaysia -- News)
Killer of male moths is identified Feb 27, 2008
The researchers speculate that the RNA sequences, and the havoc they cause, originate from a novel RNA virus, but they have not yet examined their samples using electron microscopy to look for it. They havent nailed it down, but it certainly sounds like a virus, says Jaenike. (Nature News Service)
'Safe' form of Ebola created Jan 22, 2008
Ebola is an RNA virus, meaning that to modify it in the way Halfmann did one first has to make a DNA version, modify this, and then convert it back to an RNA virus. "If you have only the [RNA] virus and the cell line, it is safe," says Mhlberger. (Nature News Service)
Features Of Replication Suggest Viruses Have Common Themes, Vulnerabilities Aug 21, 2007
In a study published August 14 in Public Library of Science Biology, a team of researchers from the Howard Hughes Medical Institute (HHMI) at the University of Wisconsin-Madison describes in fine detail how an RNA virus known as flock house virus co-opts a cell's membranes to create an intracellular lair where it can safely replicate its genes ... The shared features extend to most RNA viruses and a group known as reverse transcribing viruses, which include retroviruses such as HIV, suggesting a... (Science Daily)
Mutation in gene made West Nile a crow killer Aug 14, 2007
West Nile virus is an RNA virus its genetic material being composed of RNA, rather than DNA. Although RNA and DNA molecules differ somewhat in structure and function, both play key roles in enabling cells to build the proteins necessary for reproducing and carry out the cells' functions. The researchers analyzed the evolutionary relationships of the West Nile virus genomes, or entire collections of genes, for 21 different strains of West Nile viruses that had been sampled globally in recent...

Uganda: Ebola-Like Virus Hits Western Town Aug 1, 2007
Caused by a genetically unique animal-borne RNA virus of the 'filovirus' family, its recognition led to the creation of this virus family. The four species of Ebola virus are the only other known members of the filovirus family. (allAfrica.com)
Japan's DNAVEC and IAVI partner on novel AIDS vaccine strategy Jul 10, 2007
Sendai, which serves as a basis of the vector, is a RNA virus that does not cause disease in humans, is capable of efficiently delivering genes expressing HIV proteins to the immune system, and of replicating safely in the upper airway. DNAVEC and the Japanese National Institute for Infectious Diseases (NIID) have demonstrated that monkeys can be protected against SIV, a virus that causes a disease in some non-human primates that is much like AIDS, if vaccinated intra-nasally using a recombinant...

Polly Roy: Rhapsody in Blue May 2, 2007
To create the vaccine, Roy stripped the double-stranded RNA virus back to its component parts and now feels she completely understands Blue Tongue's genetic and molecular make-up. So what's left to do. (Guardian Unlimited -- Life)
BVD Persistently Infected Cattle Are Complicated to Control Mar 9, 2007
Replication mistakes are common in Bovine Virus Diarrhea (BVD) because it is a RNA virus, as compared to a DNA virus ... "DNA makes the same copy much more reliably, but an RNA virus when it starts making copies, it potentially makes a huge variety of copies, different kinds of copies.". (Agri-View, WI)
Laos bird flu case h5 type avian flu Mar 5, 2007
Like all other influenza A subtypes, the H5N1 subtype is an RNA virus. Since 2004, some 270 humans have been infected with bird flu in 10 countries, with about 167 fatalities, mostly in Asia, according to the World Health Organization. (SpiritIndia)
