Understanding Methicillin-Resistant Staphylococcus pseudintermedius (MRSP) in Dogs: Symptoms, Risks & Treatments
Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is a growing concern in veterinary dermatology. Similar to the more well-known MRSA in humans, MRSP is a type of bacteria that has developed resistance to commonly used antibiotics, making infections more difficult to treat.
What is MRSP?
Staphylococcus pseudintermedius is a bacteria commonly found on the skin of healthy dogs. However, when there is underlying disease present such as an allergy, these bacteria can overgrow and cause infection. MRSP is a drug-resistant strain of these bacteria.
Symptoms and Risks
Signs of an MRSP infection often resemble a typical bacterial skin infection but may persist despite treatment. These can include:
- Red, inflamed skin
- Pustules or pimples
- Hair loss
- Crusting or scaling
- Itching or discomfort
How is MRSP Treated?
Because MRSP is resistant to many common antibiotics, culture and sensitivity testing is critical. This allows veterinarians to determine which specific antibiotics may still be effective. In many cases, topical therapy becomes the cornerstone of treatment. This may include antiseptic shampoos and conditioners that can help manage infection on the skin’s surface and minimise reliance on systemic antibiotics.
Dermcare Products That May Help
Resistance to high concentrations of antiseptics and antimicrobials in topical products is very uncommon. There is good evidence for the use of shampoos containing 2-3% chlorhexidine for MRSP infections. Dermcare have two medicated products in our range:
- Malaseb® Medicated Shampoo – Contains 2% chlorhexidine and 2% miconazole, providing antifungal and antibacterial action.
- Pyohex® Medicated Shampoo and Pyohex® Medicated Conditioner – Specifically formulated with 3% chlorhexidine which is ideal for dogs with superficial pyoderma.
A Multi-Pronged Approach
Combating MRSP requires more than just treatment, it involves managing the underlying skin condition, improving the skin barrier, and practicing good hygiene. Regular bathing with antiseptic shampoos, using topical treatments as directed, and working closely with your vet can make a significant difference in outcomes.
Always consult your veterinarian if your dog shows signs of skin infection or if a previous infection returns. Early diagnosis and targeted treatment are key to managing MRSP effectively.
