The rise of methicillin-resistant Staphylococcus pseudintermedius (MRSP) in the canine population has raised questions about the safety of elective surgeries, particularly spays and neuters, in dogs carrying this antibiotic-resistant bacterium. We’re here to provide insights into this concern, emphasizing the importance of distinguishing between active infections and healthy carriers.
Active MRSP Infection: Hold Off
If a dog has an active MRSP infection, such as a skin infection, vets have suggested delaying elective surgeries if possible. Performing surgeries on animals with active infections, regardless of the pathogen involved, may increase the risk of surgical site infections due to the heightened overall burden of MRSP on the skin and other areas.
No Active Infection: Proceed with Caution
In the absence of an active infection, where the dog is a healthy carrier after recovering from a previous MRSP infection, some vets may lean towards proceeding with elective surgeries.
- Spay-associated infections are rare: Infections specifically linked to spaying procedures are uncommon.
- No prophylactic antibiotics for spays: Antibiotics are not typically used preventatively for low-risk procedures like spays. The appropriateness of antibiotic use is crucial, and their misuse should be avoided.
- Similar infection risk for MRSP and methicillin-susceptible S. pseudintermedius: MRSP is not inherently more likely to cause infections following spays than its methicillin-susceptible counterpart. The key difference lies in the increased resistance of MRSP when infections occur.
- Widespread presence of S. pseudintermedius: Methicillin-susceptible S. pseudintermedius is found on nearly all dogs. Given that infections are rare despite the ubiquitous presence of this bacterium, there should be no additional infection risk posed by the antibiotic-resistant MRSP version.
Surgical Antisepsis Practices Matter
Every dog carries various bacteria that could potentially cause infections. Vets often highlight the importance of employing rigorous surgical antisepsis practices, including clipping, scrubbing, the use of sterile instruments, and maintaining a proper operating room. These practices aim to prevent a critical number of bacteria from entering the sterile surgical site.
Unique Considerations for Other Surgeries
Vets have acknowledged that the presented strategy might not be universally applicable, especially in surgeries where prophylactic antibiotics are used, and staph bacteria are primary infection causes. In situations like orthopedic procedures, where MRSP infections are challenging to treat, addressing the implications of MRSP positivity in animals undergoing such surgeries requires further exploration.
A nuanced approach is required in balancing the risks and benefits associated with elective surgeries in dogs carrying MRSP.
