Number of existing cases
Reservoir of Infection
Natural habitat of microbe
Zoonoses
Diseases of animals transmitted to humans

Direct contact between peoples
Vertical Transmission
Parents pass onto progeny; between a woman and fetus/infant via breastmilk
Fomite
Touching inanimate objects; indirect contact
Vectors

MIC
Minimum inhibitory concentration of an antimicrobial drug
Therapeutic Index
toxicity of a given drug; low = more toxic to patient, high = less toxic to patient
Bacteriostatic
Inhibit bacterial growth; host defenses eliminate remaining pathogens
Bactericidal
Kill bacteria
Broad Spectrum
Antimicrobials affect a wide range of bacteria, good for immediate therapy; good for GP and GN organisms
Narrow Spectrum
Antimicrobials affect a limited range of bacteria; less disruption of normal microbiota, but takes time to develop
Intrinsic/Innate Resistance
Types of bacteria inherently resistant to effects of a drug
Acquired Resistance
Sensitive organisms develop resistance via spontaneous mutation or acquiring new genetic information
Antigenic Drift
Minor mutations
Antigenic Shift
Genetic reassortment, dramatically different strains than original
