H1N1流感病毒肆逆全球,但是,它长得什么样是大多数人们所不了解的。以下为美国疾控中心(CDC)所发表的透射电镜照片。

An electron microscope image shows an A H1N1 "swine flu" virus culture obtained from a California patient suffering from the current international flu outbreak, in an image obtained from the U.S. Centers for Disease Control (CDC) in Atlanta, April 28, 2009. New swine flu infections were found around the world on Tuesday and the specter of a pandemic began to hit the travel industry as governments warned people to stay away from Mexico where 149 people have died

this preliminary negative stained transmission electron micrograph (tem) depicts some of the ultrastructural morphology of an h1n1 "swine flu" virus culture obtained from a california patient suffering from the current international flu outbreak, in an image obtained from the u.s. centers for disease control (cdc) in atlanta april 28, 2009. new swine flu infections were found around the world on tuesday and the specter of a pandemic began to hit the travel industry as governments warned people to stay away from mexico where 149 people have died.

this handout photo courtesy of the centers for disease control and prevention shows a negative stained transmission electron micrograph (tem) recreation of the 1918 influenza virions that were collected from supernatants of 1918-infected madin-darby canine kidney (mdck) cells cultures 18 hours after infection. to separate these virions, the mdck cells are spun down (centrifugation), and the 1918 virus in the fluid is immediately fixed for negative staining. the solid mass in lower center contains mdck cell debris that did not spin down during the procedure. dr. terrence tumpey, one of the organization?s staff microbiologists and a member of the national center for infectious diseases (ncid), recreated the 1918 influenza virus in order to identify the characteristics that made this organism such a deadly pathogen. the united states has enough anti-viral drugs to combat a spreading outbreak of swine flu, the centers for disease control and prevention said april 30, 2009. acting cdc director richard besser said federal stockpiles of drugs and medical supplies had now reached nine states, and all affected states would get the medication by may 3.

this negative-stained transmission electron micrograph (tem) image depicts the ultrastructural details of a number of influenza virus particles, or ?virions? in a 2001 image released by the u.s. centers for disease control (cdc) on april 24, 2009. a deadly strain of flu never seen before has killed as many as 61 people in mexico and has spread into the united states, where several people were reported ill.

dr. terrence tumpey, a u.s. centers for disease control microbiologist for the national center for infectious diseases, examines specimens of the 1918 pandemic influenza virus, a virus that he reconstructed to identify and research the characteristics that made it so harmful in this 2005 handout photo acquired from the cdc on april 24, 2009. this effort enables researchers to develop new vaccines and treatments for future pandemic influenza viruses. the 1918 flu epidemic was caused by an influenza a virus (h1n1), a virus similar "swine flu," that killed more than 650,000 people in the united states, and up to 40-100 million people globally.

编者后记:自5月6日以后,美国逐步成为H1N1流感的高发地区,但是,有关美国猪流感的新闻报道及新闻照片越来越少。为什么???
