Unprecedented genomic diversity of RNA viruses in arthropods reveals the ancestry of negative-sense RNA viruses

Unprecedented genomic diversity of RNA viruses in arthropods reveals the ancestry of negative-sense RNA viruses | Virology News | Scoop.it
Although arthropods are important viral vectors, the biodiversity of arthropod viruses, as well as the role that arthropods have played in viral origins and evolution, is unclear. Through RNA sequencing of 70 arthropod species we discovered 112 novel viruses that appear to be ancestral to much of the documented genetic diversity of negative-sense RNA viruses, a number of which are also present as endogenous genomic copies. With this greatly enriched diversity we revealed that arthropods contain viruses that fall basal to major virus groups, including the vertebrate-specific arenaviruses, filoviruses, hantaviruses, influenza viruses, lyssaviruses, and paramyxoviruses. We similarly documented a remarkable diversity of genome structures in arthropod viruses, including a putative circular form, that sheds new light on the evolution of genome organization. Hence, arthropods are a major reservoir of viral genetic diversity and have likely been central to viral evolution.

Ed Rybicki's insight:

I do so love it when I'm proven right....

 

"other ssRNA viruses – such as the negative sense mononegaviruses, Order Mononegavirales, which group includes Ebola, measles and mumps and rabies viruses – may be evolutionarily much younger.  In this latter case, the viruses all have the same basic genome with genes in the same order and helical nucleocapsids within differently-shaped enveloped particles.  Their host ranges also indicate that they originated in insects: the ones with more than one phylum of host either infect vertebrates and insects or plants and insects, while some infect insects only, or only vertebrates – indicating a possible evolutionary origin in insects, and a subsequent evolutionary divergence in them and in their feeding targets."

 

Thanks to Alan Cann for pointing this out!

Interestingly, a virus was discovered in the the horsefly pool that showed sequence homology to tenuiviruses (like rice grass stunt virus) despite the fact that this virus lacked the ambisense coding strategy of teniuviruses. It was discussed that  it  possibly represents an intermediary form between plant infecting and arthropod-specific viruses.

Three-Dimensional Reconstruction of the Giant Mimivirus Particle with an X-Ray Free-Electron Laser

Three-Dimensional Reconstruction of the Giant Mimivirus Particle with an X-Ray Free-Electron Laser | Virology News | Scoop.it

We present a proof-of-concept three-dimensional reconstruction of the giant mimivirus particle from experimentally measured diffraction patterns from an x-ray free-electron laser. Three-dimensional imaging requires the assembly of many two-dimensional patterns into an internally consistent Fourier volume. Since each particle is randomly oriented when exposed to the x-ray pulse, relative orientations have to be retrieved from the diffraction data alone. We achieve this with a modified version of the expand, maximize and compress algorithm and validate our result using new methods.

In 2013, measles killed more kids than car accidents or AIDS

In 2013, measles killed more kids than car accidents or AIDS | Virology News | Scoop.it
Measles was one of the top killers of children in 2013.

Measles killed 82,100 children under age 5 in 2013, ranking the disease at No. 7 on the list of the top causes of child death, according to recent statistics from the Global Burden of Disease study published in the Lancet. Lower respiratory infections like pneumonia were the number one killer, followed by malaria, diarrhea, nutritional deficiencies, congenital defects and meningitis. More small children died from measles in 2013 than died from drowning, road injuries or aids.

Viruses Increasingly Behind Child Pneumonia Cases

Viruses Increasingly Behind Child Pneumonia Cases | Virology News | Scoop.it
WEDNESDAY, Feb. 25, 2015 (HealthDay News) -- Young children are at increased risk of becoming seriously ill with pneumonia -- but unlike in years past, the cause is usually a respiratory virus, a large U.S. study finds.

The researchers found that 66 percent of pneumonia cases in the more than 2,000 children in the study were caused by viruses alone. Just 8 percent had solely bacterial causes, and 7 percent were known to be caused by both bacteria and viruses. And, those infections can end up being serious, the study authors said.

Watch out for nasty global flu surprises, WHO warns

Watch out for nasty global flu surprises, WHO warns | Virology News | Scoop.it

By Kate and Kelland LONDON, Feb 27 - The world remains highly vulnerable to a possible severe flu pandemic and governments should increase surveillance, vigilance and preparedness, the World Health Organization (WHO) said on Friday. It said the world was fortunate that the last flu pandemic, caused by H1N1 swine flu in 2009/2010, was relatively mild, but added: "Such good fortune is no precedent". In a seven-page report on flu, WHO said that on many levels, the world is better prepared now than ever before for a flu pandemic. The level of alert is high, it said, and there is better surveillance of flu viruses in both animals and humans.
