Salmonella Typhimurium Biofilm Detection on Food Surfaces

Data from a study comparing traditional and genomic methods for detecting Salmonella Typhimurium cells in egg biofilms during early formation. The research examined biofilm growth on stainless steel, silicone, and nylon surfaces over five hours at 37°C. It was produced by USDA Agricultural Research Service scientists.

Use Cases

• Analyze Salmonella cell attachment rates across stainless steel, silicone, and nylon surfaces to compare material susceptibility.
• Compare detection timelines between traditional plate counts and long-read whole genome sequencing methods for early biofilm identification.
• Model biofilm growth curves in liquid whole egg over a five-hour incubation period at 37°C.

Strengths

• Data compares three distinct food-contact surfaces: stainless steel, silicone, and nylon.
• Includes measurements from the first five hours of biofilm incubation, capturing early formation stages.
• Compares traditional microbiological methods with innovative long-read whole genome sequencing.

Limitations

• Specific sample sizes, row counts, and columnar data structure are not provided in the input.
• Data scope is limited to Salmonella Typhimurium in liquid whole egg under controlled lab conditions.
• Geographic origin of the samples or broader environmental applicability is not specified.
