[0001] This utility model relates to the field of microbial detection equipment technology, and in particular to a Shiga toxin-producing Escherichia coli enrichment culture device. Background Technology
[0002] Shiga toxin-producing Escherichia coli is an important foodborne pathogen that can cause serious illnesses in humans, such as diarrhea and hemorrhagic colitis, and even life-threatening complications like hemolytic uremic syndrome. When detecting Shiga toxin-producing Escherichia coli in food and water samples, it is necessary to first enrich the samples to increase the concentration of the target bacteria, facilitating subsequent isolation and identification. To provide suitable temperature conditions for bacterial growth and improve the efficiency and quality of enrichment culture, heating wires are typically installed in the incubator.
[0003] Since the culture vessel does not have a temperature loss alarm structure, if the heating equipment malfunctions and the relevant personnel are not informed in time, it will lead to abnormal temperature inside the culture vessel, thereby reducing the quality and efficiency of cultivation. In view of the above reasons, this application proposes a Shiga toxin-producing Escherichia coli enrichment culture vessel. Summary of the Invention
