Anonymous users2024-01-24Escherichia coli is pathogenic and non-pathogenic. Non-pathogenic E. coli is a normal intestinal flora, while pathogenic E. coli can cause food poisoning.
Pathogenic E. coli is divided into two categories: invasive and toxin. The diarrhea caused by the former is similar to that caused by dysentery bacilli and is generally called acute dysentery. The diarrhea caused by the latter is gastroenteritis type, which is generally called acute gastroenteritis type.
The enterotoxins produced by toxin E. coli can be divided into heat-resistant toxins and heat-resistant toxins. The former is heated to 100 minutes and is not destroyed after 30 minutes, while the latter is heated to 60 minutes and destroyed after only 1 minute.
When soil and water are contaminated with feces, they can carry pathogenic E. coli, and infants are susceptible to infection. Infected foods can cause food poisoning due to incomplete heating, or cross-contamination and post-cooking contamination due to raw posture.
