Clinical Sequencing Uncovers Origins and Evolution of Lassa Virus

Clinical Sequencing Uncovers Origins and Evolution of Lassa Virus | Virology News | Scoop.it

The 2013–2015 West African epidemic of Ebola virus disease (EVD) reminds us of how little is known about biosafety level 4 viruses. Like Ebola virus, Lassa virus (LASV) can cause hemorrhagic fever with high case fatality rates. We generated a genomic catalog of almost 200 LASV sequences from clinical and rodent reservoir samples. We show that whereas the 2013–2015 EVD epidemic is fueled by human-to-human transmissions, LASV infections mainly result from reservoir-to-human infections. We elucidated the spread of LASV across West Africa and show that this migration was accompanied by changes in LASV genome abundance, fatality rates, codon adaptation, and translational efficiency. By investigating intrahost evolution, we found that mutations accumulate in epitopes of viral surface proteins, suggesting selection for immune escape. This catalog will serve as a foundation for the development of vaccines and diagnostics.

Potentially Deadly Dengue Virus Hits Hawaii

Potentially Deadly Dengue Virus Hits Hawaii | Virology News | Scoop.it
With nearly 100 cases since September, travelers should be aware of the outbreak on the island of Hawaii. Of those cases 79 of the victims have been Hawaii residents and 13 have been visitors. "Simple measures like mosquito repellent … can greatly reduce your risk.” The fever is not spread by contact with an infected person, rather through the bite of an infected mosquito.   Last week the National Guard began assisting the health department by flying mosquito sprayers from Oahu to the Big Island. Here are the things the Hawaii health department wants you to know about the current dengue fever outbreak.  What is dengue fever?

Fossil fireworm species named after rock musician

Fossil fireworm species named after rock musician | Virology News | Scoop.it

A muscly fossil fireworm, discovered by scientists from the University of Bristol and the Natural History Museum, has been named Rollinschaeta myoplena in honour of punk musician and spoken word artist, Henry Rollins.

The fossil worm is a polychaete annelid, a marine relative of earthworms and leeches.  Polychaetes are entirely soft bodied and thus seldom occur as fossils.  When conditions are right, however, some remarkable and surprising details of such creatures can be preserved, as in the case of Rollinschaetawhich is preserved mostly as three dimensional muscle tissue.

I would have been more impressed by Jimihendrixii or Stratocasterii, but there you are.

Human genomic pathways to bronchitis virus therapy - using glow-in-the-dark coronaviruses

Human genomic pathways to bronchitis virus therapy - using glow-in-the-dark coronaviruses | Virology News | Scoop.it
Viral replication and spread throughout a host organism employs many proteins, but the process is not very well understood. Scientists at A*STAR have led a collaborative study to learn which host factors play a key role in viral replication. The aim was to identify host pathways and processes that operate at various stages of infection by a bronchitis virus that could be targeted to fight viruses.

In a recent study, Australian scientists have identified a new mosquito-carried virus, which can be used to fight human viruses.

Researchers have identified a new mosquito-carried virus, known as the Parramatta River virus, which can be used to fight human viruses, according to a collaborated study at the Universities of Queensland andSydney in Australia.

The new finding could enable scientists to development new ways for preventing outbreaks of mosquito-borne disease, according to Dr. Jody Hobson-Peters, of UQ's School of Chemistry and Molecular Biosciences.

How climate change is causing pied crow numbers to soar in SA

How climate change is causing pied crow numbers to soar in SA | Virology News | Scoop.it

Pied crows, or Corvus albus, are a natural part of the landscape of southern Africa. They are bold, common, and familiar. But over recent years, especially in South Africa, there is evidence that there are many more of these birds.


The increase is worrying some conservationists who fear it could be having a negative impact on the local biodiversity. These fears have some merit given that the species is known to predate on birds' nests and young tortoises. Farmers are also concerned about the potential damage to sheep flocks because crows pluck out the eyes of the young lambs.

 
Ed Rybicki's insight:

I find it interesting, because I grew up with these crows in central Africa - but there were none when I got to Cape Town in 1974.

Now, they're  everywhere!  So I can attest personally to their increase.

Now, about those hadeda ibises...?

Study shows that poliovirus and reovirus use fundamentally different transport mechanisms

Study shows that poliovirus and reovirus use fundamentally different transport mechanisms | Virology News | Scoop.it

This study was based upon previous work from our lab showing that host barriers restrict poliovirus dissemination in mice. Specifically, poliovirus dissemination to the central nervous system was limited by inefficient transport in neurons and by type I interferon responses (Kuss et al., PLoS Path, 2008, 4:e1000082 and Lancaster et al., PLoS Path, 2010, 6:e1000791). These discoveries were made possible by using a pool of ten genetically tagged polioviruses to follow viral population diversity during dissemination from the injection site in the leg, through the sciatic nerve, up the spinal cord, and to the brain. We wondered whether other neurotropic viruses encounter these same host barriers. To test this, we compared dissemination of genetically tagged pools of poliovirus, yellow fever virus, and reovirus. For this study, we made nine tagged reoviruses in collaboration with Terry Dermody’s lab and we used a pool of six tagged yellow fever viruses (Erickson et al., J Virol, 2013, 87:12392-7). We found that these three viruses each disseminate to the brain through different pathways.

What can we learn about the Ebola outbreak from tweets?

What can we learn about the Ebola outbreak from tweets? | Virology News | Scoop.it

The current Ebola virus disease (EVD) outbreak is of major global concern and is classified by the World Health Organization (WHO) as an international health emergency. Beginning in December 2013 in the eastern section of the Republic of Guinea,1, 2, 3 new cases were reported regularly by the Ministries of Health in Guinea, Liberia, Sierra Leone, and recently Senegal (daily direct flights to John F. Kennedy International Airport [New York, NY], Washington Dulles International Airport [Dulles, VA], and Charles de Gaulle Airport [Roissy-en-France, France]).4, 5, 6 With a cumulative case total of >13,567 (case) and 4,951 deaths,7, 8 the first major West African outbreak of the most virulent Zaire strain of EVD is now the largest EVD outbreak to date.9 Local, regional, and international agencies are challenged to contain the epidemic, reduce fatalities, and allay the climate of fear.9, 10However, ongoing disease containment and surveillance is difficult because of the current outbreak. Furthermore, in resource-limited settings, barriers to optimal public health outbreak surveillance exist.4 With Ebola in the United States and the recent New York City diagnosed case,11 there is valid cause for concern of spread in developed countries. In populated cities such as New York City, contamination is a sobering reality, and with its rodent population out numbering the humans, endemic Ebola is not outside the realm of possibility. Rodents are a main reservoir of viral hemorrhagic fevers. Similar to Lassa fever, another hemorrhagic disease, the mode of transmission is direct exposure to excreta of infected rats.12 The certainty of EVD containment in the immediate future is not known. To improve compliance with measures of prevention and control, several priority actions are recommended for strengthened surveillance systems. These include the use of emerging technologies to support early warning systems for communication between agencies and the general public.1
