German Media Breaks Silence, Reports Evidence Swine <deleted> Virus Came From Lab

The swine flu virus may have originated because it was sloppy work in a lab - at least an Australian researcher says. The WHO, however, comes from a natural origin.

The theory of the retired Australian virologist Adrian Gibbs of the origin of the swine flu sounds like a scenario from a disaster film: As some scientists tinkering in the lab on a vaccine against different influenza viruses that infect pigs. Work, perhaps not quite clean. Or to infect cell lines for cultivation of virus with multiple strains. Combine snippets of DNA from three different strains are infected to a new virus that humans can. A laboratory employee has the flu pathogen outside - and begins a worldwide pandemic.

The fact is: The origin of the swine flu virus is still unknown. Components of its genome have similarities with eight different influenza viruses that were discovered from 1983 to 2004 in humans, birds and pigs. Gibbs is in his investigations to the conclusion that the new H1N1 pathogen probably goes back to three strains of the virus, which attacked in the past Pigs in the United States and Eurasia. Viruses are propagated in cell cultures

Scientists assume that the original strains of the virus by migratory birds, or trade in pigs came from one continent to another. In an animal that was infected by different pathogens, and finally emerged, the new virus. Gibbs, however, considers the coincidence of the origin of strains in a laboratory to be more probable: "It would be by far the simplest explanation."

Back in May this year, he submitted to the World Health Organization (WHO) in his theory. Now, he published his hypothesis, together with two colleagues in the online journal Virology Journal. The research team wrote: "It is important that the origin of the virus is detected, if we want to prevent future pandemics, instead of fighting after they occur, only the consequences."

Massentierhaltung favors flu in pigs

In the professional world Gibbs hypothesis is viewed with skepticism. Already, the WHO came to evaluating his arguments to the conclusion that the virus originated in a natural way. And Thomas Vahlenkamp, director of the Institute of Molecular Biology at the Friedrich Loeffler Institute, said, "we can completely rule out the emergence of the virus in the laboratory. But I think it is highly unlikely to impossible. "

Healthier in freedom: factory farming weakens pigs

It could very well be a precursor of the virus have developed in a pig population and there for a long time had remained undetected. From animals in South America and Southeast Asia, for example, never viruses were isolated. Scientists estimate that is extremely suitable for intensive farming, the emergence of new virus strains. The pigs are crowded together in a confined space and not just stick it easier. Her immune system is weakened by the poor living conditions.

The first person became infected in April in Mexico with the new flu virus. Since then, the pathogen spreads throughout the world, in Europe doubled the number of deaths every two weeks. On Tuesday died in Germany for the first time a girl in the swine flu, which exhibited no pre-existing conditions. Vaccinations should have contained the spread of the virus. But the production of the vaccine does not run like fail: In Canada, the pharmaceutical company had to recall a load of GlaxoSmithKline vaccine because it triggered unusually large number of patients with allergic reactions.
