Escherichia coli bacterium. Coloured freeze- fracture transmission electron micrograph of an Escherichia coli bacterium (blue). E. coli is a gram-negative bacterium which is a normal inhabitant of human and animal intestines,where it helps to break down food. E. coli and other intestinal bacteria sometimes increase their numbers and cause infections such as gastroenteritis. The freeze-fracturing technique involves freezing the sample rapidly and then fracturing it with a knife. Magnification: x14,300 at 35mm size. Mag:X107,300 (at 10x8 size) size) | |
