What class of drug usually causes allergic reactions?
Penicillin hyproducts
Healthcare acquired infections:
- Also known as?
- develop from?
- Nosocomial infection
- Infections from any health care
- How do biofilms promote infection?
- What types of microbes can they be composed of?
- Serve as reservoir
- Can be bacterial, fungal, or both
What interactions (3) cause healthcare acquired infections?
- Microbes in hospitals
- Compromised hosts in hospitals
- Transmission in hospitals
How do microbes in hospitals take advantage?
Most likely opportunistic microbes and drug resistant
What are the two types of compromised hosts in hosptials?
- Compromised physical barriers
- Burns, wounds, etc.
- Compromised immune system
- Drugs, immune cells
Community acquired infections typically infect:
Are resistant/susceptible to antibiotics?
- People with healthy immune systems.
- Susceptible
What are the ways HAIs can be transmitted?
- Direct contact (workers, contaminated medical device)
- Indirect (Fomite, air)
What are some things that raise the risks of HAIs?
- Implanted devices
- Surgery
- Injections
- Misuse of antibiotics
What are the 4 most common HAIs?

- Catheter
- Surgical site
- Ventilator
What type of microbe typically infect central lines?
Coagulase negative Staphylococci
What is the most common type of microbe associated with Catheters?
E. coli
What is the most common type of microbe associated with surgical sites?
Staph Aureus
What is the most common type of microbe associated with ventilators?
Pseudomonas Aeruginasa
