What are different factors that determine/influence the likelihood of infection of a microorganism
Virulence Numbers Host resistance Systemic level factors (e.g., antibodies) Local level factors
What are factors that influence the selection of antibiotic therapy?
Identification of the organism Susceptibility of the organism Site of infection Drug characteristics Pharmacodynamics Pharmacokinetics Patient factors Allergy Safety Cost Route of administration
What is the post-antibiotic effect?
Suppression of microbial growth even after levels of antibiotic have fallen below the MIC
Length of time following the removal of antimicrobial drug to reach log-phase growth
What are patient factors that could influence the selection of antibiotic therapy?
Immune system Renal function Hepatic function Poor perfusion Age Pregnancy/lactation
What is empiric therapy?
The initiation of treatment before a firm diagnosis is made (usually involves broad spectrum antibiotics)
What is directed therapy?
The choice of treatment is based on knowledge of the organism that is the cause of the infection
What are narrow spectrum antibiotics?
Anti-microbial agents acting on a limited group of microorganisms
What are extended spectrum antibiotics?
Effective against one class of organisms as well as a significant number in a different class
