Which typing pattern is used in triaging PulseNet clusters?

Explanation:
PFGE patterns provide a DNA fingerprint of bacterial isolates, allowing epidemiologists to quickly compare strains from different cases and identify potential outbreak clusters across jurisdictions. When isolates share an indistinguishable PFGE pattern, the cluster is flagged for further investigation as a possible outbreak; differing patterns suggest unrelated infections. The other options—blood type, height, and eye color—are human traits and do not reveal genetic relationships between pathogens, so they are not used for linking cases in PulseNet.
