minimum inhibitory concentration (MIC)
The lowest concentration of an antimicrobial agent that prevents growth in the dilution method of determining antibiotic sensitivity

spectrum of activity
Refers to the range of different microbes against which an antimicrobial agent is effective
Gram-positive, filamentous, sporing, soil-dwelling bacteria; producer of many antibiotics
An antibacterial agent that blocks protein synthesis
(also called sulfa drug) A synthetic, bacteriostatic agent that blocks the synthesis of folic acid
A secondary infection from the removal of normal microbiota, allowing colonization by pathogenic, and often antibiotic-resistant, microbes
Referring to an inhibitory effect produced by two antibiotics working together that is greater than either can achieve alone
synthetic drug
An antimicrobial agent synthesized chemically in the laboratory
An antibacterial agent that inhibits protein synthesis
therapeutic dosage level
Level of drug dosage that successfully eliminates a pathogenic organism if maintained over a period of time
toxic dosage level
Amount of a drug necessary to cause host damage
An antibacterial agent that disrupts cell membranes
zone of inhibition
A clear area that appears on agar in the disk diffusion method, indicating where the agent has inhibited growth of the organism
