2021: Development of Commodity Specific Molecular Salmonella Serotype Discrimination Panels


Salmonella bacterial infections, primarily from poultry products, cause as many as 131.6 million cases worldwide each year and upwards of 302,000 deaths. In the United States, Salmonella infections are the lead foodborne pathogen and cost more than $4 billion annually.

This technology employs state-of-the-art Real-Time PCR which uses short pieces of single-stranded DNA synthetically manufactured to exact compliment known sequences of DNA uniquely specific to each Salmonella serotype. The specificity and sensitivity of this technology can distinguish between closely related serotypes from only a few contaminating Salmonella cells in a test sample. Different fluorescent dyes are utilized in Real-Time PCR so that detection of different Salmonella serotypes can be automated using sensitive optical readers and results can be obtained in a few hours.

Reference Number: 2021-041

Market Applications:

  • Food Production
  • Food Safety

Features, Benefits, and Advantages:

  • Highly selective and sensitive.
  • More cost-effective than whole-genome sequencing.
  • Results were obtained more rapidly.
  • Multiple serotypes can be detected simultaneously.
  • Intellectual Property: A U.S. Provisional Application # 63/271,919 was filed on Oct 26, 2021.

Development Stage: The technology is in later stages of development and expands on earlier work that created a Real-Time PCR-based rapid method to identify and detect five serotypes of Salmonella.
