Study Notes
Enterobacteriaceae
- The Enterobacteriaceae family includes genera of enteric gram-negative rods that can cause both gastrointestinal and extra-intestinal diseases.
- The genera of enteric gram-negative rods that can cause both gastrointestinal and extra-intestinal diseases include Escherichia, Klebsiella, Proteus, Enterobacter, and Serratia.
Extra-intestinal Diseases
- The organism that is primarily extra-intestinal in causing diseases is Klebsiella.
- The genera of enteric gram-negative rods that primarily cause extra-intestinal diseases include Klebsiella and Serratia.
Transmission of GI Diseases
- Fecal contamination plays a significant role in the transmission of organisms causing GI diseases.
- The transmission of organisms causing GI diseases occurs mainly through the fecal-oral route.
Normal Flora and Pathogenicity
- Escherichia (E. coli) is part of the normal flora of the colon and can be pathogenic both within and outside of the GI tract.
Enterobacteriaceae Organisms
- Enterobacteriaceae organisms are typically found in the gastrointestinal tract, but can also be found in the environment and in water.
- Enterobacteriaceae organisms are gram-negative, rod-shaped, and facultative anaerobes.
