The sequencing of the deadly new variety was carried out in April at the Beijing Genomics Institute, the world's largest. German scientists had been scrambling to identify the virus. The Chinese, using samples provided by researchers working in Germany, cracked the code in three days.
*Thanks to John for the correction. He seems to be correct, although "e coli virus" (in quotes) gets 133,000 Google hits, many from sources you would think ought to know ("e coli bacteria" gets 807,000). A possible source of the confusion may be that it's a virus--a bacteriophage--that turns normally harmless E.coli into a killer.
