  1. Occurs when a microorganism is able to survive exposure to an antibiotic. This may occur by
    1)Spontaneous gene mutations, or 2) transferred between bacteria, commonly on plasmids?
    Antibiotic Resistance
  2. Occurs when a microorganisms is able to survive exposure to an antibiotic. This may occur by?
    1) Spontaneous gene mutations

    2)transferred bacteria commonly on plasmids
  3. -Appeared in US in 1981

    - Transmitted by touch and respiratory droplets.

    - Requires barrier protection when infected person in hospital

    - Has developed resistance to beta-antibiotics (all-ilans & cephalosporins)
    MRSA (Methicillin Resistant Staph Aureus)
  4. - Can be transmitted fairly easily.

    -Located to skin & surface tissue, such as boils.

    -Outbreaks reported in prison, among athletic teams, among military recruits, newborns in nurseries
    CA-MRSA Community Acquired MRSA
  5. -First appeared in Japan in 1996

    -Thickening of bacterial cell wall makes diffusion of vancomycin across more difficult
    VISA Vancomycin Intermediate Staph Aureus
  6. - First reported in US in 2002

    - As of 2010, the CDC reports there are several drugs that are effective in treatment of disease.

    - MRSA obtained genes from VRE (below) to become VRSA
    VRSA Vancomycin Resistant Staph Aureus
  7. - First reported in 1987

    - Transmitted by contact of contaminated surfaces or caregivers hands. Not transmitted by coughing or sneezing

    - Can be spread rapidly throughout hospital

    - Doesn't affect healthy people: affect people already sick or weakened.

    -Easily shares Vancomycin resistance genes with other bacteria!!!

    -According to the CDC, most ? cases occur in hospitals
    VRE Vancomycin Resistant Enterococcus Faecium
  8. - Klebsiella pneumonia and E.Coli are the major mambers of Enterobacteriaceae that can have carbapenams resistance enzymes

    - Carbapenams are generally the treatment of last resort for Enterobacteriancae infections (When all else has failed, Carpabenams are used; hold back on use unless absolutely necessary

    -Screening patients and communicating at patient transfers is very important, but not currently happening consistently

    - Healty people do not get CRE infections. Weak, immunocomprimied, and recovering patients are vulnerable
    CRE Carbapenam Resistant Enterobacterianceae
