Caption:
E. coli - Gram-negative, facultatively anaerobic, rod prokaryote; strains undergoing conjugation via a pilus. Bacterial conjugation is the ability to transfer DNA between strains of bacteria (via a pilus). It allows a new mutation to spread through an existing population. It is believed that this process led to the spread of toxin synthesis from Shigella to E. coli (O157:H7). E. coli can cause urinary tract infections, traveler's diarrhea, nosocomial infections, meningitis, peritonitis, mastitis, septicemia and gram-negative pneumonia.. It causes a variety of skin and wound infections such as scalded skin syndrome, scarlet fever, erysipelas and impetigo.
