Can ultraviolet germicidal lamps kill E. coli?
How much do you know about "colony colonies"?
Large intestine colonies are one of the commonly used indicator bacteria for food contamination, causing the large intestine colonies in tableware to exceed the standard, mainly due to secondary pollution. If the tableware is not regularly disinfected in time, or the time and temperature are not reached when the tableware is sterilized by dry heat, and the personal hygiene of the staff is not up to the standard, the coliform flora will exceed the standard, which is easy to cause diarrhea and gastrointestinal infections.
The coliform group is not a bacteriological classification name, but a term in the field of sanitary bacteria. It does not represent a certain or a certain genus of bacteria, but refers to a group of bacteria with certain characteristics that are related to fecal pollution. These bacteria are in biochemical and serum The science is not completely consistent. It is defined as: aerobic and facultative anaerobic, Gram-negative non-bacterial bacteria that can decompose lactose and produce acid and gas at 37°C. The coliform group mainly includes Escherichia spp., Citrobacter spp., Murebsiella spp. and Enterobacter spp., all of which come from the intestines of humans and warm-blooded animals.
The Escherichia coli that we are familiar with is one of the colonies of large intestine.
The source of transmission of colonies in the large intestine. Colonies are mainly spread through food, water, and close contact. Take Escherichia coli as an example. Escherichia coli is a type of enteric bacilli and is a normal colony in the intestines of humans and animals. Escherichia coli often attaches to foods and surfaces along with host contaminants in the external environment. When foods are not subjected to effective high-temperature cooking or other sterilization methods before being eaten, they may enter the human intestines and stomach, causing diarrhea, gastrointestinal infections and other symptoms.
