susceptible than its counterparts to a specific antimicrobial compound (or combination thereof).

Asymptomatic infection: An infection where the patient does not have any apparent symptoms (also known as a subclinical infection).

ATP: Short for adenosine triphosphate, an organic compound that serves as a source of energy for many metabolic processes.

Bacteria: Microscopic, single-celled organisms that have some biochemical and structural features different from those of animal and plant cells.

Biocontrol: Method of controlling pests (including insects, mites, weeds, and diseases) in plants that relies on predation, parasitism, herbivory, or other natural mechanisms.

Biofilms: Bacterial communities that adhere to biotic or abiotic surfaces. These microorganisms are usually encased in an extracellular polysaccharide matrix that they themselves synthesize and may be found on essentially any environmental surface in which sufficient moisture is present.

Colonization: Capacity of a bacterium to remain at a particular site and multiply there.

Commensalism: Two (or more) species coexist, one deriving benefit from the relationship without harm or obvious benefit to the other.

Conidia: Asexually produced fungal spores, formed on a conidophore. Most conidia are dispersed by the wind and can endure extremes of cold, heat, and dryness. When conditions are favorable, they germinate and grow into structural parts of the body of a fungus (American Heritage Science Dictionary. 2011. Houghton Mifflin Harcourt Publishing Company).

DNA (deoxyribonucleic acid): Any of various nucleic acids that are usually the molecular basis of heredity are constructed of a double helix held together by hydrogen bonds between purine and pyrimidine bases which project inward from two chains containing alternate links of deoxyribose and phosphate, and that in eukaryotes are localized chiefly in cell nuclei.

Ecology: The scientific study of the relationship between living things and their environments.
