Susceptibility Testing, Aerobic and Facultatively Anaerobic Organisms
Also known as: Sensitivity Testing
Use
Determine antimicrobial susceptibility of organisms involved in infectious processes when the susceptibility of the organism cannot be predicted from its identity. The pattern of antibiotic susceptibility is sometimes used to monitor nosocomial infections such as methicillin-resistant Staphylococcus aureus and to evaluate or follow the development of resistance to new antimicrobial drugs.1,2
Special Instructions
Not provided.
Limitations
Interpretive criteria are not available for all bacteria. The categorization into susceptible, intermediate, and resistant is based on antibiotic levels in serum of individuals with normal kidney and liver function. Drugs concentrated in urine may treat urinary tract infections even if resistant per the categorical interpretation, and vice-versa for poorly vascularized areas even if interpreted as susceptible.
