Methicillin-Resistant Staphylococcus Pseudintermedius (MRSP) in Dogs and Cats

MRSP is a type of bacteria that is becoming increasingly common in dogs and cats, posing a serious threat to their health. Today, our Orange Park vets will explain MRSP in cats and dogs, treatment options, and prevention tips.

What is MRSP in dogs & cats?

MRSP is a type of bacteria that has developed resistance to some antibiotics, making it difficult to treat infections. The prevalence of MRSP in pets has been increasing in recent years, with some studies showing rates as high as 20% in some veterinary hospitals.

Pets with underlying health conditions, frequent antibiotic use, or prolonged hospital stays are at a higher risk of developing MRSP infections. Additionally, close contact with other infected animals or contaminated environments can also increase the likelihood of transmission. 

It is important for pet owners to work closely with their veterinarian to prevent and manage MRSP infections in order to protect the health of their furry companions.

What are the symptoms of MRSP in dogs & cats?

Some of the most common signs of MESP in cats and dogs include:

  • Skin infections, including abscesses and pustules
  • Hair loss or thinning in affected areas
  • Itching and scratching
  • Swelling or redness around the infected area
  • Fever or lethargy
  • Pain or discomfort when touched

In severe cases, MRSP infections can lead to systemic illness, such as septicemia or pneumonia, requiring immediate veterinary attention and treatment. 

How can vets diagnose MRSP in dogs & cats?

A specialized laboratory must conduct a culture and sensitivity test to diagnose MRSP, and results could take up to 7 days. It is important to note that MRSP infections do not exhibit any distinct visual differences from other types of Staph infections. 

How is MRSP in cats & dogs treated?

Treatment for MRSP in dogs and cats typically involves a combination of oral antibiotics – there are some antibiotics MRSP is not resistant to – chosen based on culture and sensitivity results, as well as local treatment of the infection site.

Oral antibiotics are commonly used to target the bacteria causing the infection. These medications are usually prescribed for several weeks to ensure complete eradication of the MRSP.

In addition to oral antibiotics, local treatment of the infection site is often necessary for effective management of MRSP infections. This may involve flushing a skin abscess, cleaning and disinfecting wounds, or using antibacterial shampoos to help reduce the bacterial load on the skin.

It is important to follow your veterinarian's instructions closely and complete the full course of treatment to prevent the recurrence of MRSP infections in your pet. With proper treatment, most MRSP infections can be successfully eradicated within weeks, leading to a full recovery for your furry friend.

How can I prevent MRSP in my cat or dog?

Unfortunately, there is no guaranteed way to prevent MRSP infections in pets, as the bacteria can be present in the environment. However, practicing good hygiene, keeping your pet's living area clean, and avoiding contact with other animals known to have MRSP can help reduce the risk of infection.
