Title: E. Coli Bacteria, Illustration
Caption: Computer artwork of Escherichia coli bacteria. E. coli is a rod-shaped bacterium (bacillus). Its cell membrane is covered in fine filaments call pili or fimbriae. Hair-like structures called flagella at the rear of each bacterium provide propulsion to make it move. E. coli is a normal component of the intestinal bacterial flora, but under certain conditions some strains can cause severe infections like gastroenteritis.
