- Pili/Fimbriae: help attach the cell to surfaces
- Endotoxins
- Capsule (resists phagocytosis)
What do the Neisserias have in common?
- Virulence is pili/fimbriae and endotoxins
- Neisseria gonorrheae
- Neisseria meningitidis (and capsule)
Salmonella typhi Diseases
Enteric Bacilli
Typhoid Fever of the alimentary canal (GI Tract): Fever, diarrhea, nausea, severe headache, loss of appetite
Salmonella typhi Virulence
Enteric Bacilli
- Capsule (resists phagocytosis)

Shigella dysenteriae Virulence
Enteric Bacilli
Toxins (Shigella toxin)
Echerichia coli Diseases
Enteric Bacilli

- Traveler’s Diarrhea
- Infantile Diarrhea
- Hemorrhagic Colitis/ Hemorrhagic Uremic Syndrome (HUS)
- Bacillary Dysentery of the Alimentary canal
- Urinary Tract Infections
- Infections of the bladder, kidneys, ureters, and urethra
- Most significant opportunistic pathogen
- Most common pathogen to cause UTI’s
Echerichia coli Virulence
Enteric Bacilli
- Toxins (will cause GI disturbances)
- Pili/Fimbriae (aids in attachment)

Klebsiella pneumoniae Virulence
Enteric Bacilli
Capsule (resists phagocytosis)
Proteus mirabilis Diseases
Enteric Bacilli
- Secondary infection from burn wounds; bacterial colonies smell like “burned chocolate”
- Gastroenteritis: inflammation of the GI tract
- Urinary Tract Infections
- Can also cause UTS, ear and wound infections, especially in burn victims
Proteus mirabilis Virulence
Enteric Bacilli
- Pili (aids in attachment)
- Flagella
- enzyme urease (turns urea into ammonia which is too alkaline)
Pseudomonas aeruginosa Diseases
Enteric Bacilli
- Burn Wound Infections
- Urinary Tract Infections
- Gastroenteritis
- Pneumonia
- Ear Infections
- Produces blue-green pus
Pseudomonas aeruginosa Virulence
Enteric Bacilli
- Pili (aids in attachment)

Bordatella pertussis Diseases
Small Gram-Negative Bacilli
- Whooping Cough/Pertussis: Convulsive, painful coughing
Stage 1: Incubation Stage: no outward symptoms
Stage 2: Catarrhal Stage: Common cold-like symptoms
Stage 3:Paroxysmal Stage: Spasmodic or convulsive coughing; ciliary escalator in lungs stop; peak of the disease
Stage 4: Convalescent Stage: Recovery
Bordetella pertussis Virulence
Small Gram-Negative Bacilli
- Capsule (resists phagocytosis)
