micro; 1. Classification of Microbes and The Microbiome

These flashcards cover key terms and concepts related to the classification of microbes and the human microbiome as discussed in the lecture.

Microbiology

The study of microscopic organisms, including bacteria, viruses, fungi, and protozoa.

Symbiosis

An association between two or more species, which may encompass different relationships defined by their mutual effects on each other.

Colonization

Presence of microorganisms on a body surface without causing harm to the host.

Transitory microorganisms

Microbes that may live on the body temporarily or may come and go.

Infection

The invasion of body tissue by microorganisms, resulting in disease.

Phage Typing

Method used to identify bacteria based on susceptibility to specific bacteriophages.

Bacteriocins

Protein substances produced by bacteria that inhibit the growth of similar or closely related bacterial strains.

Antagonistic relationship

Relationship where both symbionts are harmed.

Eukaryotes

Cells that contain a nucleus and organelles, such as fungi and protozoa.

Genotype

The genetic makeup of an organism.

Phenotype

The observable physical characteristics of an organism.

C. difficile

A bacterium that can cause infection and is kept in check by healthy gut flora; may overgrow after antibiotic use.

Microbiome

The collective genomes of the microbes living inside and on the human body.

Antimicrobial stewardship

Efforts to promote the appropriate use of antimicrobials to combat antibiotic resistance.

Helminths

Parasitic worms, including nematodes, trematodes, and cestodes.

Pathogen

An organism that causes disease.

Homeostasis

The maintenance of stable internal conditions, which can be influenced by microbial presence.
