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.
