摘要
PulseNet is a national network of pubic health and food regulatory laboratories established in the US to detect clusters of foodborne disease and respond quickly to foodborne outbreak investigations. PulseNet laboratories: currently subtype Escherichia coli O157:H7, non-typhoidal Salmonella. and Shigella isolates by a highly standardized I-day pulsed-field gel electrophoresis (PFGE). and exchange normalized DNA "fingerprint" patterns via the Internet. We describe a standardized molecular subtyping protocol for subtyping Listeria monocytogenes that was recently added to PulseNet. The subtyping can be completed within 30 h from the time a pure culture of the bacteria is obtained. (C) 2001 Elsevier science B.V. All rights reserved.
