Ebola virus mutating, scientists say

Ebola virus mutating, scientists say | Virology News | Scoop.it
Scientists at the Institut Pasteur in France who are tracking the Ebola outbreak in Guinea say the virus has mutated.
Ed Rybicki's insight:

I would be surprised it there weren't evidence by now of adaptation to humans: never in any previous outbreak of EHD [Ebola haemorrhagic disease] has the person-person chain of transmission been sustained for so long, meaning never before has there been the opportunity for human-specific adaptations to become established.

The article points out that on consequence of mutation may be that the virus becomes less virulent, leading to a greater incidence of asymptomatic infection - of which there is already evidence from previous outbreaks, and which has been implicated in the lessening incidence of transmission because of increasing herd immunity.

However, this same property might lead to increased transmission to the non-exposed, because of a lack of signs that contacts with the infected person(s) should be avoided - and for a disease as lethal as EHD, even a reduced mortality rate still means you should avoid it at all costs.

The idea of developing a modified live measles virus vaccine as an Ebola virus vaccine vector, which is what the Institut Pasteur is apparently doing, seems to be a very good one.  Measles is still a major potential problem in that part of the world, necessitating regular infant immunisations, and coupling anti-measles with an anti-Ebola vaccine in those countries is probably very good use of both a proven vaccine and existing EPI infrastructure.

First Ebola case linked to bat play - really?

First Ebola case linked to bat play - really? | Virology News | Scoop.it

The Ebola victim who is believed to have triggered the current outbreak - a two-year-old boy called Emile Ouamouno from Guinea - may have been infected by playing in a hollow tree housing a colony of bats, say scientists.

They made the connection on an expedition to the boy's village, Meliandou.

They took samples and chatted to locals to find out more about Ebola's source.

The team's findings are published in EMBO Molecular Medicine.

Ed Rybicki's insight:

Really??  Kids played in a hollow tree where bats USED to be - and the bats in which no-one can find Ebola, are the source of the epidemic? Really??

Now even for one who is prepared to believe the worst of bats - which I am; I am on record as calling them fabulous furry flying cockroaches - the evidence here is VERY thin.

Consider the facts in evidence: 

"Villagers reported that children used to play frequently in the hollow tree"

"Emile - who died of Ebola in December 2013 - used to play there, according to his friends."

"The villagers said that the tree burned on March 24, 2014 and that once the tree caught fire, there issued a "rain of bats""

"A large number of these insectivorous free-tailed bats ...were collected by the villagers for food, but disposed of the next day after a government-led ban on bushmeat consumption was announced."

"{While] The scientists ...were unable to test any of the bushmeat that the villagers had disposed of, they captured and tested any living bats they could find in and around Meliandou."

"No Ebola could be detected in any of these hundred or so animals, however."

"But previous tests show this species of bat can carry Ebola."

So - the chain of logic goes: 

- Kids played in a tree

- One kid got Ebola

- Bats lived in the tree

- Those bats can be infected with Ebola

- Therefore the one kid was infected by those bats.

Really??  You would convict a whole community of bats for that, IN THE ABSENCE OF ANY EVIDENCE they ACTUALLY carried Ebola??

This is thin - very, very thin.  I am also quite happy to believe the Ebola outbreak started with bats, BUT this proves nothing.  More evidence, less hype!!

Ebola case confirmed in Glasgow

Ebola case confirmed in Glasgow | Virology News | Scoop.it

A healthcare worker who has just returned from West Africa has been diagnosed with Ebola and is being treated in hospital in Glasgow.

The patient, who arrived from Sierra Leone on Sunday night, is receiving treatment at Glasgow's Gartnavel Hospital.

All possible contacts with the patient are now being investigated.

Sources told the BBC the Ebola case involved a female aid worker.

NHS Scotland said infectious diseases procedures had been put into effect.

The patient has been isolated and is receiving treatment in the specialist Brownlee Unit for Infectious Diseases on the Gartnavel Hospital campus.

They returned to Scotland from Sierra Leone late on Sunday night via Casablanca and London Heathrow, arriving into Glasgow Airport on a British Airways flight at about 23:30.

China's Ebola vaccine enters clinical trials

China's Ebola vaccine enters clinical trials | Virology News | Scoop.it

An Ebola vaccine developed by a military-tied research institute has been approved to enter the human test stage, the Chinese People’s Liberation Army’s (PLA) General Logistics Department announced Thursday.

The restructured vaccine, developed by the Academy of Military Medical Sciences (AMMC), is based on the 2014 mutant gene type and especially targets the strain plaguing west Africa, Xinhua reported.

 

The vaccine is currently in the form of a freeze-dried powder, which will keep it stable for at least two weeks in temperatures of up to 37 degrees Celsius. This will make it suitable for the tropical west African region and assist with large-scale production, according to a review report by 17 experts in the field.

Looking at protists as a source of pathogenic viruses

Looking at protists as a source of pathogenic viruses | Virology News | Scoop.it

In the environment, protozoa are predators of bacteria and feed on them. The possibility that some protozoa could be a source of human pathogens is consistent with the discovery that free-living amoebae were the reservoir of Legionella pneumophila, the agent of Legionnaires' disease. Later, while searching for Legionella in the environment using amoeba co-culture, the first giant virus, Acanthamoeba polyphaga mimivirus, was discovered. Since then, many other giant viruses have been isolated, includingMarseilleviridae, Pithovirus sibericum, Cafeteria roenbergensis virus and Pandoravirus spp. The methods used to isolate all of these viruses are herein reviewed. By analogy to Legionella, it was originally suspected that these viruses could be human pathogens. After showing by indirect evidence, such as sero-epidemiologic studies, that it was possible for these viruses to be human pathogens, the recent isolation of some of these viruses (belonging to the Mimiviridae and Marseilleviridae families) in humans in the context of pathologic conditions shows that they are opportunistic human pathogens in some instances.
