Bacteria are prokaryotic microorganisms that widely exist in nature and have the characteristics of small size, simple structure and strong environmental adaptability. Bacteria have many impacts on people's daily life and production. Various genetically engineered bacteria can be used in food production, pharmaceutical production and environmental purification. In addition, bacteria can cause food nutrient loss, flavor changes, and shelf-life spoilage. Most bacteria will not cause harm to people, but the existence of some serious pathogenic bacteria will threaten human life and health. Therefore, imaging analysis of bacterial structural and morphological changes and their growth status is of great significance for the treatment of diseases caused by bacterial infection. https://www.bioimagingtech...
