Ancient origins of viruses disclosed: Fresh research transforms understanding of virus origins & evolution
The investigators disclosed 214 novel RNA viruses (where the genomic material is RNA rather than DNA) in clearly healthful reptiles, amphibians, lungfish, ray-finned fish, cartilaginous fish & jawless fish. "For the premier time we could definitely display which RNA viruses are many millions of years old, & have been in existence ever ever the premier vertebrates existed. But, Professor Holmes was too quick to emphasise which these fish viruses don't pose a danger to human health & ought be viewed as a natural portion of virus biodiversity. The newly disclosed viruses appeared in every family or genus of RNA virus associated by vertebrate contagion, including those containing human pathogens like Flu virus. Because the evolutionary histories of the viruses generally matched those of their vertebrates, the investigators were enable to of conclude which these viruses had long evolutionary histories.
Bats to blame for pig-killer virus in China – research
referring to A secret germ which killed almost25,000 piglets in China in 2016/17, came from horseshoe bats, the same species which gave America the deathly human SARS virus, investigators said Wednesday. The virus, the team found, came from horseshoe bats in a zone near the birthplace of SARS — Severe Acute Respiratory Syndrome — some 15 years ago. Highly infectious & deathly, the SARS virus killed almost800, almost 1 in 10. The research findings ought serve as "a caution of viral interspecies commute among wildlife & domestic animals," research co-author Zhengli Shi told AFP. It too underlined "the importance of long-term surveillance for viruses in their natural reservoirs."This doesn't mean we ought go out & kill all horseshoe bats, added Shi.collected by :Sandra Alex
