Single-tube detection of a foodborne bacterial pathogen using user-friendly portable device.

Timely and reliable detection of foodborne bacterial pathogen is crucial for reducing disease burden in low- and middle-income countries. However, laboratory-based methods are often inaccessibility in resource-limited settings. Here, we developed a single-tube assay and a low-cost palm-sized device for on-site detection of the representative foodborne bacterial pathogen, Salmonella Enteritidis.
