Stage 3:Paroxysmal Stage: Spasmodic or convulsive coughing; ciliary escalator in lungs stop; peak of the disease
Stage 4: Convalescent Stage: Recovery
Yersinia Pestis Diseases
- Bubonic Plague/Black Death: Infection of the lymphatic system; Lesions called BUBOS form
- Septicemic Plague: Infection in the blood stream
- Pneumonic Plague
Both the septicemic and pneumonic plagues can be secondary infections from the bubonic plague or be spread on their own
Klebsiella pneumoniae Diseases
- Lobar Pneumonia
- Hospital Acquired/ Nosocomial Pneumonia

- Hemorrhagic Colitis/ Hemorrhagic Uremic Syndrome (HUS)
- Bacillary Dysentery of the Alimentary canal
- Urinary Tract Infections
- Infections of the bladder, kidneys, ureters, and urethra
Proteus mirabilis Diseases
- Secondary infection from burn wounds; bacterial colonies smell like “BURNED CHOCOLATE”
- Gastroenteritis: inflammation of the GI tract
- Urinary Tract Infections
- Can also cause ear and wound infections, especially in burn victims
Pseudomonas aeruginosa Diseases
- Burn Wound Infections
- Urinary Tract Infections
- Gastroenteritis
- Pneumonia
- Ear Infections
Produces blue-green pus
Vibrio cholerae dieases
- Rice Water Stool: whitish color to feces
- Asiatic cholera
Treponema pallidum Diseases
-Exclusively found in humans
- Syphilis
- Acquired Syphilis: Received through direct sexual contact
- Congenital Syphilis: Infected pregnant woman passes infection to unborn child
- 4 Stages of Syphilis
- Primary Syphilis: Chancre sore form (small hard ulcers)
- Secondary Syphillis: Skin rashes form on the hands and feet
- Latent/Hidden: Symptoms disappear
- Tertiary Syphilis: Gummas form (rubber-like lesions); other severe symptoms including dementia, madness, tumors occur. People usually do not get to this stage because of modern medicine
Borrelia burgdorferi Diseases
Lyme Disease/ Lyme Borreliosis: Bull’s eye rash
Leptospira interrogans Diseases
- Leptospirosis/Infectious Jaundice: Biphasic (2-part)disease that starts with flu-like symptoms and later progresses into liver damage, and renal failure
- Weil’s Disease: Advanced case of severe liver and kidney damage
