Chapter 1 Microbiology Test Review Flashcards

Vocabulary flashcards covering key terms, areas of study, bacterial shapes, nutritional types, and concepts for the Chapter 1 Microbiology Test.

Gram Stain

A laboratory technique used for the identification of bacteria based on color results, where purple or pink indicate specific bacterial cell wall characteristics.

Biotechnology

An area of study in microbiology involving the practical application of biological systems and organisms to technical and industrial processes.

Epidemiology

An area of study in microbiology that focuses on the distribution, cause, and control of diseases in populations.

Immunology

An area of study in microbiology dedicated to understanding the immune system and host defenses against infectious agents.

Serology

An area of study in microbiology that examines blood serum and antigen-antibody reactions.

Bioremediation

An area of study in microbiology involving the use of microorganisms to clean up or degrade environmental pollutants.

Chemotherapy

An area of study in microbiology focusing on the treatment of disease using chemical substances or therapeutic drugs.

Genetic Engineering

An area of study in microbiology involving the direct manipulation of an organism's genes for practical or scientific purposes.

Etiology

An area of study in microbiology concerned with determining the cause or origin of a disease.

Microbial Genetics

An area of study in microbiology focused on the mechanisms of genetic inheritance and expression in microorganisms.

Colony

A visible mass or cluster of microorganisms growing on a solid medium, originating from a single cell or organism.

Habitat

The natural environment or specific physical location in which a microorganism normally lives and thrives.

Biofilm

A structured, surface-attached community of microorganisms embedded within a self-produced matrix.

Bacterium

A single-celled microscopic prokaryotic organism studied in microbiology.

Germ

A broad, non-technical term for a microscopic organism, particularly one capable of causing disease.

Virus

A microscopic infectious agent that requires a host cell to replicate.

Pathogen

Any disease-causing microorganism or biological agent.

Abiogenesis

The concept or hypothesis that living organisms can arise spontaneously from non-living matter.

Metabolism

The sum of all chemical processes and energy transformations occurring within a living organism.

Fermentation

An enzymatic, metabolic process by which microorganisms convert sugars into acids, gases, or alcohol.

Cocci

A term referring to spherical or round bacterial cells.

Bacilli

A term referring to rod-shaped bacterial cells.

Spirilla

A term referring to spiral or corkscrew-shaped bacterial cells.

Autotrophs

Organisms that synthesize their own food using inorganic carbon sources like carbon dioxide.

Heterotrophs

Organisms that derive energy and carbon by consuming organic compounds produced by other organisms.

Chemotrophs

Organisms that obtain energy through the chemical oxidation of organic or inorganic compounds.

Flagella

Long, whip-like cellular appendages used primarily for bacterial locomotion.

Cilia

Short, hair-like projections on the cell surface involved in motility and fluid movement.

Archaea

A domain of single-celled prokaryotic microorganisms often found in extreme environments.

Koch's Postulates

A series of experimental steps used to establish a definitive causal link between a specific microorganism and a specific disease.

Scientific Method

A systematic, multi-step process involving observation, hypothesis formation, testing, and conclusion used to conduct scientific investigations.
