Enteric
Pertaining to the intestine
Ferment
Extraction of energy through anaerobic degradation of substrates into similar, reduced metabolites=
Commensal
Species benefits from the host without hurting it
Mutualistic
Host and pathogen both benefit
Zoonotic
Infectious disease indigenous to animals that humans can acquire through direct or indirect contact with infected animals
Fomite

Indicator organism
In water analysis, any easily cultured bacteria that may be found in the intestine and can be used as as an indicator of fecal contamination
Broad spectrum
Drugs that have an effect on a wide variety of organisms
Narrow spectrum
Drugs that are selective and limited in their effects
Side effects
Unwanted effects of an antibiotic
Minimal inhibitory concentration
Smallest concentraion of a drug needed to inhibit/control growth
Minimal bactericidal concentration
Lowest level of a drug that completely kills
Resident flora
Deeper, more stable microbiota that inhibt the skin and exposed mucuous membranes
Transient flora
Bacteria that don’t usually reside there but may be preseident at a particular location
Epidermis
Outermost layer of skin
Glands
Synthesize and release substances such as sweat or sebum
Follicles
Enfolding of the skin that produces hair
Gardening would have more transient b/c
Soil dweling bacteria would include many endospores that effect our transient bacteria
