Study Notes
Distinguishing Bacterial Infections from Normal Flora
- Bacteria need to be differentiated from normal flora present at the site of infection
- Normal flora may be contributing to the infection in some situations
Uncertainty in Bacterial Significance
- When unsure about the significance of a bacteria from a specimen, discuss with the attending physician
- Importance of clarifying the role of bacteria in infection
Mechanisms of Antibiotic Action
- Cell wall synthesis inhibition
- Cell membrane synthesis inhibition
- DNA replication inhibition
- RNA transcription inhibition
Antibiotic Resistance and Sensitivity
- Micro-organism growth indicates resistance to the drug
- Lack of growth indicates sensitivity to the drug
- Monitoring of growth or lack of growth to determine antibiotic effectiveness
Standardized Testing for Bacterial Susceptibility
- Table (1) only includes bacteria with standardized testing procedures available
- National Committee for Clinical Laboratory Standards outlines and recommends testing procedures
