Labs launching experiments with H7N9 samples supplied by China
A number of labs around the world have received samples of the H7N9 influenza virus and begun research in recent days to assess the virus' effects in animals and to develop diagnostics and vaccines, according to a ScienceInsider report yesterday. The World Health Organization (WHO) reported Apr 12 that the China Center for Disease Control and Prevention had sent samples to all five of the WHO's collaborating centers for flu, in Melbourne, Tokyo, London, Atlanta, and Memphis. The US and UK centers received their samples last week. At the US Centers for Disease Control and prevention (CDC), researchers working over the weekend inoculated the virus into hundreds of eggs, where it grew "very well," a spokesman said. CDC officials started sending samples to other labs on Apr 15. At the UK National Institute for Medical Research, researchers planned to infect ferrets with the virus to see how it affects them and to generate antibodies, which can be used to develop diagnostic tests and to find out if the antibodies cross-react with existing candidate vaccines for other H7 flu strains. Meanwhile in the Netherlands, virologist Ron Fouchier, PhD, also plans to infect ferrets to test whether the virus can spread between them via aerosols or tiny droplets. Also, he said he's interested in finding out which mutations might make it spread easily in ferrets—the type of research that sparked a major controversy when he reported it with H5N1.

Too many labs still have rinderpest samples, OIE chief says
Two years after the eradication of rinderpest, too many laboratories still are keeping samples of the devastating cattle virus, said Bernard Vallat, DVM, director-general of the World Organization for Animal Health (OIE). When rinderpest eradication was declared in 2011, OIE member countries promised to destroy their samples or pass them to a few high-security labs. But Vallat said 25 labs—which he didn't identify—still have samples of the virus, according to a Reuters report yesterday. "If you release these materials into the wild, they can touch sensitive species and re-trigger a global animal disease even more so that there are no animals vaccinated anymore," Vallat told Reuters. "It would be a disaster if it happened." Scientists say they need samples of the virus for research and to make vaccines in case of a bioterrorist attack with the pathogen, the story noted. Rinderpest and smallpox are the only diseases that have been eradicated.
