Flashcards

Reservoir (Microbiology)

A place where microorganisms live and multiply, such as the human genitalia, nasopharynx, or Peyer's patches of the small intestines.

Reservoir (Viruses)

A living organism that viruses need to multiply in. Humans, animals, or insects can be viral reservoirs.

Portal of Exit

The path microorganisms take to leave the reservoir and enter a new host. This can be through respiratory secretions, bodily fluids, or contaminated objects.

Portal of Entry

The way an organism or virus enters a new host. This can be through the respiratory system, digestive system, or skin.

Study Notes

Communicable Diseases

  • Diseases caused by pathogenic microorganisms that can be transmitted from an infected person to a susceptible person.
  • These are transmitted by direct contact, indirect means, or through breaks in skin integrity.

Infectious Diseases

  • Diseases where a living microorganism is present in the body.
  • Transmission does not always require contact between people.

Contagious Diseases

  • Diseases that are easily transmitted from person to person.
  • All contagious diseases are infectious, but not all infectious diseases are contagious.

Modes of Transmission

  • Direct: Person-to-person, most commonly through droplet transmission.
    • Examples: kissing, sexual contact
  • Indirect: Transmission through an intermediary object.
    • Examples: Vehicle-borne (non-living objects like catheters), Vector-borne (living things like insects)
  • Break in skin: Inoculation (contaminated needles/sharps), animal bites
  • Airborne: Microorganisms suspended in air; travel limited to a few feet.

Epidemiological Triad

  • Three factors for a disease to occur: host, agent, environment.
  • Host susceptibility is a factor in infection.

Types of Hosts

  • Patient: Infected person showing signs and symptoms.
  • Carrier: Harbors microorganisms but shows no signs or symptoms.
  • Suspect: Individual showing symptoms that may indicate a specific infection.

Horizontal Transmission

  • Transfer of microorganisms in a horizontal position.

Vertical Transmission

  • Transfer from a parent to offspring.
    • Example: Infected mother to newborn.

Other Concepts

  • Virulence: The strength and power of the microorganisms to cause an infection.
  • Pathogenicity: The capacity of microorganisms to cause an infection.
