E. coli is an important model organism found in high school biology. Many aspects of knowledge are involved, such as the basic structure and division of

prokaryotes, experiment of T2 'bacteriophage infection, common carriers of genetic engineering, identification of Escherichia coli, and regulation of microbial enzyme synthesis.

       Escherichia coli was first discovered in 1885. For a long time, it was considered part of the normal gut flora and was considered a nonpathogenic bacterium. It

was not until the mid-20th century that specific serotypes of E. coli were recognized as pathogenic to humans and animals, particularly infants and young birds,

often causing severe diarrhea and septicemia. According to different biological characteristics, pathogenic EScherichia coli can be divided into five categories:

pathogenic EScherichia coli (EPEC), enterotoxigenic Escherichia coli (ETEC), enterohemorrhagic Escherichia coli (EHEC), enteroinvasive escherichia coli (EIEC), and

enteroadhesive escherichia coli (EAEC).

          And how should we kill e. coli? E. coli can be killed in several ways, such as visiting a doctor or using ultraviolet light to kill E. coli.

          E. coli is a gram-negative bacterium. It is in the decline of human immunity, erosion of the human body, causing abdominal pain, diarrhea, fever and other

clinical symptoms, we usually pay attention to personal hygiene, this is very important. Tableware disinfection can choose disinfectant solution or disinfection

cabinet to achieve the effect of killing Escherichia coli.  

           On ordinary days we should keep enough sleep and had better not work overtime. Also can use boiling water soak, still have steam disinfect, oven disinfect

and so on are ok. I would like to recommend the use of ultraviolet sterilization lamp to kill Escherichia coli, this method is not only safe but also very effective, our

Lightbest uv sterilization lamp, in the report issued by the Jiangsu Provincial Center for Disease Control and Prevention: The effective rate of killing Escherichia coli

is as high as 99.99%.
