Case Report of a Diabetic Foot Infection Caused by Staphylococcus pseudintermedius, a Zoonotic Pathogen of Canine Origin

J Am Podiatr Med Assoc. 2022 Nov-Dec;112(6):21-114. doi: 10.7547/21-114.

Abstract

Staphylococcus pseudintermedius is an emerging zoonotic pathogen that is very similar to human Staphylococcus pathogens, particularly multidrug-resistant Staphylococcus aureus. Recent reports have indicated that S pseudintermedius is easily transmitted between pets (mainly dogs) and owners because of these similarities. Although this pathogen has been associated with diabetic foot infections, it has not yet been described in the podiatric medical literature. In this case report, we present a diabetic foot infection in a 61-year-old man that was refractory to multiple rounds of antibiotic drug therapy. Deep wound cultures eventually grew S pseudintermedius, which was the first known case of this pathogen reported in our hospital system.
