Response to medical condition activity In this task you will
should I add anything else 1. How could the CDC determine that the strains from the three states originated from the same source. To determine that bacterial strains from three states originated from the same source, the CDC engages in a multistep process involving close collaboration with regulatory partners such as the FDA, USDA-FSIS, and PulseNet scientists. This collective effort enables investigators to trace the source of outbreaks more efficiently, issue timely public alerts, and identify gaps in food safety systems that might otherwise go unnoticed (CDC). PulseNet, a CDC-coordinated network, uses Whole Genome Sequencing (WGS) and Pulsed-Field Gel Electrophoresis (PFGE) to analyze bacterial DNA fingerprints and identify infection clusters. WGS, which reveals the entire DNA composition of an organism, enhances our understanding of variations within and between species (FDA). These methods allow scientists to identify clusters of infections and trace outbreaks back to their source, even across different locations. WGS, due to its precise strain differentiation, has become the standard method for investigating foodborne outbreaks. Epidemiologists also gather patient data to link exposures with genetic findings, further substantiating a shared origin. The integration of these methods allows the CDC to present compelling evidence that bacterial strains from diverse locations have a shared source, thereby enhancing the effectiveness of public health responses (CDC).
