Bacterial Pathogenesis, Immunology, and Healthcare Quality Management

Comprehensive vocabulary flashcards covering bacterial and viral pathogenesis, HIV life cycles, immunology concepts, infection control principles, and healthcare quality management (5S-Kaizen-TQM).

Pathogenicity

The ability of a microbial agent to cause disease.

Virulence

The degree to which an organism is pathogenic or the ability of a microorganism to cause disease in its host.

Commensals/normal flora

Harmless and beneficial microorganisms under normal conditions often found in sites like the skin, mouth, and gastrointestinal tract.

Opportunistic pathogens

Microorganisms that usually do not cause disease in immunocompetent people but cause disease in situations that compromise host defenses.

Primary pathogen

An agent that causes disease in a host regardless of the host’s resident microbiota or immune system.

Virulence factors

Molecules such as toxins or enzymes like hyaluronidase and coagulase that contribute to a pathogen's ability to cause disease.

Invasion

A step in pathogenesis involving the dissemination of a pathogen throughout local tissues or the body.

Tropism

The ability of a virus to mount a successful infection of particular cells (cellular), tissue (tissue), or host species (host).

Virus shedding

The cellular release of virus particles into circulation.

Reverse Transcription (HIV Life Cycle)

The process where HIV RNA is converted into DNA using the enzyme reverse transcriptase.

Integration (HIV Life Cycle)

The stage where the integrase enzyme allows HIV DNA to be integrated into the host DNA.

Budding (HIV Life Cycle)

The final stage where immature HIV is pushed out of the cell and proteases activate it into mature infectious HIV.

AIDS

The last HIV stage characterized by a severely impaired immune system and a CD4 count under $200\,\text{cells per cubic millimeter}$ of blood.

Positive pressure personnel suits (PPPS)

Specialized, totally encapsulating protective garments used in BSL-4 labs that are constantly inflated by a supplied air source.

Antimicrobial Stewardship

The careful use of antibiotics and other antimicrobial agents to prevent the development of multi-antimicrobial-resistant organisms (MAROs).

Aseptic Technique

The practice of preventing contamination during medical procedures using sterile equipment and maintaining a clean environment.

Epitope

The specific site on an antigen that binds to an antibody or a T cell.

Alloantigens

Antigens found in different members of the same species, such as blood group antigens.

Haptens

Smaller protein substances that can generate immune responses if chemically coupled to a larger carrier protein like bovine serum albumin (BSA).

Antigenic Drift

Small changes or mutations in the genes of microorganisms that lead to changes in surface proteins.

Mutualism

A symbiotic relationship where both involved organisms benefit from each other.

Phagocytosis

A process of endocytosis in which a living cell engulfs or ingests other cells or materials for degradation.

Opsonization

An immune process which tags foreign pathogens for elimination by phagocytes.

Paratope

The specific binding site on an antibody that recognizes an antigen epitope.

Immunoglobulin G (IgG)

The main blood antibody ($80\%$ of total serum antibody) that neutralizes toxins and assists in opsonization.

Agglutination

The clumping of small particles, such as bacteria, through the help of antibodies like IgM.

MHC class II molecules

Molecules found on the surface of antigen-presenting cells (APCs) that present antigens to $CD4^+$ T helper cells.

Hypersensitivity reactions

Disorders caused by pathologic immune responses, categorized into Types I, II, III, and IV.

5S-Kaizen-TQM

A structured quality improvement framework in nursing care that includes sorting, continuous improvement, and total quality management.

Sort (Seiri)

The 5S activity of identifying and removing unwanted or unnecessary items from the workplace to reduce clutter.

Kaizen

A Japanese word meaning "continuous improvement," focusing on problem-solving with existing resources.

Quality Assurance

The means of providing confidence that the goals outlined in quality planning for a product or service will be fulfilled.

Quality Control

A system of maintaining standards by testing a sample of the output against specifications using tools like auditing and inspection.
