Spread of viruses, scientists make new discovery

Scientists have discovered gained fresh knowledge about how viruses such as flu and HIV jump between species, a finding that is expected to help predict the appearance of new diseases.

The research carried out by Edinburgh and Cambridge universities seek to understand how viruses such as bird flu infect distant species like humans.

The scientists found that the viruses were better able to infect species closely related to their typical target species than species that were distantly related.

However, the research also suggested that when diseases make a big leap they may then spread easily in species closely related to the new victim, regardless of how closely related these are to the original target species, the BBC reported.

Dr Ben Longdon, of Edinburgh Universitys school of biological sciences who led the study, said, “Emerging diseases such as Sars, HIV and some types of flu have all got into humans from other species.

By infecting more than 50 species of flies with three different viruses, the researchers showed that species closely related to a virus usual target species were more susceptible than distantly related flies.

They also showed that groups of flies that were closely related were similarly susceptible to the same viruses.

The study, funded by the Biotechnology and Biological Sciences Research Council, Natural Environment Research Council, the Wellcome Trust and the Royal Society, was published in the journal PLoS Pathogens.

Effective HIV Vaccine Announced

Hiv vaccine, Aids vaccine, Effective HIV Vaccine Announced,

In a first, an experimental vaccine was found to reduce the likelihood of contracting HIV.

It’s very far from 100% effective. Based on a trial of 16,000 participants, incidents of contracting the virus fell 31%, but that’s much more significant than has been seen in any past trials.

WSJ: The study actually tested a two-vaccine combo in a “prime-boost” approach, where the first one primes the immune system to attack HIV and the second one strengthens the response.

They are ALVAC, from Sanofi Pasteur, the vaccine division of French drug maker Sanofi-Aventis; and AIDSVAX, originally developed by VaxGen Inc. and now held by Global Solutions for Infectious Diseases, a nonprofit founded by some former VaxGen employees.

ALVAC uses canarypox, a bird virus altered so it can’t cause human disease, to ferry synthetic versions of three HIV genes into the body. AIDSVAX contains a genetically engineered version of a protein on HIV’s surface. The vaccines are not made from whole virus — dead or alive — and can’t cause HIV.

Neither vaccine in the study prevented HIV infection when tested individually in earlier trials, and dozens of scientists had called the new one futile when it began in 2003.

Obviously, one trial is just the beginning of what will probably be years of development before this turns into anything that is deemed worthwhile and scalaable. Still, it’s exciting news. Watch shares of Sanofi (SNY) to move today.
