Study Notes
Enterobacteria and Related Pathogens
- Typhoid fever caused by Salmonella enterica serotype Typhi and Paratyphi; can be prevented by proper cooking and vaccination
- Typhoid Mary, an asymptomatic carrier, infected many people and was quarantined for nearly three decades
- Shigella spp. cause inflammatory diarrhea and are treated with fluid replacement; antibiotics are avoided due to resistance
- Klebsiellae, including Klebsiella pneumoniae, can cause severe pneumonia and urinary tract infections, especially in hospitalized patients
- Enterobacter spp. and Serratia spp. can also cause nosocomial urinary tract infections
- Pseudomonas spp., including Pseudomonas aeruginosa, are common in the environment and can cause nosocomial infections, especially in burns patients
- Enterobacteria are not associated with periodontal infections, are Gram-negative, and are found in the oral cavity of up to 25% of the population
- Klebsiella pneumoniae has a polysaccharide capsule
- Pseudomonas aeruginosa is an important agent of nosocomial infections, resistant to most antimicrobial agents, and produces extracellular slime that resists phagocytosis
- Yersinia pestis causes plague, while Vibrio cholerae causes life-threatening watery diarrhea; both have distinctive morphological features
- Vibrio cholerae secretes an enterotoxin, causing rapid onset of symptoms
- Treatment and prevention of V. cholerae infection involves fluid and electrolyte replacement, oral rehydration therapy, and tetracycline if necessary
