Study Notes
Taxonomic Classification of E. coli
- Domain: Bacteria - Includes all prokaryotic organisms, forming one of the three primary domains of life.
- Phylum: Proteobacteria - A major phylum known for its diverse metabolism and includes many pathogens.
- Class: Gamma-proteobacteria - A class within Proteobacteria, containing many of the most common bacteria found in clinical settings.
- Order: Enterobacteriales - An order comprising various gram-negative bacteria, commonly found in the intestinal tracts of humans and animals.
- Family: Enterobacteriaceae - A large family of bacteria that includes many important pathogens, as well as harmless flora in the gut.
- Genus: Escherichia - A genus within Enterobacteriaceae, known for species that are part of the normal gut microbiota and well-studied for their role in health and disease.
- Species: coli - Specific species under genus Escherichia, primarily found in the intestines of humans and animals, some strains can be pathogenic.
- Strain: DH5-alpha - A lac mutant strain of E. coli, commonly used in laboratories for cloning and molecular biology experiments.
- E. coli O157-H7: A harmful strain linked to serious foodborne illness; produces a toxin that contributes to interhemorrhagic disease, characterized by bloody stools. Its pathogenicity is due to specific genes that allow toxin production, absent in benign strains.
