Should a dog with MRSP be spayed?

Posted in Dogs
This is an increasingly common question, as methicillin-resistant Staphylococcus pseudintermedius (MRSP – essentially the canine version of the high-profile human "superbug" MRSA) has expanded greatly in the canine population. As more dogs get MRSP infections and even more become inapparent carriers of this bug, more dogs that are carriers will need surgery (both elective and non-elective). … Continue Reading

Is MRSP in a dog a risk to the family?

Posted in Dogs
This is an increasingly common question, because MRSP is increasingly common. I’ve had two calls about it this week, and it’s only Wednesday. It’s a good question to ask because MRSP (methicillin-resistant Staphylococcus pseudintermedius) is a highly drug-resistant bacterium that causes a lot of problems in dogs, and because of the high profile of its… Continue Reading

MRSP infection in a person

Posted in Dogs
“Is MRSP zoonotic?” That’s a question I get all the time. MRSP (methicillin-resistant Staphylococcus pseudintermedius) is a canine staph (a bacterium) to which people are exposed all the time. Yes, it can infect people, but only very rarely, particularly when you consider how often they’re exposed. Nonetheless, human MRSP infections can occur. My typical answer… Continue Reading

MRSP transmission between people and pets

Posted in Cats
Today (like most days) I answered questions about the potential for transmission of methicillin-resistant Staphylococcus pseudintermedius (MRSP) between people and pets. We have a long way to go before we fully understand the issues, but research continues to progress and we’re learning more and more. A recent study by Dr. Engeline van Duijkeren and colleagues from… Continue Reading

MRSP infection in a person

Posted in Dogs
Methicillin-resistant Staphylococcus pseudintermedius (MRSP) is becoming a huge problem in dogs (and to a lesser degree cats). I think it can easily be called an epidemic, and probably even a pandemic, considering the degree of spread, the massive increase in cases and the international distribution of this multidrug-resistant bacterium. Public health concerns regarding MRSP have… Continue Reading

My dog has MRSP… Should I be concerned?

Posted in MRSA/MRSP
This is a question I get a few times a week. Because methicillin-resistant Staphylococcus pseudintermedius (MRSP) infections are becoming so common and people are aware of potential concerns regarding transmission of methicillin-resistant Staphylococcus aureus (MRSA) from pets to people, it’s a logical concern. Here’s my basic thought process when answering this common question: Staphylococcus pseudintermedius is very… Continue Reading

Staphylococcus (pseud)intermedius meningitis in a child

Posted in Dogs
A paper in the International Journal of Infectious Diseases (Durdik et al 2010) describes a case of meningitis in an 11-month-old child caused by S. intermedius. (Presumably, the bacterium was actually S. pseudintermedius and they’re behind the times on identification of / nomenclature of this bacterium). This is the first report of this bacterium as… Continue Reading

Staph pseudintermedius infection in a person

Posted in Dogs, MRSA/MRSP, Other diseases
When I talk about methicillin-resistant Staphylococcus pseudintermedius (MRSP), I usually say that the human health risks are low because human infections are very rare. However, rare doesn’t mean it can’t happen, as demonstrated by a case report entitled "Beware of the Pet Dog: A Case of Staphylococcus intermedius Infection" published in the American Journal of… Continue Reading

Methicilin-resistant Staphylococcus schleiferi in pets

Posted in Cats, Dogs, MRSA/MRSP
When it comes to methicillin-resistant staphylococci in pets, MRSA (methicillin-resistant S. aureus) gets most of the attention. That’s fair since it’s emerging as an important health problem, and can be transmitted between pets and people. Now another staph, MRSP (methicillin-resistant S. pseudintermedius) is getting more attention, and it’s actually a more common cause of infections… Continue Reading

Tea tree oil in dogs

Posted in Cats, Dogs, Other diseases
Skin and soft tissue infections increasingly caused by highly drug-resistant bacteria, along with various concerns about antibiotic use, have led to a desire to find non-antibiotic approaches to treatment of these infections. Tea tree oil has some potent antibacterial properties when tested in the lab, and there are some studies indicating it might be effective… Continue Reading

Should I isolate my dog with MRSP/MRSI?

Posted in Cats, Dogs, MRSA/MRSP, Other diseases
Methicillin-resistant Staphylococcus pseudintermedius (MRSP, sometimes misidentified as methicillin-resistant S. intermedius (MRSI)) is an increasing problem in dogs and cats. This highly drug-resistant bacterium is a particularly problem in skin and ear infections, and the number of infected animals appears to be increasing significantly. A related bug, methicillin-resistant S. aureus (MRSA) has been a major problem… Continue Reading

How long do animals carry MRSP/MRSI?

Posted in Cats, Dogs, MRSA/MRSP, Other diseases
I’ve had this question a lot lately. Methicillin-resistant Staphylococcus pseudintermedius (MRSP), which is sometimes misidentified as methicillin-resistant S. intermedius (MRSI), is an important and increasing cause of infections in dogs and cats. After an animal has had an MRSP/MRSI infection, a question people often ask is how long they will carry the bacterium? MRSP can be… Continue Reading

My dog has an MRSI infection, should I be worried?

Posted in Dogs, Other diseases
Infections caused by methicillin-resistant staphylococci are an increasing problem in veterinary medicine. Staphylococci are a group of bacteria that can cause various infections in many different animal species, including people. The one that gets the most attention is methicillin-resistant Staphylococcus aureus (MRSA). There is more information about MRSA in animals on the Worms & Germs… Continue Reading

Treatment of MRSA and MRSP: more than meets the eye

Posted in Cats, Dogs, MRSA/MRSP
Methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant S. pseudintermedius (MRSP) are important causes of infection in pets, and are resistant to many different antibiotics. It’s therefore very important that these bacteria are cultured and tested in a lab to determine what antibiotics may be effective.  Even then, choosing an effective medication can be difficult due to… Continue Reading

Methicillin-resistant staph: what’s in a name?

Posted in Cats, Dogs, MRSA/MRSP
There is a lot of concern and confusion about methicillin-resistant staphylococcal infections in pets. "Staphylococcus" is genus of bacteria which contains numerous different species. All these species can come in ‘methicillin-resistant’ forms that are resistant to many antibiotics, but some of these species are of greater concern than others. The main species of concern are… Continue Reading
