Study Notes

Asepsis and Infection Control

  • Asepsis refers to the practice of eliminating disease-causing organisms to prevent infection.
  • Severe Acute Respiratory Syndrome (SARS) is a viral respiratory illness.

Pathogens and Infections

  • Pathogens are microorganisms that can cause disease in humans.
  • Sepsis indicates tissue poisoning resulting from infection.
  • Septicemia or bacteremia describes the spread of infection or its products through the bloodstream.
  • Infection indicates the presence of disease-causing microorganisms, while septic refers to a systemic inflammatory response from extensive tissue destruction.

Systemic Inflammatory Response

  • SIRS (Systemic Inflammatory Response Syndrome) is characterized by symptoms like high fever, rapid heartbeat, low blood pressure, and increased white blood cell count during a septic condition.

Infectious Diseases

  • An infectious disease arises from the invasion and reproduction of pathogens in a host.

Aseptic Techniques

  • Aseptic practices include the use of gloves, masks, gowns, hair covers, and patient isolation to prevent infection transmission.

Agents of Infection

  • The six primary infectious agents are bacteria, viruses, fungi, parasites, prions, and multi-drug resistant organisms (MDROs).

Bacteria Characteristics

  • Bacteria are unicellular microorganisms capable of causing organ dysfunction through tissue invasion and inflammation.
  • They can be transmitted through air, food, water, soil, vectors, or sexual activity.
  • All bacteria can potentially impair organ function.

Exotoxins and Endotoxins

  • Examples of bacteria producing exotoxins include diphtheria, botulism, and tetanus.
  • Gram-negative bacteria such as Gonorrhea and meningococcal meningitis produce endotoxins found in their cell walls.

Viral Infections

  • Hepatitis and HIV are common viruses that can cause extensive tissue damage and chronic conditions.

Fungal Infections

  • Fungi are generally single-celled organisms categorized into molds and yeasts.
  • Candida albicans is part of normal human flora and can lead to infections in immunocompromised individuals.
  • Candida infections are considered opportunistic and are increasingly prevalent and lethal.
  • Fungal infections frequently occur in hair, skin, and nails.

Parasites

  • Parasites are primarily multicellular organisms, with examples including protozoa (thrive in water), helminths (tapeworms, hookworms, trichinae), and arthropods (mites, fleas, ticks) that can induce various diseases.

Prion Diseases

  • Prion diseases are also known as transmissible spongiform encephalopathies (TSEs) and are untreatable and always fatal in both humans and animals.
