  1. MRSA is a normal inhabitant of...
    skin and/or nose of healthy people and animals.
  2. Who is MRSA a major risk to?
    severe infection or death in immunocompromised hosts; no detrimental risks to immunocompetent hosts
  3. What component of MRSA make it resistant, and to what is it resistant?
    mecA gene altered penicillin-binding protein (PBP2a); resistant to all β-lactam antimicrobial agents
  4. What species of Staph carry the mecA gene? (3)
    MRS. aureus, MRS. pseudointermedius, MRS. schleiferi subspecies coagulans
  5. MRSA is the second most commonly reported agent associated with outbreaks of _____________, and it is the second most common ____________.
    nosocomial infections; zoonotic pathogen
  6. Risks for contracting MRSA. (3)
    nosocomial infection, occupational risk (health care personnel, veterinarians), public health
  7. How is small animal practice associated with increased risk for contraction of MRSA?
    it is assumed that mRSA is circulating in the small animal populations and veterinary personnel are getting exposed
  8. In the study conducted at OSU VMC, dogs owned by __________ were 20 times more likely to be MRSA positive.
    veterinary students

    SCCmec type II/ USA100
  10. What was the predominant strain of MRSA isolated from surfaces in the OSU VMC Equine hospital?
    SCCmec type IV/ USA500 => CA-MRSA
  11. Transmission of MRSA. (2)
    direct contact (esp. via hands), nosocomial transmission
  12. Prevention of MRSA infections. (7)
    CLEAN YOUR HANDS***, cover wounds, don't let animals lick your wounds, recognize early signs of MRSA infections, educate owners, no nose-to-nose contact with pets (to protect animal), isolate confirmed or suspect MRSA+ animals in the hospital
  13. ____________ is associated with a 4-fold increase in the risk of MRSA infection.
    Colonization with MRSA
  14. Early signs/risks of MRSA infections. (3)
    MRSA is present in 20% of dog bites and 4% of cat bites, skin infections with small red bumps resembling pimples, small abscesses

    opportunistic; does not usually
  16. __________ are the main source of MRSA in pets.
  17. Treatment of MRSA.
    boils/abscesses may be drained, antibiotics based on antimicrobial susceptibility profile of the organism
