PulseNet creates DNA fingerprints of bacteria isolated from ill persons using pulsed-field gel electrophoresis (PFGE).

Explanation:
PulseNet creates DNA fingerprints of bacteria isolated from ill persons using pulsed-field gel electrophoresis. The process generates standardized banding patterns for each isolate, which labs across the network compare to identify closely related strains. When patterns match, it suggests a potential link between cases and a common source, enabling outbreak detection and investigation. PFGE has been the traditional method for producing these fingerprints within PulseNet, forming the foundation for linking illnesses even as newer sequencing approaches are increasingly used.
