Virus to
wipe out malaria mosquitoes |
|
New York : In what could be deemed as a
remarkable medical breakthrough, American researchers have
discovered a virus which they claim is infectious to the
Anopheles gambiae mosquito that is responsible for
transmitting malaria.
According to them, the virus could someday be used to pass
on new genetic information to the Anopheles mosquitoes as
part of a strategy to control malaria, which kills over one
million people worldwide each year.
In fact, the virus, AgDNV, is a densonucleosis virus or “densovirus”,
which are very common to mosquitoes and other insects, but
do not infect vertebrate animals such as humans.
Although the virus does not appear to harm the mosquitoes,
the researchers at Johns Hopkins Bloomberg School of Public
Health have determined that it is highly infectious to
mosquito larvae and is easily passed on to humans. According
to the study’s lead author Jason Rasgon, the discovery came
about serendipitously while the research team was conducting
experiments to determine whether Wolbachia bacteria could be
used to infect An. gambiae mosquito cells. During the
analysis, they noticed an “artifact” that appeared as a
prominent band in the gel used to detect the bacteria.
“Finding artifacts such as this one during experiments isn’t
uncommon, but we decided to investigate this one further
since we kept observing it over and over. When we sequenced
it we’re surprised to learn that we found a new virus,” he
said.
“In theory, we could use this virus to produce a lethal
toxin in the mosquito or instruct the mosquito to die after
10 days, which is before it can transmit the malaria
parasite to humans. However, these concepts are many years
away,” he said. (Media Watch) |

Big B gets standing ovation from London
fans |
|
Amitabh Bachchan got a standing ovation
by a 20,000 strong audience here as he recited in his
inimitable baritone dialogues from all time hits like Deewar
and Agnipath as part of the star studded Unforgettable Show.
Bachchan became emotional while delivering dialogues from
Deewar — in which he plays an agnostic role who goes to the
temple for the first time asking God to save the life of his
mother — and said: “Whenever I do the scene I get emotional
about my mother whom I lost last year.”
Besides the three-hour long glitz, glamour of Bollywood
songs and dance sequences, performed on Sunday night,
Bachchan read out some of the poems from Agnipath (Path of
Fire), penned by his father Harivansh Rai Bachchan.
The show partners with TERI project to light a billion homes
across the globe.
“We (Unforgettable Show) have decided to light 1 billion
houses (in the world). About 1.6 billion people in the world
do not have electricity. The Lighting a Billion lives
campaign provides solar lanterns to people living in
villages that don’t have electricity,” Jaya Bachchan, said.
The event promoted by India’s Wizcraft International
Entertainment, which marks Bachchans comeback to the stage
after a gap of almost 20 years, will have its final event at
Rotherdam in Netherlands on Aug 29. They have already
performed in Toronto, Trinidad, Los Angeles, San Francisco,
Houston, New Jersey, Chicago and New York. (Agencies) |
