CDC Issues Flu Vaccine Apology

For the first time we can remember, the Centers for Disease Control and Prevention are going on the record, saying the flu vaccine won't work this year.

Ed Rybicki's insight:

And so it goes: genetic drift is just a slower means of immune escape than genetic shift - and flu can do both, and does.

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.

Virulence Factors of Geminivirus Subvert Plant Resistance and Promote Vector Performance

Virulence Factors of Geminivirus Subvert Plant Resistance and Promote Vector Performance | Virology News | Scoop.it

A pathogen may cause infected plants to promote the performance of its transmitting vector, which accelerates the spread of the pathogen. This positive effect of a pathogen on its vector via their shared host plant is termed indirect mutualism. For example, terpene biosynthesis is suppressed in begomovirus-infected plants, leading to reduced plant resistance and enhanced performance of the whiteflies (Bemisia tabaci) that transmit these viruses. Although begomovirus-whitefly mutualism has been known, the underlying mechanism is still elusive. Here, we identified βC1 of Tomato yellow leaf curl China virus, a monopartite begomovirus, as the viral genetic factor that suppresses plant terpene biosynthesis. βC1 directly interacts with the basic helix-loop-helix transcription factor MYC2 to compromise the activation of MYC2-regulated terpene synthase genes, thereby reducing whitefly resistance. MYC2 associates with the bipartite begomoviral protein BV1, suggesting that MYC2 is an evolutionarily conserved target of begomoviruses for the suppression of terpene-based resistance and the promotion of vector performance. Our findings describe how this viral pathogen regulates host plant metabolism to establish mutualism with its insect vector.
