Study Notes
Summary of Bacterial Pathogens
- Yersinia pestis is the causative agent of bubonic and pneumonic plague, with mortality rates nearing 100%.
- Vibrio cholerae is a gram-negative rod that causes severe gastroenteritis, particularly in areas with contaminated water or improperly prepared food.
- Pseudomonas aeruginosa is an opportunistic pathogen commonly found in hospital environments, causing infections in burn wounds and respiratory tracts.
- Campylobacter jejuni is the most common cause of gastroenteritis worldwide, with self-limiting symptoms that resolve in 3-6 days.
- Leptospira is a zoonotic bacteria that causes leptospirosis in humans, transmitted through contact with infected animal urine.
- Borrelia burgdorferi is the etiologic agent of Lyme disease, transmitted through the bite of Ixodes ticks.
- Treponema pallidum is the causative agent of syphilis, primarily transmitted through direct contact with an individual with an active syphilitic lesion.
- Mycoplasma pneumoniae is a bacteria that causes primary atypical pneumonia, commonly known as "walking pneumonia."
- Mycoplasma hominis is an opportunistic pathogen that causes urogenital tract diseases.
- Rickettsia species are obligate intracellular pathogens that spread through arthropod vectors.
- Rickettsia rickettsii causes Rocky Mountain Spotted Fever, with severe symptoms and a mortality rate of 20% if left untreated.
- Rickettsia typhi causes endemic typhus transmitted by rat fleas, while epidemic louse-borne typhus is caused by another Rickettsia species.
