E ColiWhat is E Coli?E Coli is a pathogenic bacterium that can be found in the intestines of warm-blooded animals and humans. It can help break down food in the intestines and allows for the absorption of vitamin K. Its full name is Escherichia Coli, and while many strains are harmless, some can cause food poisoning in humans by producing harmful chemicals. Structure of E Coli E Coli is a rod-shaped Gram-negative bacterium that has a cell membrane and cell wall that protect its DNA. On the outside of each E Coli cell are small tails called flagella. E Coli breathes anaerobically, which means it does not need oxygen to breathe (breathe). It feeds on undigested nutrients in the intestines of mammals, including humans and ruminants such as cows, sheep and goats. How E Coli moves E Coli use little "tails" called flagella to travel and they spin counterclockwise, which causes them to move randomly. They move more when they are near food and both fall and swim across the body. They excrete toxic enzymes that help break down food molecules from the cell wall so they can penetrate it ...
